What are the different types of traumatic knee injuries?

Types of Traumatic Knee Injuries: A Comprehensive Overview

Traumatic knee injuries are a common occurrence in sports medicine and can cause significant pain and discomfort. Knee injuries involve trauma to one or more tissues that make up the knee joint, including bones, ligaments, cartilage, meniscus, and tendons. In many cases, injuries involve more than one structure in the knee.

There are various types of traumatic knee injuries, and each injury requires a unique treatment approach. Some of the most common types of knee injuries include fractures, dislocations, tears of the anterior cruciate ligament (ACL), and tears of the meniscus. Knee injuries can occur due to a fall, forceful twisting of the knee, or high impact from a motor vehicle accident or another force.

In this article, we will discuss the different types of traumatic knee injuries, their causes, symptoms, and treatment options. We will also provide tips for preventing knee injuries and maintaining healthy knee joints. Understanding the different types of knee injuries can help you take the necessary steps to prevent them and seek appropriate medical care if you experience knee pain or discomfort.

Types of Knee Injuries

When it comes to knee injuries, there are several types of traumatic knee injuries that can occur. Here, we will discuss some of the most common types of knee injuries and their subtypes:

Ligament Injuries

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 can be sprained or torn due to a fall, sports injury, or accident. Symptoms of a ligament injury may include pain, swelling, and instability in the knee joint.

Meniscus Injuries

The meniscus is a C-shaped piece of cartilage in the knee joint that acts as a shock absorber. Meniscal tears are a common type of knee injury that can happen due to a twisting motion or direct impact to the knee. Symptoms of a meniscal tear may include knee pain, swelling, and difficulty moving the knee joint.

Tendon Injuries

The knee joint also has two main tendons: the patellar tendon and the quadriceps tendon. These tendons can tear due to overuse or direct impact to the knee joint. Symptoms of a tendon tear may include inflammation, pain, and difficulty moving the knee joint.

Fractures

A knee fracture occurs when one or more of the bones that make up the knee joint (patella, femur, or tibia) break due to a fall, sports injury, or accident. Symptoms of a knee fracture may include severe pain, swelling, and difficulty moving the knee joint.

Dislocations

A knee dislocation occurs when the bones that make up the knee joint (patella, femur, or tibia) are forced out of their normal position. This can happen due to a fall, sports injury, or accident. Symptoms of a knee dislocation may include pain, swelling, and instability in the knee joint.

In conclusion, knee injuries can be painful and debilitating. If you experience any symptoms of a knee injury, it is important to seek medical attention right away. Treatment options may include rest, physical therapy, or surgery depending on the severity of the injury.

Diagnosis and Treatment

Clinical Assessment

When a patient presents with a traumatic knee injury, we first perform a clinical assessment to determine the extent and severity of the injury. This includes evaluating the patient’s medical history, performing a physical examination, and assessing the patient’s symptoms, such as swelling, pain, and stiffness.

Imaging Techniques

Imaging techniques, such as x-rays, MRI, and CT scans, may be used to further assess the injury and determine the appropriate treatment approach. X-rays are useful for evaluating bone fractures, while MRI and CT scans are better for assessing soft tissue injuries, such as ligament or cartilage tears.

Treatment Approaches

Treatment for traumatic knee injuries varies depending on the extent and severity of the injury. In some cases, rest, ice, compression, and elevation (RICE) may be sufficient to manage symptoms and promote healing. In more severe cases, surgery may be necessary to repair or reconstruct damaged ligaments, cartilage, or bones.

Rehabilitation and Recovery

Physical therapy is an important part of the recovery process for patients with traumatic knee injuries. Physical therapy can help reduce pain and swelling, improve range of motion, and strengthen the muscles around the knee joint. Patients may also benefit from exercises and stretching to improve flexibility and mobility.

In summary, diagnosis and treatment of traumatic knee injuries requires a comprehensive approach that includes clinical assessment, imaging techniques, and appropriate treatment approaches. Rehabilitation and recovery through physical therapy and exercise are also important for promoting healing and returning to normal activities.

Inspired Spine unveils two Centers of Excellence for high BMI patients in rural Minnesota and Kansas

Inspired Spine CMO Dr. Hamid Abbasi performs one of more than 1,700 OLLIF procedures. The procedure has proven effective in hundreds of patients with a high BMI.

BURNSVILLE, Minn., Nov. 29, 2023 /PRNewswire/ — Inspired Spine has announced the formation of two new Centers of Excellence focused on providing complex spine care, including fusion surgery, to patients with high Body Mass Index (BMI) in rural areas of Minnesota and Kansas, a groundbreaking turn in modern spine health management.

