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.”

CHICAGO, Nov. 27, 2023 /PRNewswire/ — Stronger quadriceps muscles, compared to the hamstrings, may lower the risk of total knee replacement, according to research presented today at the annual meeting of the Radiological Society of North America (RSNA). Researchers said the findings could inform strength training programs for people with advanced knee arthritis.
Advanced knee osteoarthritis is a leading cause of pain and disability worldwide. In the US alone, 14 million adults have symptomatic knee osteoarthritis, and more than half of diagnosed patients are expected to eventually undergo total knee replacement surgery.
Although stronger muscle groups are generally thought to be associated with a lower rate of total knee replacements, their relative importance is not well established. Of particular importance is the relationship between the extensors and the hamstrings, the two main muscle groups in the knee.
The extensors, the muscles at the front of the thigh, commonly called the quadriceps, are the strongest muscle group in the body and have a vital influence on walking, other activities and biomechanics. The muscles around the back of the thigh, known as the hamstrings, are responsible for the extension of the hip and flexion of the knee, making them equally essential for physical activity.
“The two muscle groups act as opposing forces, and the balance between them allows for a wide range of activities while protecting the knee joint,” says lead study author Upasana Upadhyay Bharadwaj, MD, of the University of California, San Francisco (UCSF). “An imbalance, among other factors, leads to a change in biomechanics, resulting in the progression of osteoarthritis.”
Dr. Upadhyay Bharadwaj and colleagues evaluated thigh muscle volume in 134 participants in the Osteoarthritis Initiative, a nationwide study sponsored by the National Institutes of Health. They compared 67 patients who underwent total knee replacement of one knee with 67 control participants who did not undergo knee replacement. The cases and controls were matched on variables such as age and gender.
The researchers obtained 3T MRI of the thigh at the time of surgery. They also evaluated MRI findings two years and four years before surgery. They used a previously trained deep learning model to segment and calculate the volumes of the muscles of the thigh – measurements that are difficult to calculate manually.
When comparing patients who had undergone total knee replacement with the control group, a higher ratio of quadriceps to hamstring volume was significantly associated with a lower likelihood of total knee replacement. Higher hamstring and gracilis volumes, a long, thin muscle on the inside of the thigh, were also associated with a lower likelihood of total knee replacement.
“Our research shows that in addition to strong individual muscles, larger extensor muscle groups – compared to hamstring muscle groups – are significantly associated with a lower likelihood of total knee replacement surgery within two to four years,” said Dr. Upadhyay Bharadwaj.
The study results have implications for both the interpretation of imaging studies and clinical management. The results suggest that training programs that strengthen the quadriceps in relation to the hamstrings may be beneficial.
“Although we assume that total muscle volume is important as a surrogate marker of muscle strength, the relationship, and therefore balance, between the extensor and hamstring muscles may be more important and significantly associated with a lower likelihood of total knee replacement,” Dr. Upadhyay Bharadwaj said.
Although the study focused on people with arthritis, the findings could also help inform strength training for a broader segment of the population.
“While these results are essential for targeted therapy in a population at risk for osteoarthritis, even the general public can benefit from our results by preventively incorporating appropriate strengthening exercises,” said Dr. Upadhyay Bharadwaj.

Higher concussion rates following COVID-19 infection in high school athletes.
Bullock GS, Emery CA, Nelson VR, etc. al, Br J Sports Med2023; [epub ahead of print]. two: 10.1136/brjsports-2022-106436.

