Arthroscopic surgery to trimming damaged tissue from arthritic knees does not relieve pain and swelling any better than simply flushing loose debris from the joint.
Osteoarthritis is a progressive disease that affects the hands, hips, shoulders and knees, especially in older people. The condition causes joint cartilage to break down, and loose bits of tissue can then cause pain, swelling and poor joint function.
Arthroscopic surgery can cause infection and blood clots. The procedure does not stop the progression of osteoarthritis.
