Utility of Arthroscopic Surgery for Osteoarthritis of the Knee.

Currently, there is no consensus as to which patients would benefit most from arthroscopic surgery of the knee. Recently published randomized trials have shown limited efficacy for arthroscopic debridement and partial meniscectomy in patients with knee osteoarthritis. However, these clinical trials and others are limited by methodological problems. Indeed, many surgeons believe that arthroscopic surgery is indicated in a select group of patients, namely those with mild osteoarthritis and associated meniscal injury. More level I evidence will be required to better define the role of arthroscopic surgery in patients with osteoarthritis of the knee.
