Introduction

Patellofemoral dysfunction affects 25 % of the general population.3 The most common etiology is abnormal patellar tracking or patellar alignment. Causes can be from biomechanical abnormalities of the lower extremity, acute or chronic injuries to the knee joint and/or weak knee joint musculature. It is important for the mechanism of this dysfunction to be identified and treated so a specific rehabilitation program can be prescribed.
Mechanism of Injury The first mechanism, which seems to be the most detrimental, is the affects of Tibiofemoral Osteoarthritis (TF OA) and Patellofemoral Osteoarthritis (PF OA). In both cases of OA, a few signs and symptoms would be grinding, pain with extension and flexion of the knee and stiffness. These signs and symptoms may also be a product of overuse.
