Different Knee Injuries
There are a variety of knee injuries that can occur from sports, exercise, or daily activities. It’s important to identify the type of injury to determine the best course of treatment and recovery. One way to visually identify different knee injuries is through pictures.

This article will provide 12 pictures of different knee injuries to help readers identify and understand the various types of knee injuries. The pictures will include common injuries such as ACL tears, meniscus tears, and patellar tendonitis, as well as less common injuries such as Osgood-Schlatter disease and iliotibial band syndrome.

By providing visual examples of knee injuries, readers will be able to better understand the type of injury they may be experiencing and seek appropriate medical attention. It’s important to note that while the pictures can be helpful in identifying injuries, a proper diagnosis from a medical professional is always recommended.

Understanding Knee Anatomy

The knee joint is one of the largest and most complex joints in the human body. It is a hinge joint that connects the thigh bone (femur) to the shinbone (tibia) and the kneecap (patella). The knee joint also includes several ligaments, cartilage, and tendons that work together to provide stability and support to the joint.

The ligaments of the knee joint include the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), lateral collateral ligament (LCL), and medial collateral ligament (MCL). These ligaments help to keep the knee joint stable and prevent excessive movement of the bones.

The knee joint also includes two C-shaped pieces of cartilage called menisci. These act as shock absorbers and help to distribute the weight of the body evenly across the joint.

The articular cartilage covers the ends of the bones within the knee joint. This cartilage is smooth and slippery, allowing the bones to glide over each other with minimal friction.

The quadriceps tendon connects the quadriceps muscle to the patella, while the patellar tendon connects the patella to the tibia. These tendons work together to allow the knee to straighten and bend.

Understanding the anatomy of the knee is important when it comes to diagnosing and treating knee injuries. By knowing the different structures of the knee joint, healthcare professionals can better understand the extent of an injury and develop an effective treatment plan.

Types of Knee Injuries

Knee injuries are common and can be caused by various factors such as sports injuries, accidents, and falls. Knee injuries can be classified into several types based on the severity of the injury. Here are the most common types of knee injuries:

Ligament Injuries

Ligament injuries are common in athletes and can occur due to sudden twisting or hyperextension of the knee joint. The most common ligament injuries are ACL (anterior cruciate ligament) and MCL (medial collateral ligament) injuries. ACL injuries are more severe and can take longer to heal than MCL injuries.

Meniscus Tears

The meniscus is a C-shaped piece of cartilage that acts as a shock absorber in the knee joint. Meniscus tears can occur due to sudden twisting or turning of the knee joint. Symptoms of a meniscus tear include pain, swelling, and difficulty moving the knee joint.

Tendon Tears

Tendon tears can occur due to overuse or sudden trauma. The most common tendon tear is the patellar tendon tear, which connects the kneecap to the shinbone. Symptoms of a tendon tear include pain, swelling, and difficulty moving the knee joint.

Fractures

Knee fractures can occur due to high-impact trauma such as car accidents or falls. Symptoms of a knee fracture include severe pain, swelling, and difficulty moving the knee joint.

Dislocation

Knee dislocation occurs when the bones in the knee joint are forced out of their normal position. This can occur due to high-impact trauma such as car accidents or falls. Symptoms of knee dislocation include severe pain, swelling, and difficulty moving the knee joint.

Sprains

Knee sprains occur when the ligaments in the knee joint are stretched or torn. Symptoms of a knee sprain include pain, swelling, and difficulty moving the knee joint.

Torn Cartilage

Torn cartilage can occur due to sudden trauma or overuse. Symptoms of torn cartilage include pain, swelling, and difficulty moving the knee joint.

In conclusion, knee injuries are common and can be caused by various factors. It is important to seek medical attention if you experience any symptoms of a knee injury.

