Evaluation and management of osteochondral lesions of the talus in skeletally immature patients.

Osteochondral lesions of the talus (OLTs) are defined as damage to the talar cartilage, with pathological changes in the underlying bone. They include a group of injuries that involve juvenile osteochondritis dissecans (JOCD) and osteochondral fractures of the talus. The etiology of OLT remains not fully clarified but is more common in young and active patients. Treatment strategies for OLTs in skeletally immature populations depend on the magnitude of symptoms, lesion morphology (stability and overlying cartilage integrity), size, nature of the lesion (traumatic versus JOCD), ankle stability, lower extremity alignment, and previous treatment. The aim of this review is to provide an overview of the current evidence for the diagnosis and treatment of OLTs in skeletally immature patients.
