Abstract

Osteochondral lesions of the talus (OLTs) are the lesions that affect the articular cartilage and the subchondral bone of the talus. Symptoms develop between 6 and 12 months after the index trauma and are associated with degradation of quality of life. Two-thirds of the lesions (73%) are located on the medial part of the talus, 28% of the lesions are posteromedial, and 31% of the lesions are centromedial. Currently, OLT of up to 100 mm<sup>2</sup> can behave in a more indolent condition, and above that area, the defect tends to transmit more shearing forces to adjacent cartilage and is more symptomatic.