Take home message
Athletes who tested positive for a COVID-19 infection were more likely to suffer a concussion within 60 days of recovering from the infection than athletes who did not contract COVID-19.
Background
COVID-19 affects the respiratory, cardiovascular and nervous systems. In some cases, COVID-19 can lead to long-term consequences (e.g. impaired cognition). It is currently unknown whether COVID-19 infection affects the risk of sports-related concussions.
Study aim
Bullock and colleagues completed a prospective cohort study to compare concussion rates between high school athletes who recently tested positive for COVID-19 and those who did not.
Methods
The authors recruited athletes from high schools in six states. A certified athletic trainer recorded all cases of COVID-19 infection or concussion. If an athlete reported COVID-like symptoms or had an elevated temperature during a daily screening, the athletic trainer administered a COVID test. The research team also recorded when an athlete participated in a training or competition. The authors focused on the number of concussions within 60 days after an athlete returned to play following a COVID-19 infection. All data was recorded in the Players Health Rehab system, including demographic information, sports and illness data for all athletes.
Results
A total of 72,522 athletes participated in high school sports at the affected school during the 2020-2021 school year. Of these athletes, 430 had COVID-19 infections. Of the athletes with a COVID-19 infection, 32 had a concussion, and 1,241 athletes without COVID-19 had a concussion. An athlete with a history of COVID-19 was approximately 3 times more likely to suffer a concussion within 60 days of returning to play than an athlete without COVID-19.
Viewpoints
Overall, the authors found that prior COVID-19 infection increased the risk of concussion during the first 60 days after recovery from COVID-19. Therefore, the effects of a COVID-19 infection may linger after returning to play. Knowing whether this applies to other sports-related injuries would be interesting. Additionally, learning why these athletes are at greater risk for concussion (e.g., deconditioning, persistent symptoms) can help us develop prevention strategies and make informed decisions about when and how to release an athlete to play following a COVID-19 infection.
Clinical implications
Doctors should explain to patients with COVID-19 that they may experience lingering effects that predispose them to concussion. We need to help the patient make an informed decision about when to return to play after COVID-19 infection. Once an athlete returns, doctors should monitor these patients for concussions.
Questions for discussion
What other measures have you implemented in your clinical practice to monitor athletes after COVID-19 infection? Is a COVID-19 infection something you are currently documenting?

