Osteochondritis dissecans of the knee is an acquired joint disease, characterized by focal ischemic necrosis of the subchondral bone and can progress to a partial or complete separation of an osteochondral fragment (unstable flap) [1]. This joint pathology most often affects young patients. Imaging plays a crucial role in the diagnosis of osteochondritis dissecans of the knee and also helps to rule out certain differential diagnoses, notably insertional tendinopathies and osteonecroses [1]. We report the case of a 31-year-old patient who consulted for chronic knee pain with limitation of knee flexion and extension. Standard knee radiography showed subchondral lucency of the inferomedial part of the left femur, and the knee MRI was consistent with stage III osteochondritis dissecans of the knee. The patient underwent surgical refixation, and the postoperative course was uncomplicated.
