Summary: For patients with knee pain who are middle aged or older, whether or not they have knee osteoarthritis, there may be no long-term difference in physical function outcomes between arthroscopic and non-operative management, while arthroscopic surgery may be associated with increased risk of deep-vein thrombosis, infection, pulmonary embolism, or death. (In other words, patients with knee pain who are treated non-operatively may function just as well over time as those who have arthroscopic surgery, without the risks that may accompany arthroscopic surgery.)
