Arthroscopy is used to find and treat many types of ankle problems. These include loose bodies, bone spurs, osteochondritis dissecans (OCD), and synovitis.
A loose body is removed.
Loose bodies are bone or cartilage fragments that have chipped off inside the joint. If left in place, they can damage the joint surface and restrict ankle movement. Your surgeon can remove loose bodies from the joint. This will help restore normal, smooth ankle motion.
A bone spur is removed, and the surface of the bone is smoothed.
When the bones in a joint pinch each other, they are impinged. This problem is often caused by bone spurs (growths) that have formed on the joint. Pressure from the spur may cause pain when you move your ankle. Your surgeon will remove the spur and smooth the bone surface.
OCD is treated by securing the affected piece of bone in place.
Because of an injury to its blood supply, a piece of bone can become loose inside the joint. Called OCD (osteochondritis dissecans), this problem can cause pain and swelling. The surgeon can remove the bone or secure it in place. Open surgery may also be needed.
If the lining of the joint (synovium) is pinched, it may become inflamed. This can cause pain and swelling in the ankle. The surgeon can remove the pinched synovium and relieve symptoms.