In a remarkable display of dedication, Dr. Hamid Abbasi, a renowned neurosurgeon and the driving force behind Inspired Spine, recently performed an extraordinary feat by traveling to Hutchinson, Kansas to perform eleven spinal surgeries in just two days. Notably, five of these patients had a BMI over 40, with the highest BMIs being 54 and 64. All eleven operations were performed with unprecedented success and the patients were able to walk back and forth in the comfort of their own home within two days.

Traditionally, patients with a BMI above 40 face significant challenges in seeking elective surgeries due to societal norms and medical recommendations against such procedures citing high risks. Inspired Spine’s innovative Oblique Lateral Lumbar Interbody Fusion (OLLIF) technology and comprehensive surgical protocols have dramatically minimized associated risks for patients requiring spinal fusion surgery. Many of them have become non-ambulatory due to spinal problems and have no alternative. The benefits of OLLIF now impressively outweigh the risks.

This advancement comes at a crucial time for patients with high BMI, who often face a debilitating cycle of weight gain and deteriorating health due to the lack of mobility and associated comorbidities, such as cardiovascular decline. In response, Inspired Spine has established specialty medical centers accessible to patients from across the United States that provide advanced and life-changing care.

With a ten-year track record of successfully treating patients with a high BMI with the OLLIF procedure. This breakthrough has opened new doors to patient care that many thought were permanently closed. Despite the complex nature of these operations, patients are typically discharged only one or two nights after surgery and can return home within a few days – undeniable proof of the high efficiency and effectiveness of the treatment.

To underline this success, the publication of Inspired Spine’s OLLIF high BMI paper shows the transformative effects of this procedure. “We are proud to bring our innovation to rural Kansas,” said Dr. Abbasi. “The impact is already being felt with a series of successful surgeries performed in environments that would not normally be suitable for traditional spine surgery. Many of these patients require higher levels of care such as ICU or blood transfusions and intensive medical care due to the invasiveness of traditional surgeries.”

The human dimension of these successes is vividly reflected in patient testimonials. A recent patient from North Carolina who traveled to Inspired Spine of Kansas for the OLLIF procedure shares her experience: “I never thought relief was possible until I found Inspired Spine. The OLLIF procedure not only gave me back my mobility, but also gave me a new lease on life. The care I received in Kansas was exceptional, and I am grateful for the team at Inspired Spine.” Her story, along with her moving testimony and images, underscores the critical importance and positive results of the Centers of Excellence at Inspired Spine.

Inspired Spine is a total spine care provider dedicated to improving patients’ quality of life with revolutionary procedures and technologies. Our commitment to advancing spine health, grounded in innovation, has made us leaders in the field of minimally invasive spine surgery.

Orthofix announces publication in The Spine Journal of five-year data for the M6-C artificial cervical disc

With more than 100,000 implants worldwide, the M6-C and M6-L drives continue to demonstrate strong clinical performance, safety and patient benefits

The Orthofix M6-C™ artificial intervertebral disc is a next-generation artificial intervertebral disc designed to replace an intervertebral disc damaged by degeneration of the cervical intervertebral discs. The M6-C disc is designed to restore spinal motion and is an alternative to cervical fusion.

LEWISVILLE, Texas, November 29, 2023–(BUSINESS WIRE)–Orthofix Medical Inc. (NASDAQ:OFIX), a leading global spine and orthopedics company, today announced the release of the five-year results of its US clinical trial comparing the M6 -C^™ artificial cervical disc with anterior cervical discectomy and fusion (ACDF). Published in The Spine diarypatients treated with the M6-C disc demonstrated superior clinical success at 60 months compared to ACDF patients. Secondary findings indicated significant improvements in neck and arm pain, function and quality of life. The M6-C patient group maintained flexion-extension and lateral bending motion as reported at previous time points. The release of these data coincides with the recognition that more than 100,000 implantations of the M6-C artificial cervical disc and the M6-L artificial lumbar disc (available outside the US only) have been performed worldwide since the product was first introduced in 2006.

