Osteochondritis dissecans is a joint condition whereby part of the bone and its adjacent cartilage lose their blood supply.

It can affect virtually any joint, but it’s most often found in the elbows and knees. The condition most commonly affects males between 9 and 18 years old.

Although the causes of osteochondritis are often unidentified, it can result from mild recurrent injuries or growth disturbances. The symptoms include joint pain, stiffness, and even locking of the joint so that its range of motion is very limited. There is no definitive cure, but the condition can be treated by a variety of means depending on the size and location of the lesion, as well as the age of the patient and the degree of acuteness of the symptoms. Arthroscopic surgery is frequently used as a treatment to remove the loose cartilage and bone tissue from the joint.