Causes of Knee Injuries

Knee injuries can occur due to a variety of reasons, ranging from aging to sports-related accidents. Here are some of the common causes of knee injuries:
- Injury: A direct blow to the knee, such as from a fall or collision, can cause knee injuries. Injuries can also occur from twisting or bending the knee in an awkward way.
- Aging: As people age, the cartilage in their knees can wear down, making the knee joint less stable and more prone to injuries.
- Tears: Tears in the knee’s ligaments or menisci can cause pain and instability in the knee. These tears can occur due to sudden twisting or pivoting movements or from overuse.
- Athletes: Athletes who participate in sports that involve running, jumping, or sudden changes in direction are at a higher risk of knee injuries. Contact sports such as football and basketball are particularly high-risk.
- Twisting: Twisting the knee can cause ligament sprains and tears. This can happen during sports, exercise, or even just walking on an uneven surface.
- Contact Sports: Injuries to the knee are common in contact sports such as football, hockey, and rugby. These sports involve a lot of physical contact and can put a lot of stress on the knee joint.
- Motor Vehicle Accident: Knee injuries can also occur as a result of a motor vehicle accident. The force of impact can cause the knee to twist or bend in an unnatural way, leading to injuries.
In summary, knee injuries can occur due to a variety of reasons, ranging from aging to sports-related accidents. It is important to take precautions to prevent knee injuries, such as wearing proper protective gear during sports and exercise, maintaining a healthy weight, and avoiding activities that put excessive stress on the knee joint.

Symptoms of Knee Injuries

Knee injuries can cause a variety of symptoms, depending on the type and severity of the injury. Some common symptoms of knee injuries include:
- Pain: Knee pain is one of the most common symptoms of a knee injury. The pain may be sharp or dull and can be felt in different parts of the knee, depending on the location of the injury.
- Swelling: Swelling around the knee is another common symptom of a knee injury. The swelling may be mild or severe and can make it difficult to move the knee.
- Popping: Some knee injuries may cause a popping sound or sensation in the knee. This may be accompanied by pain or swelling.
- Stiffness: Stiffness in the knee is another common symptom of knee injuries. The knee may feel tight or difficult to move, especially after periods of inactivity.
- Instability: Knee injuries can also cause instability in the knee. This may feel like the knee is giving way or buckling, and can make it difficult to walk or stand.
- Fever: In some cases, knee injuries may cause a fever. This may be a sign of an infection and requires immediate medical attention.
It is important to seek medical attention if you experience any of these symptoms after a knee injury. Prompt treatment can help prevent further damage and improve your chances of a full recovery.

Diagnosis of Knee Injuries

Diagnosing knee injuries can be a complex process that requires a thorough examination by a doctor. In some cases, imaging tests such as an MRI or x-ray may be necessary to accurately diagnose the injury.

When a patient presents with knee pain, the doctor will first ask about the patient’s medical history and the circumstances surrounding the injury. They will then perform a physical examination of the knee, checking for swelling, tenderness, and range of motion.

Depending on the suspected injury, the doctor may order an x-ray to check for fractures or dislocations. An MRI may be ordered to provide a more detailed view of the knee’s soft tissues, such as ligaments and tendons.

Once a diagnosis is made, the doctor will work with the patient to develop a treatment plan that may include rest, physical therapy, or surgery. It is important for patients to follow their doctor’s recommendations to ensure a full recovery and prevent further injury.

In conclusion, diagnosing knee injuries requires a careful examination by a doctor, and imaging tests such as an MRI or x-ray may be necessary. Patients should work closely with their doctor to develop a treatment plan and follow their recommendations for a full recovery.

Treatment for Knee Injuries

When it comes to treating knee injuries, there are several options available depending on the severity of the injury. In some cases, rest and ice may be sufficient, while in other cases, surgery may be necessary.

For minor knee injuries, rest is often the best course of action. This means avoiding activities that put stress on the knee and taking a break from exercise or sports. Applying ice to the affected area can also help to reduce swelling and inflammation.

Physical therapy can be an effective treatment option for knee injuries as well. This involves working with a trained therapist to perform exercises and stretches that can help to strengthen the knee and improve mobility. In some cases, a knee brace may also be recommended to provide additional support and stability.

For more serious knee injuries, surgical treatment may be necessary. This can include procedures such as knee replacement surgery or arthroscopic surgery to repair damaged cartilage or ligaments.

In addition to these treatments, medication may also be prescribed to help manage pain and inflammation. This can include over-the-counter pain relievers such as ibuprofen or prescription medications such as opioids.

Overall, the best course of treatment for a knee injury will depend on the specific nature and severity of the injury. It is important to consult with a medical professional to determine the most appropriate treatment plan.