“Publication of these data is important as it validates the strong clinical performance observed in the five-year data from the US IDE study,” said lead author Dr. Frank Phillips, professor of orthopedic surgery at Rush University Medical Center in Chicago and the director investigator for the FDA clinical trial. “Artificial intervertebral disc replacement is becoming the gold standard of care for indicated patients who might otherwise experience intervertebral disc fusion. Data from this study demonstrate that the M6-C artificial disc demonstrated superior clinical success over five years compared to ACDF controls. Furthermore, significantly more subjects in the M6-C group reported improved pain and physical functioning scores than observed in ACDF subjects, with no difference in reoperation rates or safety outcomes.”

A prospective, nonrandomized, concurrently controlled clinical trial, the M6-C IDE study, was conducted at 23 sites in the United States with a mean patient age of 44 years. The study evaluated the safety and effectiveness of the M6-C artificial cervical disc compared to ACDF for the treatment of symptomatic single-level cervical radiculopathy with or without umbilical cord compression. The overall success rate for the protocol-specified primary endpoint for the M6-C disk patients was 82.3 percent, compared to 67.0 percent in the control group. The rates of subsequent surgical intervention (SSI) on the M6-C drive were 3.1 percent, device or procedure related serious adverse events (SAE) were 3.1 percent and were comparable to ACDF rates of SSI of 5.3 percent and SAE failure of 4.8 percent. The M6-C drive received U.S. Food and Drug Administration (FDA) approval in February 2019 based on the two-year results of this study.

“To date, there have been more than 100,000 implants of M6 artificial disc technology in 20 countries around the world,” said Kevin Kenny, president of Orthofix Global Spine. “We are proud of this life-changing technology that has helped so many people enjoy their lives again.”

About the M6-C artificial cervical disc

The M6-C artificial cervical disc is designed to maintain the natural behavior of a functional spinal unit by replicating the biomechanical characteristics of the original disc and is indicated as an alternative to cervical fusion. The unique design of the M6-C disc features a compressible viscoelastic core core and annular structure construction that allows shock absorption at the implanted level, providing a controlled range of motion as the spine transitions into its combined complex movements.

Athletic trainers can assist with communication between coach and athlete
Provision of concussion information by coaches and attendance of athletic trainers: Findings from the 2021 YouthStyles Survey

Daugherty J, Waltzman D, Sarmiento KJ Athl Trein. January 16, 2023. doi: 10.4085/1062-6050-0454.22. E-publishing prior to printing. PMID: 36645830.

Full text freely available

Take home message

More than 40% of adolescents participating in sports reported that their coach had not provided them with concussion information in the past year. This lack of communication may be linked to a lack of access to athletic trainers during games and practices.

Background

Coaches can provide concussion education and make a positive impact by translating concussion knowledge into healthy behaviors, such as reporting suspected concussions. Coaches who complete concussion training and relay that information to their athletes positively impact an athlete’s perspective on concussions. However, it is unknown how often coaches discuss concussion education with the athletes and whether the presence of an athletic trainer helps with better communication between coach and athlete.

Study aim

The authors used survey data to examine how often coaches provided concussion safety information to their athletes and whether this varied based on the presence of athletic trainers at games and practices.

Methods

In June 2021, adolescents living with Ipsos Knowledge Panel member parents were invited to complete the annual YouthStyle Web-based survey. Approximately 48% of invited adolescents completed survey questions about history of concussions, information about concussion safety, how concerned they think their coach is about concussion safety, and the frequency of athletic trainers at games and practices in the past year . The authors took statistical steps to ensure that the data represented adolescents across the United States.

Results

Of the 829 adolescents, 39% reported having participated in sports in the past twelve months: 1) only in school sports (19%), 2) only in sports competitions (13%), or both (7%). The most commonly reported sports were basketball and football. Nearly half (47%) of youth athletes reported that their coach discussed concussions. Additionally, 32% reported receiving a handout, and 23% said their coach had sent them an email or had them watch a video in the past 12 months. Overall, 58% of adolescent athletes reported that their coach discussed or provided information about concussions. More youth athletes who participated in school sports (65%) reported receiving this information, compared to athletes who only participated in non-school sports competitions (39%). About half of youth athletes indicate that they have an athletic trainer during training (55%) or competitions (55%). Youth athletes who participated in school sports were more likely to report having access to athletic trainers (72%) than those who participated on non-school sports teams (49%). Of youth athletes who always/sometimes had an athletic trainer, 63% reported that the coach talked to them about concussions, compared to 24% of youth athletes who rarely or never had access to athletic trainers.

