Scientific basis of extensor mechanism disorders.
The authors discuss the pathomechanics of abnormal patellar tracking and excessive patellofemoral contact force that results in patellofemoral pain, chondromalacia, and patellofemoral arthrosis. An understanding of the pathomechanics implies a rational approach to treatment that includes methods to correct the tracking problem and reduce the load on the patellofemoral joint.