Complications and Conditions Related to Knee Injuries

Knee injuries can lead to various complications and conditions that can affect the overall health and function of the joint. One of the most common complications of knee injuries is arthritis, which is the inflammation of the joint. Arthritis can be caused by various factors such as age, genetics, and previous injuries.

Osteoarthritis is a type of arthritis that is commonly associated with knee injuries. It occurs when the protective cartilage that cushions the joint wears down over time, causing pain, stiffness, and swelling. Rheumatoid arthritis is another type of arthritis that can affect the knee joint. It is an autoimmune disorder that causes the body to attack its own tissues, including the joint.

Inflammation is another common complication of knee injuries. It occurs when the body’s immune system responds to an injury or infection by releasing chemicals that cause swelling, redness, and pain. This can lead to further damage to the joint and surrounding tissues.

Patellofemoral pain syndrome, bursitis, patellar tendinitis, and iliotibial band syndrome are other conditions that can result from knee injuries. These conditions can cause pain, swelling, and stiffness in the knee joint, making it difficult to move or perform daily activities.

In severe cases, joint replacement surgery may be necessary to treat knee injuries. This involves removing the damaged joint and replacing it with an artificial one. Osteoporosis, a condition that causes the bones to become weak and brittle, can also be a complication of knee injuries, especially in older adults.

Overall, knee injuries can lead to various complications and conditions that can affect the health and function of the joint. It is important to seek medical attention if you experience any symptoms of knee injuries to prevent further damage and complications.

Prevention of Knee Injuries

Preventing knee injuries is important to maintain optimal knee health. Here are a few tips to help prevent knee injuries:
- Stretching: Stretching before and after exercise can help prevent knee injuries. Stretching helps to warm up the muscles and increase flexibility, which can reduce the risk of injury.
- Bearing Weight: Maintaining a healthy weight can help prevent knee injuries. Excess weight puts extra stress on the knees, which can lead to injury over time.
- Wear and Tear: Overuse can lead to wear and tear on the knees, which can cause injury. To prevent this, it is important to rest and take breaks when necessary.
- Calcium: Calcium is important for strong bones, which can help prevent knee injuries. Eating foods rich in calcium, such as dairy products, can help keep bones strong and healthy.
In addition to the above tips, it is important to wear proper footwear when exercising, as well as to use proper technique when performing exercises. By following these tips, individuals can help prevent knee injuries and maintain optimal knee health.

POLARIS AR receives US Food and Drug Administration approval for STELLAR Knee

MIAMI, Nov. 3, 2023 /PRNewswire/ — POLARIS^AR is pleased to announce today that their STELLAR knee has received 510(k) clearance from the U.S. Food and Drug Administration (FDA). STELLAR Knee is the first approval for POLARIS^ARa company focused on creating a new category in surgical guidance in Mixed Reality.

POLARIS^AR and STELLAR Knee are building the intersection of physical surgery and virtual surgical guidance, creating a unique digital operating room environment. This digital OR environment uses Mixed Reality displays to provide surgeons with real-time access to intraoperative anatomical data used to measure, plan and guide total knee arthroplasty procedures. Using a unique combination of proprietary optical tracking algorithms and spatial computing software, STELLAR Knee measures and records clinically meaningful hard and soft tissue anatomical data, enabling sub-millimetric intraoperative planning and providing precise resection accuracy and guidance.

“This is an important moment for orthopedic surgery,” said Dr. John Cooper, associate professor of orthopedic surgery, Columbia University Irving Medical Center. “Before STELLAR Knee, I had to rely on the inaccuracy of conventional instruments, or on complex technologies such as robotics to improve surgical precision. While these technologies provide important data that can be used to personalize surgery for each patient, they require a large footprint in my OR and a significant financial commitment from my institution. Now I can wear an unobtrusive digital assistant that provides real-time measurements and calculations I can trust, validating surgical decisions.”

With no footprint in the operating room other than a Mixed Reality headset that acts as a three-dimensional spatial computing tool, STELLAR Knee dynamically acquires patient-specific anatomical data and digitizes that information into holographic displays. By capturing the surgeon’s field of view, STELLAR Knee creates a real-time digital data exchange between the surgeon and the technology that supports clinical decisions. Surgeons have full interactive capabilities with the highly customizable and intuitive user interface, allowing them to make quick assessments and micro-adjustments to the surgical plan.

