Arthroscopic surgery is not superior to conservative treatment in knee osteoarthritis: a systematic review and meta-analysis of randomized controlled trails.
Systematic Review
Studies comparing the effectiveness of arthroscopic knee surgery and conservative treatment on knee osteoarthritis (OA) came up with inconsistent results. Systematic review on this topic still is still lacking. This systematic review and meta-analysis aimed to evaluate the effectiveness of arthroscopic knee surgery on knee OA, compared to conservative treatments./r/nLiterature searches were performed in PubMed, Embase, and Cochrane Library databases for randomized controlled trials (RCTs) published before on 1st July 2024. Studies comparing the effectiveness of arthroscopy and conservative treatments only on knee OA were included. Quality of included studies was evaluated by risk of bias 2 (ROB2). Long-term results in terms of pain relief, functional recovery and patients reported satisfaction were meta-analyzed to evaluate the therapeutic effectiveness./r/nTen studies were included in this review, among which only 1 was considered as low risk of bias. Five studies were involved in meta-analyses and no difference was found in therapeutic effectiveness of arthroscopic surgery and conservative treatment on knee OA, in the evaluation of VAS (p = 0.63), WOMAC (p = 0.38), SF-36 (p = 0.74) and patient satisfaction (p = 0.07)./r/nThe evidence does not support the effectiveness of arthroscopic knee surgery compared to conservative treatments in knee OA.
