We performed arthroscopy in 8 patients with lateral ligamentous injury of the ankle joint and evaluated intra-articular lesions. Osteochondral lesions were observed at 11 sites in 7 of the 8 patients. Of the 11 sites, 5 were present in the medial tibial cartilage and 3 in the medial talar dome. Synovial proliferation was observed in 6 of the 8 patients. Other diagnostic imaging methods performed before arthroscopy had demonstrated intra-articular lesions in only 1 patient. Three of the 7 patients showing Intra-articular lesions had ankle joint pain probably due to these lesions. In the treatment of lateral ligamentous injury of the ankle joint, the presence of such intra-articular lesions should be considered.