With minimal physical installation, a simple integration process and competitive pricing compared to traditional surgical guidance systems, STELLAR Knee has the ability to shift the standard of care. The STELLAR Knee workflow is open and available for use in all total knee replacement implant systems. POLARIS^AR and STELLAR Knee are creating a new category in surgical guidance software that leverages the latest visual display technology.

“One of the most important aspects of new technology entering the operating room is the impact it makes and the footprint it requires,” said Dr. Francis Gonzales, professor of orthopedic surgery, University of California, San Diego. “Technological progress does not always correlate with improvements within the OR. STELLAR Knee is an exception. Because it has no footprint outside the headset, no computers or stalls, it does exactly what it was designed to do: it allows me to focus on what matters most: the operation, and to have confidence in the decisions I make. take.”

“Our software has the power to usher in the next generation of surgical advancements,” said Paul Mikus, Chief Executive Officer of POLARIS^AR. “This is a new day for orthopedics and surgery as a whole, as the promise of Augmented Reality is now being fulfilled. STELLAR Knee is pioneering a new class of surgical software that leverages best-in-class spatial computing and optimizes operating room workflow. STELLAR Knee not only impacts the surgeon and the patient, but also empowers healthcare providers to change the standard of care.”

Yes, men run faster than women, but over shorter distances – not by much

Conventional wisdom holds that men run 10 to 12 percent faster than women, regardless of distance covered. But new research suggests the performance gap between the sexes is much smaller over shorter sprint distances.

It has long been known that men outperform women by relatively large margins in middle and longer distance events. But speed over short distances is determined by several factors – most notably the magnitude of the ground forces athletes can exert in relation to their body weight. Women tend to be smaller than men and, all things being equal, the ratio of muscle strength to body weight is greater in smaller individuals.

Ph.D. candidate Emily McClelland, working with Peter Weyand, the director of SMU’s Locomotor Performance Lab, quantified differences in sex performance using data from sanctioned international athletic competitions such as the Olympic Games and World Championships. They hypothesized that this data would reveal smaller performance differences between men and women over shorter distances.

An accomplished athlete and former associate director of strength and conditioning at Bowling Green State University, McClelland has always had a natural interest in the scientific basis of human performance.

More generally, understanding the relative strength, speed and endurance capabilities of male and female athletes is a very challenging issue for modern sport. Yet prior to the new SMU research, the quantitative understanding of gender performance differences in short sprint events had received little attention. McClelland’s background, gender differences in strength/mass capabilities, and existing data trends led her to hypothesize that gender differences in sprint performance might be relatively small and increase with distance.

Her analysis of race data from sanctioned international competitions between 2003 and 2018 supported her initial hypothesis. This data showed that the difference between men’s and women’s performance times increased with the distance between events, from 8.6 percent to 11 percent, from the shortest to longest sprint events (60 to 400 meters). Furthermore, within-race analysis of each 10-meter segment of the 100-meter event revealed a more pronounced pattern over the distance: gender differences increased from a low of 5.6 percent for the first segment to a high of 14.2 percent in the last segment .

Why then are women potentially less disadvantaged compared to men over shorter sprint distances?

Unlike other running species such as horses and dogs, there is significant variation in body size between human males and females. All other factors being held equal, differences in body size result in a muscle strength to body weight ratio that is greater in relatively smaller individuals. Because sprint speeds are directly dependent on the mass-specific forces that runners can exert during the foot-ground contact phase of the stride, greater force-to-mass ratios of smaller individuals provide a theoretical relative advantage. Additionally, a female runner’s shorter legs can provide the advantage of more steps and push cycles per unit time during the acceleration phase of a race. These factors offset the advantages of men (longer legs and greater muscularity) gaining more leverage over longer distances.

Take the example of Shelly-Ann Fraser Pryce, a Jamaican track star who stands 6 feet tall, weighs 115 pounds and has won two gold medals at the Olympics and five at the World Championships in her signature event, the 100 meters. The 40 yards of a 100-yard race is estimated at just 4.51 seconds – a time faster than nearly half of all wide receivers and running backs who tested in the National Football League’s Scouting Combine in 2022. According to Shelly-Ann Fraser-Pryce, most of these aspiring NFL football players are over 6 feet tall and 200 pounds.

