Loose Body Knee
Loose bodies are small loose fragments of cartilage or a bone that float around the joint. Loose bodies in the knee joint can cause pain, swelling, locking and catching of the joint. It can occur due to bleeding within the joint, death of tissues lining the joints associated with tuberculosis, osteoarthritis, and rheumatoid arthritis. Other causes include fractures, trauma, bone and cartilage inflammation, and benign tumors of the synovial membrane. Surgery is performed depending on the location and the size of the loose bodies. An arthroscopic procedure is usually performed.
