Abstract
Acute, primary patellar dislocation is a common injury for which no standard treatment has yet been established.The lack of success with conservative management has led many surgeons to recommend early operative intervention. Although surgical procedures have effectively reduced the rate of redislocation, many patients still fail to achieve satisfactory outcomes because of persistent anterior knee pain and continued subluxation. Recent studies have provided a better understanding of the pathoanatomy associated with acute patellar dislocation, enabling surgeons to select techniques that will more appropriately address the essential anatomic lesions of this injury. Restoration of extensor mechanism anatomy should lead to more successful results with fewer adverse outcomes. In this article, the authors briefly review the natural history of acute patellar dislocations and describe their approach for evaluation and management, with emphasis on acute surgical repair techniques.
