Trimming damaged tissue through arthroscopic knee surgery does not relive pain and swelling in arthritic knees any better than simply flushing loose debris from the joint, according to new research.
The findings are based on three randomized studies, one of which found the treatments produced similar results in pain and physical function after two years. The other two studies produced low-quality evidence, according to researchers.
Potential side effects of arthroscopic surgery include a risk of infection and blood clots. Further, the surgery does not stop the progression of osteoarthritis, and symptoms are likely to return over time.
Osteoarthritis is a progressive disease that affects your 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.
