The unstable cartilage rim … A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. [] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. The aim of this study was to summarize all eligible studies to compare the effectiveness of treatment strategies for osteochondral defects (OCD) of the talus. This chapter is adapted from Chao W, Freeland E, Dedini R: Osteochondral Lesions of the Talus in Chou LB, ed: Orthopaedic… Immobilization of the ankle, medications, steroid injections and physical therapy are commonly tried but this often fails to relieve symptoms and surgery may be required. .

The proportion of the patient population treated succes … Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. “Osteo” means bone and “chondral” refers to cartilage. The presence of an osteochondral lesion may initially go undetected and may manifest many months after the initial ankle injury. 70 Patients suffering from these defects typically experience persistent or intermittent deep ankle pain during or after activity. A microfracture technique of osteochondral lesion of the talus is demonstrated. A mid-medial osteochondral lesion of the talus is demonstrated on Fig. [] Although majority may be associated with trauma, some may develop insidiously. Most researchers believe that a traumatic cause plays a pivotal role in the development of a vast majority of OLTs.

Osteochondral lesions of the talus are a reasonably infrequent cause of long-standing ankle pain and stiffness and are often the result of a severe ankle sprain type injury. Osteochondral Repair of Talus: Causes Leading To Osteochondral Lesions. The MRI confirmed osteochondral fracture of the anterolateral talus with mild displacement. The Traumatic Defects. Recommendations to proceed with diagnostic arthroscopy of the right ankle for evaluation of the congruity of the articular surface with possible removal of osteochondral fracture versus repair either arthroscopically or open were discussed in detail. Talar dome lesions are usually caused by … It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). The treatment for an osteochondral defect of the talus is extremely varied and depends on the size of the defect … The University Foot and Ankle Institute is one of the top foot and ankle centers in the world. Anterolateral (2), anteromedial (1), and accessory portals (3) are demonstrated on Fig. Treating osteochondral lesions of the talus can pose challenges and delayed diagnosis due to late presentation after an ankle sprain. Osteochondral Defect of the Talus (OCLT) is a condition that involves the cartilage of the ankle joint – specifically the talus. 20 The treatment of talar OCDs is usually initiated with a nonoperative protocol. : Causes Leading to osteochondral lesions of the subchondral bone and “ chondral ” refers to cartilage is injury.
