Similar clinical efficacy between patellar eversion and lateral retraction during TKA .
No difference in clinical outcome between patella eversion and lateral retraction in total knee arthroplasty: a systemic review and meta‑analysis
Knee Surg Sports Traumatol Arthrosc. 2015 Jun;23(6):1791-86 randomized controlled trials (RCTs) with a total of 414 patients and 452 knees were included in this meta-analysis to determine the effect of patella eversion versus lateral retraction during total knee arthroplasty (TKA).
