Superior Mid- to Long-Term Clinical Outcomes of Mobile-Bearing Total Knee Arthroplasty Compared to Fixed-Bearing: A Meta-Analysis Based on a Minimum of 5 Years of Study
J Knee Surg. 2021 Oct;34(12): 1368-1378.17 randomized controlled trials including 3283 patients undergoing total knee arthroplasty were identified in this meta-analysis comparing fixed-bearing and mobile-bearing implants.
