Arthroscopic treatment of osteoarthrifis of the knee - Are there any evidence-based indications?

Despite the lack of consensus guidelines and randomized control trials, the use of arthroscopy for the treatment of osteoarthritis of the knee has increased over the last decade. Techniques used for the arthroscopic treatment of osteoarthritis of the knee include joint lavage, joint debridement, meniscectomy, abrasion arthroplasty, and microfracture. We performed a retrospective, evidence-based review of the current literature on the arthroscopic treatment of osteoarthritis of the knee and provide insight into the study design flaws and difficulties associated with the current research on this controversial topic. Our literature search yielded 18 relevant studies. Of these, one was Level I evidence, five were Level II, six were Level III, and six were Level IV. We found limited evidence-based research to support the use of arthroscopy as a treatment method for osteoarthritis of the knee. Arthroscopic debridement of meniscus tears and knees with low-grade osteoarthritis may have some utility, but it should not be used as a routine treatment for all patients with knee osteoarthritis. Level of Evidence: Level IV, systematic review. See Guidelines for Authors for a complete description of levels of evidence.
