Knee OA in amputees: Biomechanical and technological considerations

The risk of knee osteoarthritis in the intact limb of longtime unilateral amputees is much higher than in non­amputees, and the range of potential contri­buting factors is even more complex. Optimizing prosthetic fit and function, in addition to more conventional OA interventions, can help address gait issues that contri­bute to knee joint degeneration.

Foot posture, orthoses, and patellofemoral pain

Putting prehab to the test highlights inconsistencies

The growing popularity of prehabilitation contrasts with mixed findings in the lower extremity literature: Specifically, the approach seems to be more effective in patients undergoing anterior cruciate ligament (ACL) reconstruction than those undergoing hip or knee replacement.
