Proponents of minimally invasive TKA claim that lateral retraction, rather than eversion, of the patella may be beneficial. Many randomized controlled studies attempt to identify this issue; however, no final conclusion arrives. With this systemic review and meta-analysis, we intended to test whether patella eversion during TKA had deleterious effects. Methods: A comprehensive literature search was performed in PubMed, MEDLINE, EMBASE and other internet database. We retrieved all the relevant studies designed to interpret this issue. The searching time frame was from the establishing of these databases until July 2014. Results: Six randomized controlled trials assessing a total of 414 patients and 451 knees were included. The duration of surgery was much shorter (p=0.003), and the length of skin incision was much longer (p<0.00001). No significant difference was found on other measurements, including length of hospital stay, quadriceps strength, complications, straight leg raise, Visual Analogue Scale score and functional scores. Conclusions: Patella eversion could decrease the duration of the surgery; nevertheless, the length of skin incision was longer; no significant difference was found on other measurements, especially the quadriceps strength and complications which were concerned. Patella eversion and patella lateral retraction could achieve similar clinical outcomes. Level of evidence: Systematic review and meta-analysis, Level I.