Causes of Knee Pain
Injuries Affecting the Knee
Knee injuries can involve various structures around the knee joint, such as ligaments, tendons, bursae, bones, and cartilage. Some common knee injuries are:
ACL injury: A tear in the anterior cruciate ligament, which connects the shinbone to the thighbone, often occurs in sports that require sudden directional changes like basketball or soccer.
Fractures: Knee bones, including the kneecap, may break due to falls or vehicle accidents. Osteoporosis can also lead to knee fractures from minor missteps.
Torn meniscus: The meniscus, the cartilage cushioning between the shinbone and thighbone, may tear if the knee is suddenly twisted while bearing weight.
Knee bursitis: Injuries may cause inflammation in the knee bursae, the fluid-filled sacs that enable smooth movement between tendons, ligaments, and the knee joint.
Patellar tendinitis: This refers to the irritation and inflammation of tendons attaching muscles to bones, particularly the patellar tendon connecting the kneecap and shinbone. It often occurs in runners, skiers, cyclists, and people involved in jumping sports.
Mechanical Issues
Mechanical problems causing knee pain include:
Loose body: Detached bone or cartilage fragments floating in the joint space can obstruct knee joint movement, akin to a pencil caught in a hinge.
Iliotibial band syndrome: Tightening of the iliotibial band, which extends from the hip to the outer knee, can cause rubbing against the thighbone. Distance runners and cyclists are prone to this condition.
Dislocated kneecap: The kneecap can slip out of place, typically to the knee’s outside. In some instances, the dislocation remains visible.
Hip or foot pain: Compensating for pain in the hips or feet by changing one’s gait can place extra stress on the knee joint, leading to pain.
Forms of Arthritis
Various types of arthritis can cause knee pain:
Osteoarthritis: This wear-and-tear condition results from the knee cartilage’s deterioration due to use and age.
Gout: Occurs when uric acid crystals accumulate in the joint, typically affecting the big toe but also the knee.
Pseudogout: Often mistaken for gout, this condition stems from calcium-containing crystals in the joint fluid. The knee is the most frequently affected joint.
Septic arthritis: An infection in the knee joint may lead to swelling, pain, redness, and fever. It can quickly damage the knee cartilage, requiring urgent medical attention.
Additional Issues
Patellofemoral pain syndrome (PFPS) refers to discomfort between the kneecap (patella) and underlying thighbone (femur). It involves abnormal forces transmitted through the patellofemoral joint which is the articulation between these two structures. PFPS commonly affects certain populations, especially athletes who overloaded their knees through repetitive overuse from sports.
The main culprit causing PFPS is maltracking or dysfunction of the kneecap as it glides up and down in a groove on the femur during knee bending. This maltracking indicates a biomechanical imbalance, often from tight muscles or anatomical misalignment pulling the cap sideways. This leads to increased pressures on the back of the patella and the adjacent cartilage, triggering pain.
PFPS frequently develops in young active adults, particularly females, who have naturally higher “Q angles” – an anatomical measurement of kneecap positioning. It also occurs in some older adults for whom the cartilage under the kneecap has worn away significantly due to arthritis, causing bone-on-bone grinding. These groups appear predisposed towards developing knee pain from the aftermath of abnormal patellofemoral mechanics.
Besides overuse from sports and vulnerable anatomy, other PFPS triggers involve sudden increases in loading too quickly. The muscles stabilizing the patella require adaptations to control loads safely. When demands exceed abilities, the kneecap tracking suffers. Additionally, poor movement patterns such as unbalanced squatting or jumping/landing with knock knees induces patellofemoral compression. Often tight quadriceps, IT bands and calves paired with weak hips/glutes contributes to dysfunction.
Several targeted interventions aim at conservatively realigning the patella, strengthening deficient stabilizers, restoring ideal tracking and alleviating compression forces causing PFPS. Using braces, taping, customized exercise corrections and gait pattern retraining are common initial tactics under therapist guidance to calm pain and prevents recurrences. In some cases of refractory PFPS or significant arthritis, surgical options to release or reshape overtightened tissues or resurface damaged articulations provide longer term solutions.
Prevention Strategies for Knee Ligament Injuries: Professional Tips
Knee ligament injuries are common among athletes and can be a frustrating setback for anyone who enjoys an active lifestyle. The knee joint is one of the largest and most complex joints in the body, making it vulnerable to various types of injuries. Understanding and identifying knee ligament injuries is crucial to prevent further damage and promote quick recovery.
The most common knee ligament injuries are the anterior cruciate ligament (ACL), medial collateral ligament (MCL), posterior cruciate ligament (PCL), and lateral collateral ligament (LCL). These injuries can occur due to direct trauma, such as contusions and strains, or from indirect trauma, such as sudden changes in direction. Symptoms of knee ligament injuries include pain, swelling, inflammation, and joint laxity. In this article, we will discuss five prevention strategies for knee ligament injuries to help maintain knee stability and prevent knee instability.
professional tips for prevention strategies to help avoid knee ligament injuries:
Category
Tips
Strength & Flexibility Training
– Emphasize hamstring, glute, quad, hip & core exercises<br>- Ensure muscle imbalances are addressed<br>- Use proper form/technique to prevent overstress
Movement Control & Balance