The study ‘Sex differences in human running performance: smaller gaps over shorter distances?’ was conducted by McClelland and Weyand and has been published in the journal Journal of Applied Physiology.

Headgear can reduce concussion risk in high school lacrosse
Association headgear mandate and concussion injury rates in girls high school lacrosse

Herman DC, Caswell SV, Kelshaw PM, Vincent HK, Lincoln AE. Br J Sports Med. 2022;56:970-974. doi:10.1136/bjsports-2021-105031

https://bjsm.bmj.com/content/56/17/970.long

Take home message

Headgear can reduce the risk of concussions in high school lacrosse field players.

Background

Current regulations classify women’s lacrosse as a non-contact sport, limiting the amount of protective equipment required for goggles and mouthguards. However, unintentional head impacts (such as head-to-stick) are common, often leading to a concussion. There is little evidence to assess whether headgear reduces the risk of concussion in this population.

Study aim

The authors wanted to determine whether high school girls’ lacrosse players had fewer concussions in a state with a headgear mandate than players in states without a headgear mandate.

Methods

The authors used an existing data recording system (the High School National Athletic Treatment, Injury, and Outcomes Network [NATION]) to analyze athlete exposures and concussions. Each athlete exposure represented a single athlete participating in a high school sanctioned practice or competition. A concussion had to occur during a high school lacrosse game or practice and be diagnosed by a healthcare professional. The authors compared data from Florida, which has a statewide headgear mandate, with athletes in 31 other states without a mandate. They focused on data from 2019-2021.

Results

In total, the authors analyzed 289 school seasons (96 with mandatory helmets), yielding 357,225 exposures to athletes (91,074 with mandatory helmets). During these exposures, 141 concussions occurred. Lacrosse players competing in states without a headgear mandate had a ~59% greater incidence of concussion than players in a state with a mandate.

Viewpoints

This study adds to the limited literature suggesting that headgear can reduce the risk of concussion in female high school lacrosse players. More states and lacrosse organizations should consider implementing a similar mandate to reduce the incidence of concussions in this athletic population. Unlike previous research, this study simultaneously tracked both mandatory and non-mandatory headgear concussions, which increases its potency. However, several limitations are also present. First of all, this study lacks randomization of participants. Therefore, athletes with helmet mandates (mainly Florida) may be unique compared to other players. This may include differences in refereeing style and player intensity. Second, some lacrosse players in states without a mandate may have worn helmets based on their preferences. It is unclear how many athletes in the states without a mandate voluntarily wore helmets and may have been protected. Therefore, these results could underestimate the benefit of helmets.

Clinical implications

Athletic trainers and other sports medicine professionals should advocate for headgear mandates and resources to ensure access to headgear in women’s lacrosse to potentially reduce the incidence of concussions.

Questions for discussion

What are your thoughts on the ability of helmets and headgear to reduce the risk of concussion in athletes? Does this study change your view on their ability to reduce the incidence of concussions?

COVID-19 pandemic cancellations have taken a heavy toll on teen athletes, whose mental and physical health improved significantly after sports resumed, research shows

High rates of depression and anxiety among adolescent athletes whose sports were canceled during the COVID-19 pandemic improved significantly a year later when they were able to return to sports, according to new research.

The author of an abstract, “The Influence of Return to Sport on Mental Health, Physical Activity and Quality of Life Among Adolescent Athletes During COVID-19,” will present his findings at the AAP 2022 National Conference and Exhibition in Anaheim, CA.

“Organized sports participation has been shown for decades to have significant physical and mental health benefits for adolescents, but the COVID-19 pandemic has made this even clearer,” said author Drew Watson, MD, MS, team physician for athletics from the University of Wisconsin.

“The cessation of sports during the early pandemic was associated with reduced physical activity and quality of life, as well as surprisingly high levels of anxiety and depression. Although the return to sport has been associated with major improvements in physical activity, quality of life and mental health, we are still seeing higher levels of anxiety and depression than before COVID-19, suggesting this will be a crucial priority in the coming years to stay.”

According to the summary, a total of 17,421 teens nationwide completed surveys in May 2020, including information on demographics and sports participation, following cancellations of sporting events related to COVID-19 and following their return to sports in May 2021.

