WHAT IS A TALAR DOME LESION?

A Talar Dome Lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. These lesions are also known as osteochondral defects (OCDs). A talar dome lesion can be caused from a sudden ankle injury such as a severe sprain or from repetitive microtrauma. Symptoms can include chronic deep ankle pain, clicking or catching sensation in the joint, giving out of the ankle, and swelling. Diagnosis is based on clinical exam, past history, and imaging. Commonly advanced imaging is needed such as MRI to further evaluate. Conservative management includes immobilization in a CAM boot or cast, physical therapy, anti-inflammatory medications, and/or bracing. Surgical management may be needed based on the severity and/or chronicity of the lesion.
