Articular Cartilage Injuries Associated with Patellar Dislocation
Patellar dislocation and recurrent instability are common and affect predominantly the younger population, especially athletes. Patellar dislocation is often combined with articular cartilage lesions. From bone bruises to large osteochondral fractures, articular cartilage lesions have been reported in as many as 95% after patellar dislocation. Chondral and osteochondral injuries are often associated with acute traumatic dislocation. However, during low-energy patellar dislocation, a lower incidence of osteochondral damage is reported. Recurrent instability can increase articular cartilage lesion severity and increase the risk of joint degeneration and the development of osteoarthritis. Articular cartilage lesions should be treated with fixation or reconstruction of the articular surface. It is important to recognize the underlying predisposing factors for instability and treat them along with the chondral or osteochondral lesions.