When sports were stopped, adolescent athletes reported low levels of physical activity, poor quality of life, and high rates of anxiety and depression. A year later, the athletes who were able to return to sports reported a significant increase in physical activity and quality of life. The percentage of adolescents reporting moderate to severe anxiety or depression fell by about half.

Dr. Watson suggests that the opportunity to participate in organized sports can have dramatic benefits for adolescents’ quality of life and mental health.

Help reduce injuries by having a fun and fit warm-up with FIFA 11+ Kids
The FIFA 11+ Kids Injury Prevention Program reduces injuries among male football players: a clustered randomized controlled trial.

Al Attar WSA, Bizzini M, Alzahrani H, Alarifi S, Ghulam H, Alyami M, Alzhrani M, Sanders RH. Sports Health. July 28, 2022: 19417381221109224. doi: 10.1177/19417381221109224. E-publishing prior to printing. PMID: 35903029.

https://pubmed.ncbi.nlm.nih.gov/35903029/

Take home message

Footballing children who completed the FIFA 11+ Kids program suffered fewer injuries than those who completed the normal warm-up.

Background

Children under the age of 14 sustain almost 44% of all football injuries. Warm-up programs for injury prevention could reduce the number of injuries in this population and future health care costs. However, we know little about the effectiveness of these programs in youth football.

Study aim

The authors evaluated the effect of the FIFA 11+ Kids injury prevention program on reducing the incidence of injuries among male Saudi Arabian football players aged 7 to 13 years.

Methods

The authors conducted a cluster randomized control trial to assess the effect of the 11+ Kids program on reducing injuries in 7- to 13-year-old football players over 1 season (August 2018 – January 2019). The authors sent recruitment letters to 100 male soccer teams (825 athletes) participating in the Saudi Federation of Sports Medicine and Saudi Soccer Federation soccer teams. In response, 88 teams (740 players) agreed and completed the study. The authors randomized 45 soccer teams into the 11+ Kids program (377 athletes). The 11+ Kids program consisted of a 15-20 minute warm-up (7 exercises; 5 levels; focused on balance, core stability and optimization of falling technique) to be performed twice a week instead of a regular warm-up . The control group (43 teams, 363 athletes) performed their regular warm-up regimen, which was defined as basic exercises performed before a match or training to prepare the player for vigorous physical activity. The authors defined an injury as one that prevented a player from fully participating in the next match or training session.

Results

The soccer players who completed the 11+ Kids program had ~57% fewer injuries than players who performed a traditional warm-up. The benefit of the 11+ Kids program appears to apply to contact, non-contact and overuse injuries. The authors provide a detailed overview of the different types of injuries, but in many of them only a few athletes (<5 athletes) had an injury, making it difficult to interpret.

Overall, athletes who completed the 11+ Kids program suffered 57% fewer injuries than the control group, demonstrating the need for prevention programs such as the FIFA 11+ Kids in youth soccer programs. These findings are consistent with a wealth of research showing that prevention programs work and can be easily implemented in less than 15 minutes. In this study, the coaches used the program just twice a week and saw benefits, suggesting that coaches do not need to completely abolish their existing warm-up programs. While we often focus on high school and college athletes, it’s reassuring to see these programs working for elementary and middle school players.

Clinical implications

Medical professionals should encourage youth coaches to use injury prevention warm-up programs, such as FIFA 11+ Kids, to reduce injuries at this level and promote positive future health outcomes.

Questions for discussion

What is the best way to distribute this information to the youth leagues? Does your youth athlete perform a structured warm-up? Do you think this is easy to implement?

The number of children hospitalized for e-scooter injuries increases between 2011 and 2020

Upright electric scooters, commonly referred to as e-scooters, have grown in popularity across the country over the past decade. According to a new research summary presented at the 2022 American Academy of Pediatrics National Conference & Exhibition, e-scooter injuries are becoming much more common and increasingly serious.

Authors of the abstract “National Trends in Pediatric e-Scooter Injury” found hundreds of e-scooter injuries between 2011 and 2020. Patient hospitalizations have increased from less than 1 in 20 e-scooter injuries in 2011 to 1 in 8 requiring hospitalization for care in 2020.

