Arthroscopic Surgery for Knee Pain

Overview
Arthroscopy surgery involves inserting small instruments through small cuts in the knee. The majority of patients with knee pain will not require arthroscopy, and recent reviews suggest it may not be effective for osteoarthritis. It may however be required when conservative care is unsuccessful at resolving the problem and other measures have proven ineffective, such as for meniscal tears or ligament injuries.

RISK: 4/5
Knee arthroscopy still has the risks of most surgeries, including anesthesia risks and the potential for blood clots and infection, though one recent study showed those occurred in just over 1% of patients. The risk of all complications was as high as 8%.
