Osteochondritis Dissecans
Pronunciation: OS-tee-oh-kon-DRY-tis dis-SEH-kans
A joint condition where bone underneath cartilage dies due to lack of blood flow, causing cartilage and bone fragments to loosen.
Full Definition
Osteochondritis dissecans (OCD) is a condition affecting joints, most commonly the knee, where a segment of bone underneath the cartilage dies due to insufficient blood supply. This process leads to the cartilage and underlying bone becoming loose or detached, potentially creating free-floating fragments within the joint. The condition is most frequently seen in children and adolescents, particularly those involved in sports. Treatment ranges from rest and activity modification to surgical intervention depending on the size and location of the lesion.
Usage
Usage note: Often abbreviated as OCD in clinical documentation; ensure context distinguishes from obsessive-compulsive disorder.
