The initial pain may resolve following an ankle sprain or fracture but then returns; Pain is usually worsened by activity; Swelling, instability, and locking of the ankle joint; Osteochondral lesions happen more frequently in the younger athletic population Diagnosing Osteochondral Lesion of the Talus Osteochondritis dessicans. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. The presence of an osteochondral lesion may initially go undetected and may manifest many months after the initial ankle injury. When blood supply to the area at the end of your bone is cut off, a condition known as osteochondritis dissecans may develop, also called talus osteochondral lesions. This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL). Most classification systems are based on lesion descriptions by Berndt and Harty ( 2 ): incidence 69% of ankle fractures; 70% of ankle sprains; 10% are bilateral The aim of this study was to summarize all eligible studies to compare the effectiveness of treatment strategies for osteochondral defects (OCD) of the talus. The osteochondral lesion can be defined as an area with damaged cartilage at the level of a joint. The following areas are most often affected by the osteochondral lesion: condyle of the femur (often seen), head of the humerus, talus and elbow capitellum.

The most common sites are the posteromedial (53%) ( Fig. focal injuries to the talar dome with variable involvement of the subchondral bone and cartilage resulting in osteochondral lesion of the talus (OLT) may be caused by traumatic event or result of repetitive microtrauma; Epidemiology . Background and purpose - The frequency of progression of osteoarthritis and persistence of symptoms in untreated osteochondral lesion of the talus (OCL) is not well known. Electronic databases from January 1966 to December 2006 were systematically screened. We report the outcome of a nonoperative treatment for symptomatic OCL. Osteochondral lesions of the talus are a reasonably infrequent cause of long-standing ankle pain and stiffness and are often the result of a severe ankle sprain type injury. This will create a cup-like lesion in the central to posterior aspect of the talus with more bone involved than lateral lesions. These are two other names for this condition affecting both the bottom of the ankle bone (talus) and overlying cartilage. The affected bone and its covering of cartilage may stay in place and cause no symptoms. What is the osteochondral lesion?
