Odd couple: Linking ACL injury and patellofemoral pain

One is an acute injury, the other a chronic condition. But researchers believe it’s no coincidence that anterior cruciate liga­ment injury and patellofemoral pain syn­drome share many of the same risk factors. The next step is to determine if a single intervention can effectively prevent both.

Out on a limb: Amputation ups & downs

Lower extremity practitioners who treat patients with diabetes are finally receiving their 15 minutes of fame. Enjoy it while it lasts. The Centers for Disease Control and Prevention (CDC) finding that nontraumatic lower extremity amputation (NLEA) rates in patients with diabetes decreased by 67% between 1996 and 2008 (see “CDC reports dramatic 12-year drop in diabetic lower limb amputation,” page 15) is unquestionably good news.

Wedge orthoses: A distal slant on knee OA therapy

Most conservative measures to reduce knee adduction moment in patients with knee osteoarthritis involve altering proxi­mal bio­mechanics, but research suggests that similar kinetic changes and pain relief can be achieved with the use of wedged foot orthoses.

Use of eccentric exercise for prevention and rehab

Recent interest has focused on the use of Nordic hamstring strengthening exercises to prevent hamstring injuries in athletes, but evi­dence also supports eccentric exercise for managing tendinopathy and for pre­ven­tion and rehabilitation of anter­ior cruciate ligament injury.

Success of hinged AFOs depends on alignment

Misalignment between the mechanical joint of an articulated AFO and the cor­responding anatomical joint can signifi­cant­ly affect the device’s mechanical properties, particularly resistance and stiffness, which can impair AFO effective­ness and negatively affect proximal joints.

Hip rotation in golfers may determine pathology

Golfers demonstrate significant asym­metries between hips with regard to rotational range of motion and rotational velocity, which can contribute to the development of conditions including low back pain, femoroacetabular impinge­ment, and hip labral degeneration.

Foot-shoe mismatches leave patients at risk

Survey results suggest that at least one-third of individuals at risk for foot pain or diabetic foot ulcers are wearing shoes that are at least one size too big or too small, which can further increase those risks. Proper shoe fit and foot health start with patient education.

Original research: Taping alters ankle biomechanics

This study found that closed basket-weave ankle taping significantly affects ankle range of motion and time to peak vertical ground reaction force, which can have implications higher up the kinetic chain that appear to vary from one indivi­dual to another.
