Removal of loose bodies is a common reason physicians perform arthroscopic hip surgery. These loose bodies are often the result of trauma, such as a fall, an automobile accident, or a sports-related injury, or they may result from degenerative disease. When a torn labrum rubs continuously against cartilage in the joint, this may also cause fragments to break free and enter the joint. Loose bodies can cause a “catching” in the joint.
Unlike some hip conditions, loose bodies are relatively easy to detect with modern x-ray techniques. Once diagnosed, the removal of loose bodies through hip arthroscopy usually results in a significant reduction in hip pain.