Viewpoints

Four in 10 athletes report that their coaches do not discuss concussions or provide concussion information. The authors found that access to an athletic trainer can improve communication between coaches and youth athletes. It would be interesting to know if the athletic trainer increases the amount of communication as they provide resources for the coaches to share with athletes. It would be helpful to understand how athletic trainers can improve a coach’s concussion communication with athletes. Furthermore, this study focused on whether the coach provided information, and not on the quality of that information. It would be interesting to know how well the education worked. Coaches without access to athletic trainers may provide concussion information to the athletes, but the athlete does not remember it because it was not helpful.

Clinical implications

We must encourage coaches to consistently educate athletes about concussions to improve reporting behavior among youth athletes. In addition, sports trainers have a positive influence on communication between coach and youth. So when we encourage administrators to hire full-time athletic trainers, we can remind them that athletic trainers can help coaches better communicate about concussions and other injuries with their athletes.

Questions for discussion

Are you trying to get coaches to talk to the athletes about concussions? If so, have you seen better results in communication, knowledge and reporting behavior?

Longitudinal changes in youth baseball batting based on body rotation and separation | BMC Sports sciences, medicine and rehabilitation
Attendees

We initially recruited 230 junior baseball players from six teams in Tokyo, Japan in April 2018. The inclusion criteria were males between 6 and 12 years old. The exclusion criteria were injury and illness that prevented the participant from taking measurements. Participants were divided into age groups during the baseball season according to little league eligibility rules – players were classified by age as of July 31 of a given year. Subsequently, the period up to and including July 31 of the second year of primary school was defined as Under 8 (U8), and then the period was divided by year up to and including U13. They played and practiced baseball at least twice a week (Saturday and Sunday) for 3 to 6 hours. Before the study, all participants completed a data questionnaire that asked for the following information: birth, age when they first started playing baseball, and the side they hit. In addition, all participants and their guardians were given a detailed explanation of the experimental procedures and risks of the study before any measurements were taken. In addition, written informed consent was obtained from all participants and their guardians who agreed to the study. This study was approved by the Ethics Committee of Waseda University (No. 2018 − 208).

Batting procedure

Testing was conducted between 9:00 AM and 4:00 PM on an outdoor baseball field maintained under standard environmental conditions. In addition, testing took place between January and March, spread over 4 to 6 days per season. First, we measured the participant’s height and weight while wearing clothes. Then, without shoes on, height was measured to the nearest 0.1 cm without shoes on using a stadiometer (YG200DN, Yagami Co., Nagoya, Japan); and weight was measured to the nearest 0.1 kg using a digital scale (BC622, TANITA Co., Tokyo, Japan). The hitting test was then performed after simple warm-up exercises including dynamic stretching, jogging, light throwing and swinging for approximately 20 minutes. Each participant received unreflected white markers on the top of the head, both lateral acromion points, and the anterior and superior iliac spines. The trial involved toss batting with an automatic toss machine (FTM-240; Field Force Company, China). The toss machine was placed 0.7 m from the center of home plate on the opposite side of the batter and 1.1 m toward the pitcher; it was positioned to launch diagonally in front of the batter. The height of the throwing machine was adjusted to the participant’s height as follows: 45% of the height minus 52.5 cm. Then, after one practice trial, actual testing was performed twice and the hitting motion was recorded at 240 Hz with three high-speed cameras (Ex-100PRO, Casio Co., Tokyo Japan) placed on the side, back, and front of the hitter (oblique). The environment of the impact test environment was shown in Figure 1.

figure 1

Environment of batting test (in case of left-handed batsman)

In addition, swing speed, a component of hitting performance, was measured using a Zepp sensor (ZEP-BT-000002; Zepp Company, Cupertino, California, USA), which has been shown to have high reliability (ICC, 0. 88). [13]and indicated that it correlates moderately to strongly with data analyzed by 3D motion tracking [14]. Participants were allowed to retry the hitting test if they missed the ball while swinging or made timing errors. During the batting test, participants used the bat they would normally use in baseball practice and games, and consistently used the same bat throughout their trials. Data were collected from the highest swing speed test.

