Today 46 yrs old gentleman MRI left ankle sent to us for reporting, reveal small cystic area 11x11mm on medial half of head of talus involving articular cartilage with mild flattening of talar dome without large surrounding collection suggesting osteochondral lesion (osteochondritis dessicans). OSTEOCHONDRAL LESIONS OF TALUS (OLT) sometimes called OSTEOCHONDRITIS DESSICANS or osteochondral fractures are injuries to the talus (the bottom bone of the ankle joint) that involve both the bone and the overlying cartilage. OLTs can occur after a single traumatic injury or as a result of repeated trauma. Common symptoms include prolonged pain, swelling, catching and/or instability of the ankle joint. Treatment may consist of either non-operative or operative methods. Non-operative treatment is appropriate for certain lesions and usually involves immobilization and restricted weight bearing. This may then be followed with gradual progression of weight bearing and physical therapy. The goal of non-operative treatment is to allow the injured cartilage and bone to heal. Other lesions may be more appropriately treated with surgery. The goals of surgery are to restore the normal shape and gliding surface of the talus in order to re-establish normal mechanics and joint forces. The hope is to minimize symptoms and limit the risk of developing arthritis. Depending on the characteristics and location of the OLT, surgery may done arthroscopically or by opening the skin. Arthroscopy uses a camera and small instruments to view and work within the joint through small incisions. It may not be possible to properly treat certain lesions arthroscopically due to the size or location of the lesion. Treatments may include debridement (removing injured cartilage and bone), fixation of the injured fragment, microfracture or drilling of the lesion, and/or transfer or grafting of bone and cartilage.
