    Anatomy of the Knee

    v2 1ziew 217ph

    The knee is a complex joint that connects the thighbone (femur) to the shinbone (tibia). It is the largest joint in the body and is responsible for supporting our body weight and allowing us to walk, run, jump, and pivot. The knee joint is made up of bones, tendons, ligaments, cartilage, and bursae that work together to provide stability and mobility.

    Bones and Joints

    The knee joint is made up of three bones: the femur, tibia, and patella (kneecap). The femur is the long bone in the thigh, while the tibia is the large bone in the shin. The patella is a small, triangular bone that sits in front of the knee joint. The knee joint is a hinge joint, which means it can bend and straighten like a door hinge. The joint is held together by a joint capsule, which is a thin, fibrous sac that surrounds the joint.

    Tendons and Ligaments

    Tendons are tough, fibrous cords that connect muscles to bones. The patellar tendon connects the kneecap to the shinbone, while the quadriceps tendon connects the quadriceps muscles to the kneecap. Ligaments are strong, fibrous bands that connect bones to other bones. The knee joint has four main ligaments: the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL). These ligaments provide stability to the knee joint and help prevent excessive movement in any direction.

    Cartilage and Menisci

    Cartilage is a tough, rubbery tissue that covers the ends of bones. The knee joint has two types of cartilage: articular cartilage and meniscal cartilage. Articular cartilage covers the ends of the femur, tibia, and patella, allowing the bones to glide smoothly against each other. Meniscal cartilage is located between the femur and tibia and acts as a shock absorber, helping to distribute weight and reduce friction in the knee joint.

    Bursae and Muscles

    Bursae are small, fluid-filled sacs that cushion and lubricate joints. The knee joint has several bursae that help reduce friction between the bones, tendons, and ligaments. The muscles around the knee joint include the quadriceps, hamstrings, and calf muscles. These muscles work together to move the knee joint and provide stability to the knee.

    In summary, the knee joint is a complex structure made up of bones, tendons, ligaments, cartilage, and bursae that work together to provide stability and mobility. Understanding the anatomy of the knee is important for anyone experiencing knee pain or injury, as it can help guide diagnosis and treatment.

    Common Causes of Knee Pain

    One of the most common causes of knee pain is injury or trauma to the knee. This can include a dislocated knee, torn cartilage, torn meniscus, dislocated kneecap, or fracture. Knee injuries can be caused by a variety of factors, including sports, falls, and car accidents.

    Arthritis and Other Diseases

    Arthritis is another common cause of knee pain. Osteoarthritis is the most common form of arthritis that affects the knee. It is a degenerative disease that occurs when the cartilage in the knee joint wears down over time. Rheumatoid arthritis is another type of arthritis that can affect the knee joint. Other diseases that can cause knee pain include gout and infections.

    Overuse and Stress

    Overuse and stress are also common causes of knee pain. This can include tendinitis, which is an inflammation of the tendons that attach muscles to bones. Patellar tendinitis, also known as jumper’s knee, is a type of tendinitis that affects the patellar tendon. This condition is common in athletes who participate in sports that require a lot of jumping or running.

    In conclusion, knee pain can be caused by a variety of factors, including injuries, arthritis, and overuse. If you are experiencing knee pain, it is important to see a doctor to determine the cause and get the appropriate treatment.

    Diagnosis of Knee Pain

    v2 1zifc 6ydnk

    When it comes to diagnosing knee pain, a physical examination is usually the first step. During the exam, a doctor will check for redness, swelling, stiffness, and any signs of fever. They will also ask about the patient’s medical history and any recent injuries or activities that may have caused the pain.

    Physical Examination

    During a physical examination, the doctor will check the knee’s range of motion, strength, and stability. They may also perform specific tests to check for ligament or meniscus injuries. These tests can include the Lachman test, pivot shift test, and McMurray test.

    Imaging Tests

    If the physical examination does not provide enough information, the doctor may order imaging tests such as an X-ray, MRI, or CT scan. X-rays can help diagnose fractures or arthritis, while MRIs and CT scans can provide more detailed images of soft tissue injuries.

    In some cases, a doctor may also perform an arthroscopy, which is a minimally invasive procedure that allows them to look inside the knee joint and diagnose any issues.

    Overall, it is important to see a doctor if you are experiencing knee pain. They can help diagnose the issue and provide appropriate treatment to help alleviate the pain and prevent further damage.

After each exercise, it’s important to conduct an after-action report to evaluate our performance and make improvements.

    Full-scale exercises are another important tool in emergency preparedness. These exercises involve a coordinated response from multiple agencies and stakeholders and allow us to test our emergency plans in a more realistic scenario.

    The Federal Emergency Management Agency (FEMA) provides a wealth of tools and resources for emergency management. This includes the Incident Command System (ICS), which provides a standardized framework for managing emergency situations. FEMA also offers guidance on developing emergency plans, conducting exercises, and evaluating performance.

    Effective emergency management requires clear roles and responsibilities for all stakeholders, including emergency managers, first responders, and community partners. It’s important to establish lines of communication and ensure that everyone is aware of their role in an emergency situation.

    In conclusion, harm reduction is about minimizing the negative impact of health behaviors, including emergencies. By taking the time to plan and prepare for emergencies, conducting tabletop exercises and drills, and utilizing resources from FEMA, we can be better prepared to respond to unexpected events and protect our communities.

    Understanding Knee Anatomy

    v2 1zjgu fvv3r

    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

    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.

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

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

    MIAMI, Nov. 3, 2023 /PRNewswire/ — POLARISAR 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 POLARISARa company focused on creating a new category in surgical guidance in Mixed Reality.

    POLARISAR 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. POLARISAR 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 POLARISAR. “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

    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

    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.

    CTL Amedica will present the MONDRIAN™ ALIF system at the University of Miami on November 4

    Spine surgeons and distributors are welcome

    DALLAS, November 3, 2023 / OrthoSpineNews/ – On November 4, CTL Amedica will introduce surgeons and distributors to the new MONDRIAN™ Anterior Lumbar Interbody Fusion (ALIF) System during a special hands-on laboratory. The laboratory will be held in the Minimally Invasive Surgical Training and Education Center, located in the Rosenstiel Building at the University of Miami.

    This will be the spine industry’s first official, hands-on look at the MONDRIAN™ ALIF System. The FDA-cleared implant system is an integrated plate-and-cage construction made of titanium and featuring CTL Amedica’s patented TiCRO™ surface technology, which enhances the interlocking properties of bones.

    “The MONDRIAN™ ALIF System is designed to provide anterior column stabilization and supplemental fixation while accommodating a wide range of patient anatomies and surgical preferences,” said Daniel Chon, CEO of CTL Amedica. “It is a unique implant that we believe will be very useful to surgeons and their patients, and we are excited to demonstrate this important technology this coming weekend at the University of Miami.”

    Named after the influential, early 20se century artist Piet Mondrian, the MONDRIAN™ ALIF System features a smooth, tapered leading edge for easy insertion, a large central chamber for maximum biological graft volume, a proprietary screw locking mechanism and an additional screw blocking plate for additional reinforcement.

    Additionally, the MONDRIAN™ ALIF System features hyperlordotic cages for complex corrections, multiple screw plate configurations for greater operational versatility, and CTL Amedica’s patented and precision machined TiCRO™ surface technology, which provides a larger surface area than predicates, increasing contact with the bony endplates is significantly increased. .

    The educational laboratory is open to all surgeons and distributors, but participation space is limited. For more information, contact info@ctlamedica.com or call 1-800-713-9489.
