Subtalar Osteochondral Lesions: Diagnosis, Indications, and Prognosis.

Although most commonly found in the knee, elbow, and talar dome, osteochondral lesions can also be found in the subtalar joint and can occur due to either high or low energy trauma. Diagnosis of these lesions in the subtalar joint is typically confirmed with advanced imaging such as computerized tomography and MRI. Although there are a few published case reports, there is otherwise very limited literature on the prevalence, treatment options, prognosis, or outcomes for patients with osteochondral lesions of the subtalar joint, and thus further research is required in this area.
