Researchers at The Pennsylvania State University have identified structural characteristics that distinguish the foot and ankle mechanics of trained sprinters from nonsprinters. Are similar underlying variables responsible for the reductions in mobility that affect older adults?

As a father of four, I knew the day would come when one of them would be moving on. As my wife and I watched our eldest son walk across the stage to receive his high school diploma, I was reminded of how fast life moves and how important it is to have a strong network of support to help embrace that change.
Exercise is the standard prescription for obesity. But alterations to joint biomechanics, gait, and anatomical structure in overweight children and teens mean that physical activity comes with its own risks, which practitioners must factor into any clinical recommendations.

Contrary to the conclusions of early research, recent studies suggest that arch height does indeed affect lower extremity function. The biomechanics associated with different arch heights may provide a basis for treatment and prevention of related injuries.

Gauntlet-style ankle foot orthoses offer an alternative to a larger rigid thermoplastic AFO for foot and ankle pathologies requiring more stability or immobilization than a foot orthosis provides. Materials, trim lines, and fabrication techniques can vary to meet different patients’ needs.

A convergence of comorbidities means diabetic patients on dialysis have an even higher risk of foot ulcers and amputation than those without renal disease. The potential for preventing these complications at dialysis centers is too often underappreciated by practitioners.

This two-part series examines the link between ACL injury and the later development of osteoarthritis (OA) and how surgery may strengthen or weaken that link. This second installment explores meniscal damage, proprioception, and what MRI can add to the discussion.

In the Moment: Ankle
By Jordana Bieze Foster
Functional outcomes for total ankle replacement (TAR) in patients with end-stage ankle arthritis appear to match or exceed those of ankle fusion, according to research presented in June at the annual meeting of the American Orthopaedic Foot & Ankle Society (AOFAS).
Three different methods for repairing the anterior talofibular ligament (ATFL) leave the repaired structure significantly stiffer and weaker than an intact ligament, which may have implications for ankle injury rehabilitation, according to research presented in June at the AOFAS meeting.
Tasks requiring plantar flexor endurance and push-off power remain difficult for patients long after an otherwise successful gastrocnemius recession for treatment of Achilles tendinopathy, according to findings presented in June at the AOFAS meeting.
Research presented in June at the annual meeting of the National Athletic Trainers Association shed more light on the biomechanical effects of ankle braces that can help reduce the risk of inversion injury.

Sophisticated laboratory experiments have documented postural control deficits in athletes with a history of concussion, but research presented in June at the annual meeting of the National Athletic Trainers Association (NATA) suggests clinicians may find it difficult to identify similar deficits in concussed athletes once their other symptoms have resolved.
Hip adduction on landing is a significant predictor of anterior cruciate ligament (ACL) injury risk, according to a large prospective study from the University of North Carolina at Chapel Hill, presented in June at the NATA meeting.
A pain-inducing protocol significantly reduces hip extension strength in patients with patellofemoral pain (PFP), suggesting that hip weakness associated with the condition may be a result and not a cause, according to research from the University of Wisconsin-Milwaukee presented in June at the NATA meeting.
In the Moment: Knee OA
By Samantha Rosenblum and Jordana Bieze Foster
The number of knee arthroscopy procedures performed in patients with osteoarthritis (OA) has greatly decreased since the 2002 publication of a high profile New England Journal of Medicine study that questioned the procedure’s effectiveness, according to research from the Cleveland Clinic in Cleveland, OH.
The distribution of bone bruises associated with acute knee ligament injury is consistent with long-term patterns of chondral damage, according to research from the University of Kentucky in Lexington presented in June at the annual meeting of the National Athletic Trainers Association.
Increased exercise duration is associated with elevated levels of a serum biomarker previously found to be an indicator of cartilage damage, according to research from the University of Kentucky in Lexington presented in June at the annual meeting of the National Athletic Trainers Association.
