| Abstract: | Arthroscopic approaches to the femoropatellar joint were developed to determine their usefulness for evaluation and surgical treatment of osteochondritis dissecans. It was found that the articular cartilage of the lateral trochlear ridge, medial trochlear ridge, intertrochlear groove, patella, and the lateral and medial reflections of the joint capsule could be examined from an infrapatellar arthroscopic portal. The suprapatellar pouch could be examined partially. Lateral and medial instrument portals were evaluated to determine the accessibility of the lateral and medial trochlear ridges of the femur in the areas where osteochondritis dissecans lesions frequently occur. Sliding the arthroscope sleeve beneath the patella when entering the joint was associated with iatrogenic cartilage lesions. A new technique that directed the arthroscope lateral to the lateral trochlear ridge eliminated iatrogenic cartilage damage. |
