The sprinter’s advantage: Thinking outside the blocks

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?

Publisher’s memo: Embracing change

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.

Out on a limb: Power in practice

Healthcare researchers don’t get a lot of instant gratification. Typically it takes years for a study’s findings to have an impact on clinical practice, and often that doesn’t happen until those findings have been replicated by additional studies.

Pediatric obesity weighs on growing bones, joints

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.

Development of the arch: Functional implications

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.

The evidence for use of gauntlet-style AFOs

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.

Dialysis treatment takes toll on diabetic foot care

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.

ACL reconstruction and risk of knee OA, part 2

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

Fusion vs replacement: Both improve gait, but well short of normal

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).

ATFL repair with any of three methods decreases ligament stiffness, strength

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.

Effects on plantar flexor endurance, power linger after gastroc recession

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.

Bracing affects plantar pressures and inversion, but not most performance tests

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.

Concussion conundrum: Chronic postural deficits elude detection

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 stands out as predictor of future ACL injury risk

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.

In patients with patellofemoral pain, hip weakness may be result, not cause

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.

Arthroscopy attrition: 2002 study changes practice patterns

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.

Bone bruises associated with ligament injuries may predict chondral damage

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.

Soccer training intensity affects levels of biomarker for cartilage degradation

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.
