Osteochondritis dissecans of the patellofemoral groove in athletes: unusual cases of patellofemoral pain.
Five athletes who developed osteochondritis dissecans in the patellofemoral groove in the course of sports events at high school and college league level are described. They were male athletes complaining of anterior knee pain. When examining young people engaged in violent sports, it is well to remember that they might have osteochondritis dissecans in the patellofemoral groove. Clinically, four of the five patients under discussion were characterized by tight movements of the patella in a direction parallel to its transversal axis. X-ray studies in lateral projections and CT scans provided useful tools for definitive diagnosis, but AP radiography was no help in diagnosis. Release of a tight lateral retinaculum with or without drilling on the degenerated cartilage was effective in the treatment of osteochondritis dissecans of the patellofemoral groove in three of the four patients.
