Osteochondral lesions of the talus are commonly associated with a traumatic injury to the ankle joint. This commonly occurs after an ankle sprain where the two bones hit against each other, causing a piece of cartilage and bone to chip off inside the ankle. Osteochondral lesion of the talus, also known as OLT, is a disorder, which consists of a section of damaged cartilage. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. BACKGROUND: Autologous osteochondral transplantation (AOT) has been shown to be a viable treatment option for large osteochondral lesions of the talus. The presence of an osteochondral lesion may initially go undetected and may manifest many months after the initial ankle injury. Osteochondral lesion of the talus (OLT) is a broad term used to describe an injury or abnormality of the talar articular cartilage and adjacent bone. There is also a bone on top of the talus. When planning the treatment of osteochondral lesions of the talus, it is important to evaluate the articular cartilage to distinguish between stable and unstable lesions (1,2).Radiography cannot directly depict the cartilage surface ().Both magnetic resonance (MR) imaging and ankle arthroscopy are excellent tools commonly used to evaluate ankle cartilage (3 –5).