Confidence in knee stability paired with caution towards unsafe mechanics allows for safer progression. Expert guidance tailoring programs is key for best injury deterrence.
Key Takeaways
Understanding the anatomy of the knee joint and identifying knee ligament injuries can promote quick recovery.
Direct and indirect trauma can cause knee ligament injuries, leading to pain, swelling, inflammation, and joint laxity.
Understanding and Identifying Knee Ligament Injuries
Knee ligament injuries are common among athletes and individuals who engage in physical activities that require jumping, pivoting, or sudden changes in direction. In this section, we will discuss the common types and causes of knee ligament injuries, how to identify symptoms and diagnose the injury, treatment and rehabilitation options, and the role of sex and age in knee ligament injuries.
Common Types and Causes
The most common types of knee ligament injuries are the anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries. The ACL is usually injured during non-contact activities such as landing after a jump or sudden stops and changes in direction. On the other hand, the MCL is usually injured from a direct blow to the outer side of the knee, such as when playing football or hockey.
Symptoms and Diagnosis
The symptoms of knee ligament injuries include pain, swelling, bruising, and instability. The diagnosis of knee ligament injuries is usually made through a physical exam and imaging tests such as MRI or X-rays. It is important to seek medical attention if you experience any of these symptoms.
Treatment and Rehabilitation
The treatment and rehabilitation of knee ligament injuries depend on the severity of the injury. Treatment options include rest, ice, compression, and elevation (RICE), physical therapy, and surgery. Rehabilitation includes exercises to improve range of motion, strength, and mobility. It is important to follow the guidance of a physical therapist or orthopedic surgeon to ensure proper recovery.
Role of Sex and Age
Research shows that females are more prone to knee ligament injuries than males due to differences in anatomy, form, and hormones such as estrogen and relaxin. Additionally, age plays a role in knee ligament injuries, with individuals over 50 years old being at a higher risk due to decreased muscle strength and flexibility.
Sports and Injuries
Knee ligament injuries are common in sports that require sudden stops and changes in direction such as soccer, basketball, and football (soccer). Injury prevention programs that include warm-up, neuromuscular training, and proprioception exercises can reduce the frequency of knee ligament injuries by up to 50%.

Rehabilitation Exercises for Knee Ligaments: Strengthening and Recovery Techniques
As physical therapists, we often see patients with knee ligament injuries. Knee ligaments are strong bands of tissue that connect the thighbone to the shinbone and provide stability to the knee joint. Injuries to knee ligaments can result in pain, swelling, and decreased range of motion. Rehabilitation exercises for knee ligaments can help improve joint stability, reduce pain, and restore function.
Understanding Knee Ligament Injuries is important for developing an effective rehabilitation plan. There are four main ligaments in the knee joint: the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL). ACL and PCL injuries are more common in athletes and can occur during sports that involve sudden stops, changes in direction, or jumping. MCL and LCL injuries can result from a direct blow to the knee or from twisting the knee. Depending on the severity of the injury, surgery may be required to repair or reconstruct the damaged ligament.
In this article, we will discuss 6 Rehabilitation Exercises for Knee Ligaments that can help improve joint stability, reduce pain, and restore function. These exercises are designed to strengthen the muscles that support the knee joint and improve biomechanical function. By following a structured rehabilitation program, patients can improve their recovery and return to their daily activities faster.

Understanding Knee Ligament Injuries
Knee ligament injuries are common among athletes and individuals who engage in physical activities. These injuries can be caused by a wide range of factors, including trauma, overuse, and sports-related injuries. The most common types of knee ligament injuries include anterior cruciate ligament (ACL) injuries, medial collateral ligament (MCL) injuries, and posterior cruciate ligament (PCL) injuries.
Causes and Types of Injuries
ACL injuries are typically caused by a twisting motion or a direct blow to the knee. MCL injuries, on the other hand, are often caused by a direct blow to the outside of the knee. PCL injuries are usually the result of a direct blow to the front of the knee or a hyperextension injury.
Ligament injuries can be classified as either partial or complete tears. Partial tears involve damage to a portion of the ligament, while complete tears involve a complete separation of the ligament from the bone. Overuse injuries, such as tendinitis, can also occur in the knee.
Diagnosis and Assessment
Diagnosis of knee ligament injuries involves a physical examination, imaging tests, and other diagnostic procedures. Physical examination involves assessing the knee for pain, swelling, and instability. Imaging tests such as magnetic resonance imaging (MRI), radiographs, and ultrasound can also be used to assess the extent of the injury.
Treatment Options
Treatment options for knee ligament injuries depend on the severity of the injury. Nonoperative treatment may involve rest, ice, compression, and elevation (RICE), physical therapy, and immobilization. Operative treatment may involve surgery, such as arthroscopy or ACL reconstruction.
Post-Injury Challenges
Post-injury challenges may include pain, swelling, and instability. Rehabilitation is essential for restoring full function and reducing the risk of future injuries.
Understanding the Rehabilitation Process
Rehabilitation is an essential part of the recovery process for knee ligament injuries. The rehabilitation process involves a series of exercises and other interventions designed to improve muscle strength, proprioception, and joint stability.
Specific Rehabilitation Exercises
Specific rehabilitation exercises may include exercises to improve muscle strength, such as knee flexion and extension exercises, as well as exercises to improve proprioception, such as balance training.
Role of Imaging in Rehabilitation
Imaging tests such as MRI and radiographs can be used to assess the extent of the injury and monitor progress during rehabilitation.

