Osteochondrosis dissecans is a spontaneous or posttraumatic necrosis of articular surfaces of not definitive proved etiology. These lesions are seen on radiographs as fragmentations of the subchondral bone or as bony lesion. The presence of articular lesions and non attached fragments is useful concerning therapeutic procedure. The current status of magnetic resonance imaging (MRI) was assessed in 20 patients and correlated in 10 patients with arthroscopic findings concerning classification system. The value of MRI is in indirect detecting cartilage lesions based on signal intensity changes. In the majority of cases the extent of the lesion can exclusively be evaluated by arthroscopy. Based on these results MRI is useful in evaluating articular surface lesions and of assistance in clinical decision making.
