No Superiority of High-Flexion vs Standard Total Knee Arthroplasty: An Update Meta-Analysis of Randomized Controlled Trials
J Arthroplasty. 2015 Jun;30(6):980-617 randomized controlled trials analyzing patients who underwent total knee arthroplasty with a high-flexion versus standard prosthesis were included in this meta-analysis.

No significant differences were found in terms of range of motion, weight-bearing flexion, clinical outcomes and most complications. However, the high-flexion group was found to have a higher incidence of deep venous thrombosis.
