A Biomechanical Therapy Program for Patients after Total Knee Arthroplasty

Researchers have found that poor postoperative outcomes in pain and function are associated with poor loading patterns on the knee joint, specifically high knee adduction moment, high knee flexion moment and low knee extension moment. These pathological loading patterns are usually present in these patients prior to surgery and are retained after surgery. With time these loading patterns will lead to degradation of the TKA implant with time in a similar pattern to the way the natural knee joint is degraded. This may explain the high risk for revision surgery over the first decade postoperatively.
