Abstract

BACKGROUND: Loose Bodies are fragments consisting of cartilage or bone that move freely in the joint space. The occurrence of Loose Bodies associated with OCD is considered a rare case in Indonesia. The presence of Loose Bodies can cause several symptoms such as pain and resistance to extension and flexion of the knee joint. The presence of an impinging osteophyte in the lateral condyle of the femur, and a pedunculated osteophyte, can provide a clinical feature similar to Loose Bodies. Good anamnesis, physical examination, and diagnosis for correct management can provide a good outcome.