Variables

The rotation angles of the head, trunk, pelvis and arm direction in the horizontal plane during the stroke movement and the separation angle between each segment, the amount of head movement and the step width were analyzed by manual digitizing using a motion analysis. system (Frame-Dias V; DKH, Tokyo, Japan). In addition, we visualized the body markers attached to the head, both the lateral acromion points, the anterior and superior iliac spines, the nose, the toes and the midpoint between both hands on the screen using a digital format. Then, three-dimensional coordinates were obtained using the direct linear transformation method [15], and the right orthogonal reference frame was defined as the X-axis, Y-axis, and Z-axis. The Y axis was directed from the pitcher’s mound to home plate, and the Z axis indicated a vertical direction (bottom to top). Furthermore, the X-axis was defined as the cross product of the Y-axis and the Z-axis. For calibration, posts with nine markers (from 0 to 2.0 m at 25 cm intervals) were placed vertically in a 4 x 4 grid at 40 cm intervals (the standard errors were as follows: x = 0.22 cm; y = 0.28 cm; z = 0.34 centimeter). From the beginning to the end of the at bat, a recording of the calibration points was performed using the three high-speed cameras. The analysis data was collected at five points: stance, load, foot contact, front swing and ball contact. Stance and foot contact were defined as the point of the toe of the stepping leg on the Z axis at which the Z axis value began to increase in a positive direction. In addition, load and foreswing were defined as the midpoints between stance and foot contact and between foot contact and ball contact, respectively.

All rotation angles were calculated using values corresponding to spaces in global coordinates, because batting is an operation initiated by responding to a thrown ball and is defined as the projected angle on the horizontal plane relative to the X axis ( Fig. 2). Additionally, the rotation angles were set as positive/negative relative to the pitcher/catcher.

Fig. 2

Definitions of rotation and separation variables

The variables analyzed in this study and their definitions are as follows:
- Head rotation: the angle between the head vector (top of the head to the nose) and the X-axis.
- Upper torso rotation: the angles between the upper torso vector (through the center of both acromions and perpendicular to the line joining both points) and the X-axis.
- Arm direction: the angle between the hand vector (center of both acromions to a point between both hands) and the X-axis.
In addition, the separation angle was expressed as the difference between each rotation angle, and the separation between head and upper trunk was calculated by subtracting the head rotation from the upper trunk rotation. In addition, the separation between the torso and arms was calculated by subtracting the rotation of the upper torso from the arm direction. The upper to pelvic separation was calculated by subtracting the rotation of the upper torso from the rotation of the pelvis. The linear head movement distance (head movement) from stance to foot contact and foot contact to ball contact was calculated as the resulting displacement of the top of the head. Finally, stance widths during stance and foot contact were calculated as the distance between the toes.

static analysis

Statistical power analysis was performed to estimate the sample size. For this study, we needed more than twelve players to perform a comparison between the three groups with 80% power, an alpha of 0.05. and a partial η of 0.14. Seventy-seven baseball players who met inclusion criteria completed three measurements over three seasons. Of these, 17 players formed group 1 (U8 to U10) and 13 players formed group 2 (U11 to U13) (Fig. 3).

Fig. 3

Flowchart of exclusion criteria and final participants

Descriptive statistics (mean ± standard deviation) were performed. After confirming that all data were normally distributed using the Kolmogorov-Smirnov test and confirming homoscedasticity using the Levene test, we performed a one-way analysis of variance (ANOVA) to determine chronological age, height, body weight, years of competition, rotation, and separation comparable. angles, swing speed, head movement and step width at stances, load, foot contact, pre-swing and ball contact between the initial, second and final measurements over three seasons. Additionally, we performed multiple comparisons of the means of the controlled variables using the Bonferroni test. Partial η² was calculated for the effect size of the one-way ANOVA, with values of ≥ 0.01 to < 0.06, ≥ 0.06 to < 0.14, and ≥ 0.14, indicating small, medium, and large effects, respectively [16]. Finally, the alpha level was set at 0.05 and all statistical analyzes were performed using SPSS Statistics 27.0 (IBM, Armonk, New York, USA).

New Shotel™ medical ankle arthrodesis device significantly improves patient quality of life

Reduces time to weight bearing to two weeks from the current six to eight weeks

ATLANTA , Nov. 28, 2023 /PRNewswire/ — Shotel Medical today announced its Shotel™ Ankle Arthrodesis Nail System, which utilizes a novel device design for the treatment of end-stage ankle arthritis. It was used for the first time in Florida last month during a procedure in Delray Beach. Two weeks postoperatively, the patient was weight-bearing with the use of a CAM walking shoe, a significant improvement over the six- to eight-week time to weight-bearing offered by traditional ankle arthrodesis systems.

