Positives for PFP: Benefits of six-week rehab are retained

Six weeks of lower extremity strengthening in runners with patellofemoral pain (PFP) leads to improvements in pain and function that are retained six months later, regardless of whether the rehabilitation focuses on the knee or the hip, according to research presented in late June at the National Athletic Trainers Association (NATA) annual meeting in Las Vegas.

Barefoot running with nonrearfoot strike pattern may put Achilles at risk

Women who run barefoot with a midfoot or forefoot strike pattern have higher Achilles tendon (AT) loads—and, potentially, a higher risk of tendinopathy—than rearfoot strikers, according to research e-published May 3 in the Annals of Biomedical Engineering.

Study links concussion to increased incidence of lower extremity injury

College athletes who sustain a concussion are almost four times as likely as their counterparts who avoid the brain injury to subsequently injure lower extremity muscles, according to research presented at the 2013 American Medical Society for Sports Medicine conference held in April in San Diego.

Benefits of bracing: Studies find improvement in pain, gait

Studies presented at the 2013 World Congress on Osteoarthritis, held in April in Philadelphia, provide more evidence that knee bracing can improve pain and gait mechanics in patients with knee osteo­arthritis (OA)—improvements that are magnified with increased wear time.

Nonoperated knee remains vulnerable after unilateral total joint arthroplasty

Unilateral total knee arthroplasty (TKA) does not reduce loading in the nonoperated knee, and the resulting asymmetry may help explain why many patients end up undergoing TKA in the contralateral knee within 10 years of the initial procedure, according to an Israeli study presented at the 2013 World Congress on Osteoarthritis.

Adding exercise to diet improves pain, function in overweight knee OA patients

Adding exercise to a dietary program does not significantly increase weight loss or reduce loading in overweight patients with knee osteoarthritis (OA) compared to diet alone, but the addition of exercise is associated with significant improvements in pain and function, according to preliminary results of a large 18-month trial presented in April at the 2013 World Congress on Osteoarthritis.