Anterior cruciate ligament (ACL) reconstruction is a common surgical procedure for individuals who have suffered a torn ACL. While outcomes have improved dramatically, knee pain and re-injury continue to be concerns during the recovery process. Recent advances in rehabilitation protocols and biomechanical research are shedding light on optimal recovery strategies.
Knee pain following ACL reconstruction arises due to multiple interrelated biomechanical and physiological factors. The initial trauma of surgery triggers an inflammatory response which can lead to fluid buildup, swelling, and stiffness, resulting in pain with movement. This acute inflammatory phase usually lasts 6-8 weeks. Concurrently, muscular imbalances around the knee joint develop, most notably quadriceps inhibition and weakness. The quadriceps muscles play a crucial role in stabilizing the knee joint. When weakened and inhibited after surgery, abnormal forces are transmitted through the joint, exacerbating pain and dysfunction. Finally, biomechanical alterations including asymmetric gait patterns and improper landing mechanics cause further pain. A careful evaluation of all these contributing trigger points through a full physical therapy examination is key to pinpointing the optimal treatment approach.
Causes of Knee Pain
Knee pain following ACL reconstruction arises due to multiple interrelated biomechanical and physiological factors. The initial trauma of surgery triggers an inflammatory response which can lead to fluid buildup, swelling, and stiffness, resulting in pain with movement.
Inflammation
This acute inflammatory phase usually lasts 6-8 weeks.
A 2022 study found that altered walking biomechanics were present even 2 years after surgery, especially in females (Smith et al). These persistent abnormalities highlight the need for rehabilitation focused on normalizing movement patterns.
Effective knee pain management requires a multifaceted rehabilitation program tailored to the individual’s specific deficits and dysfunctions. The priority initially is controlling inflammation through ice, compression, medication, and activity modification. Once pain and swelling have been reined in, restoring full knee mobility is essential for reducing stiffness and dysfunction. Gentle manual therapy techniques and range of motion exercises facilitate this process. As mobility improves, muscular imbalances must be addressed through targeted stretching and progressive strength training, focused especially on reactivating the quadriceps. Finally, movement pattern retraining helps ingrain proper mechanics. Areas to emphasize include squatting, lunging, walking gait, running, jumping and landing. The goal is to eliminate any asymmetries or compensations that could lead to abnormal forces through the joint. Throughout this process, communication with the care team is key to calibrate the program to avoid flare-ups while still stimulating progress.

Optimizing Long-Term Outcomes
Preventing Re-Injury
Due to the high risk of retear after ACL reconstruction, prevention of re-injury is paramount during recovery. Gradually building up strength and then progressing activity in a controlled manner based on specific objective criteria allows tissues to heal while regaining function.
As the graft incorporation stretches beyond 6 months, impact activities can be cautiously integrated. However, pivoting sports may need to wait 9 months or more. Maintaining quadriceps and core strength and allowing the full return of power and agility prior to discharge from therapy ensures the knee can withstand demands of sport. Sticking to activity guidelines, along with smart training periodization can optimize recovery even years after ACL surgery.