“The number of annual e-scooter injuries increased between 2011 and 2020, likely in part due to the rising popularity of e-scooter ride-sharing apps,” said lead author Harrison Hayward, MD, Emergency Medicine fellow at Children’s National Hospital. “Our research has characterized the spectrum of injuries that occur in children, allowing emergency physicians to prepare to care for them and parents and families to practice better safety.”

Researchers examined a national database of e-scooter injuries to children seen in the emergency departments of more than 100 U.S. hospitals between 2011 and 2020 to find out what types of injuries children suffered and if there were any trends. More than 10% of all patients had head injuries, including concussion, skull fractures and internal bleeding. The most common injuries were arm fractures (27%), followed by minor abrasions (22%) and cuts requiring stitches (17%). The mean age was 11.1 years and 59% of patients were male. Hospital admissions increased from 4.2% in 2011 to 12.9% in 2020.

“Parents whose children ride e-scooters need to know how best to be safe. That’s why helmets are a must, as more than 10% of reported cases involved head injuries,” said Dr. Hayward. “Children should absolutely wear helmets when riding an e-scooter. Research has broadly shown that helmets save the lives of cyclists, and we should think the same way about e-scooters.”

The authors received no financial support for this research.

Coach the coach, make ACL injury prevention programs stick!

Coach training improves adherence to anterior cruciate ligament injury prevention programs: a cluster randomized controlled trial. Clinical Journal of Sports Medicine

Ling, Daphne I; Boyle, Caroline; Schneider, Brandon; Janosky, Joseph; Childservant, James; Marx, Robert G. Clin J Sport Med. July 2022 – Part 32 – Number 4 – p. 348-354. doi: 10.1097/JSM.0000000000000936

Take home message

Coaches who received education about anterior cruciate ligament (ACL) injury prevention were more likely to include it in their warm-up. Personal training sessions increased the use of proper alignment cues and the incorporation of a complete prevention program.

Background

Neuromuscular training programs can reduce an athlete’s chance of an ACL injury and can be incorporated as a simple warm-up. However, few coaches use warm-up programs for injury prevention.

Study aim

Ling and colleagues completed a cluster randomized controlled trial to investigate whether live educational training for coaches with take-home documents led to better adherence to a neuromuscular training program for their teams than coaches who only received program information via email received.

Methods

The authors recruited coaches via email to athletic directors at high schools with which the authors’ institution had ties. The authors excluded schools that had previously implemented a neuromuscular training warm-up program. High schools interested in participating in the study were randomized to receive live education for coaches with reference documents or educational documents only. Coaches from schools randomized to the intervention attended a live education session and received a reference video and follow-up documents for a series of neuromuscular training warm-up routines (beginner to elite) containing 7-10 exercises. Coaches from schools in the control group only received the documents in an email. Trained data collectors observed all teams 2-3 times per week during both practices and games. They checked that the coaches performed the neuromuscular training exercises, provided instructions on the correct execution and gave the correct instructions for the technique.

Results

The authors randomized 8 high schools, including 21 teams. Over two seasons, the data collectors observed 399 practices or games and 2,579 practices. Coaches in the intervention group used ~7 exercises per session, while coaches in the control group used only ~6 exercises. More coaches in the intervention completed a full neuromuscular training warm-up program and provided prompts to correct incorrect techniques than coaches who only received the documents.

Viewpoints

As I suspect, the findings of this study support training coaches on proper techniques and drills in a live format. The authors used a combination of lectures and practical skills training during a 1-hour teaching session. Completing this educational session allowed coaches to ask questions, gain clarity and better understand the need to implement the program properly throughout the season. Having data collectors on site regularly throughout the seasons may have made coaches more compliant. However, coaches did not know when the data collectors would be present, making the data valid because coaches did not perform the prevention exercises in a performative manner only because they believed they were being watched. It would be interesting to see if this educational session could help coaches in more high schools and if other teachers could effectively deliver this educational session.

Clinical implications

Clinicians should organize educational workshops for coaches to help them implement proven ACL injury prevention programs as part of their warm-up routine. These workshops can be provided by the physician, another local health care professional, or a coach with experience using these programs.

Questions for discussion

Would the implementation of exercises be higher if coaches could choose from a group of useful exercises for their team, thereby increasing “buy-in”?

Would governing bodies that approve programs and recommend training of coaches in these programs specific to their sport increase adherence and appropriate implementation or discourage participation?