The patented Shotel Nail System, manufactured and distributed by BioPro Implants, differs from traditional ankle arthrodesis devices because its unique curved design allows for a minimally invasive approach with very small incisions. It is designed to achieve fusion at the tibiotalar joint while allowing unrestricted motion at all other joints. This benefits the patient with faster healing, faster recovery and faster loading. End-stage ankle arthritis is becoming increasingly common and can lead to significant physical disability. There are an estimated 50,000 new cases of ankle arthritis in the US each year¹

“We designed our ankle fusion nail system so that patients have smaller incisions, allowing them to heal faster and function much earlier, giving them a better quality of life. The improvement in time to weight bearing for the patient is meaningful,” said Christopher Weathers, Chief Commercial Officer. “We are pleased to see our Shotel nailing system gaining traction among surgeons across the country. So far, 24 operations have been performed with it.”

Kevin Palmer, DPM, dual board certified podiatrist from Boca Raton and Delray Beach, FL, who performed the procedure, said, “The patient presented with progressively worsening ankle disease and pre-existing structurally compromised hardware. The new design of the Shotel Nail System gave me confidence that it would be stable and would hold up over the long term. During the procedure, after I removed the patient’s current hardware, the Shotel Nail System was inserted smoothly, with a smaller incision and a much less invasive approach than traditional ankle fusion systems. I also like that it provides multiple layers of compression, which is needed at the fusion site to speed healing.

“I cannot emphasize enough how important it is that the patient started walking with a CAM walking shoe within two weeks,” added Dr. Palmer added. “This will be a game changer – and life changing – for many patients in the future.”

DISC Surgery Center in Newport Beach is now enrolling patients in a clinical trial of artificial disc replacement

Drs. Ali H. Mesiwala and Grant D. Shifflett participate in the pivotal two-level study of the safety and effectiveness of the Orthofix M6-C™ artificial cervical disc compared to anterior cervical discectomy and fusion.

NEWPORT BEACH, Calif., Nov. 28, 2023 /PRNewswire/ – DISC Surgery Center of Newport Beach (“DISC”), committed to supporting research vital to the field of spine care, has announced its participation in a clinical trial to artificial disc replacement and is now enrolling qualified patients. Candidates may include patients between the ages of 18 and 75 who have been told they need cervical (neck) surgery at two consecutive levels (among other requirements).

Drs. Ali H. Mesiwala and Grant D. Shifflett – both board-certified, fellowship-trained spine surgeons at DISC – join other experts at approximately 30 clinical sites participating in this study across the country. The primary objective of the study is to evaluate the safety and effectiveness of the Orthofix M6-C™ artificial cervical disc (already FDA-approved for single-level surgery) in patients with contiguous symptomatic bilevel cervical radiculopathy, with or without umbilical cord compression. The results will then be compared with those in patients undergoing anterior cervical discectomy and fusion (ACDF).

Artificial disc replacement surgery is very similar to ACDF surgery. Both procedures remove the damaged disk. However, when the damaged disc is removed to replace the disc, the space between the vertebrae is filled with a specialized implant called an artificial disc, instead of a bone graft. The artificial disc is designed to restore the distance between the vertebrae while still allowing some movement.

With its track record as a national leader in outpatient spine and its team’s extensive experience performing advanced motion maintenance techniques, DISC is ideally positioned to participate in such research.

“The DISC Surgery Center in Newport Beach has placed more than 3,000 cervical discs since 2018 and we are well versed in the motion-preserving qualities of the surgery,” said Dr. Mesiwala. “I think it is important to stay actively involved in research to improve patient care, so I wanted to be part of a study that will improve our learnings and discoveries.”

Dr. Shifflett added, “As pioneers in minimally invasive spine surgery and techniques, we always welcome the opportunity to advance the field while informing the treatment options available to patients.”

Non-arthritic hip pain with Keelan Enseki

Hip pain is common in athletes, especially in sports such as ice hockey.

Non-arthritic hip pain includes a variety of intra-articular diagnoses commonly seen in these athletes that are not directly related to osteoarthritis. These include dysplasia, bony changes, femoroacetabular impingement, labral tears, and more.

A recent clinical practice guideline on this topic was published in JOSPT to help us. In this episode, I talk to the lead author, Keelan Enseki, about the CPG findings.

Show notes

Keelan works at the Rooney Center for Sports Medicine at the University of Pittsburgh Medical Center. He currently serves as director of clinical practice innovation and administrative director of physical therapy residency programs. Keelan is also an adjunct professor at the University of Pittsburgh. In these roles, he divides time between clinical practice, teaching, research/writing, and clinical program design. His clinical interests focus on the nonoperative and postoperative care of individuals with injuries to the hip region. These interests are also represented through collaboration with the Orthopedic and Sports Physiotherapy Academies and the International Society of Hip Arthroscopy (ISHA).
