Traumatic Maladies of the Extensor Mechanism

Extensor mechanism injuries can occur in patients of all ages. An understanding of the biomechanics of the patellofemoral joint is essential in diagnosing and treating these conditions. Identification of a mechanical derangement is necessary to correct the underlying cause of the patients complaints. A distinction must be made between bone and soft-tissue injury, and that between acute and chronic injury. There are many causes of extensor mechanism injuries that may be discussed. This chapter will focus on four principal extensor mechanism injuries: (1) patellar and quadriceps tendinitis, (2) quadriceps rupture, (3) patellar tendon rupture, and (4) patellar fractures.
