It occurs when a small segment of bone begins to separate from its surrounding region due to a lack of blood supply. Osteochondritis dissecans is an idiopathic lesion of subchondral bone. When this damage occurs, what happens is that a fragment of the cartilage comes loose from the bone. An osteochondral ankle defect is a lesion of the talar cartilage and subchondral bone mostly caused by a single or multiple traumatic events, leading to partial or complete detachment of the fragment. It affects both the cartilage (chondro) and the bone (osteo) underneath and most often occurs in the ankle, knee or elbow. Osteochondritis Dissecans (Osteochondral Lesion of the Talus) Authored by Dr. Patrick DeHeer Reviewed by Dr. Kyle Scholnick Osteochondral lesions, also known as osteochondritis dissecans, are areas of damaged bone and cartilage on the surface of the ankle bone (the talus), usually caused by an ankle injury. Osteochondritis dissecans (OCD) of the ankle is the end result of the aseptic separation of an osteochondral fragment of the talar dome with the gradual fragmentation of the articular surface. This bone and cartilage can then break loose, causing pain and possibly hindering joint motion. As a result, the small piece of bone and the cartilage covering it begin to crack and loosen. However, affected people may experience pain, weakness and/or decreased . Osteochondritis dissecans occurs when a piece of bone or articular cartilage separates due to a lack of blood supply.

It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT) or Osteochondritis Dissecans. A history of locking, catching or ankle sprains on multiple occasions is common. It can lead to joint pain with limitation of movement, this can affect daily activities. As osteoarthritis progresses, pain is felt even during inactivity or rest. Osteochondritis dissecans usually develops in just one joint. This can lead to varying degrees of damage to the cartilage of the ankle joint.

OLT can be caused by any twisting-type injury to the ankle if it is severe enough. OCD can be stable, unstable, or completely float away from the ankle joint as a loose bone part in the joint. These include wedge osteotomy, osteochondral grafting, periosteal grafting, perichondral grafting, and articular cartilage allograft transplantation. There is often a history of multiple ankle problems that do not have a clear cause or diagnosis. Lost flexibility and joint movement. Sometimes injuries to the ankle joint are harder to heal because the blood supply to the bones of the ankle is not as abundant as elsewhere in the body. This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL). This guide will help you understand. Osteochondral defects (OCDs) are very localised areas of joint damage which can occur in a number of different joints , not just the ankle. Majority of patients are adolescent or young adult athletes. Most cases of OCD usually follow a twisting injury to the ankle and are actually fractures of the joint surface. See the main osteochondritis dissecans article for a general discussion on this condition, which mostly affects the knees. Osteochondritis is caused by a twisting-type injury to the ankle. If the piece of cartilage and bone remain close to where they detached, they may not cause any symptoms. how OCD develops; how the condition causes problems [2] Osteochondritis Dissecans (OCD Lesions) Osteochondritis Dissecans, also commonly referred to as an osteochondral lesion (OCL) or osteochondral defect (OCD), is a condition in which there is a cartilaginous defect within one of the joints in your foot or ankle. [1] This may result in separation and instability of a segment of cartilage and free movement of these osteochondral fragments within the joint space. Majority of patients are adolescent or young adult athletes. Sometimes it may appear in the ankle or elbow but can happen in any joint.

Osteochondritis dissecans (OCD) of the ankle is the end result of the aseptic separation of an osteochondral fragment of the talar dome with the gradual fragmentation of the articular surface. The "classical" defect involves a disruption of both the bone (osteo) and cartilage (chondral) .They usually occur on the Talus if effecting the ankle joint and are a region where the cartilage and underlying bone have been disrupted. Pain is the primary symptom of osteoarthritis in the ankle joint. Main joints involved include the knee, ankle, and radiocapitellar joint of the elbow. Osteochondritis dissecans occurs at the top of the talus. Majority of patients are adolescent or young adult athletes. OCD is characterized by a loss of blood supply to one or more bones in the ankle, which may result in a fracture or break within the ankle joint. Symptoms include swelling and ankle pain.
