Abstract

Purpose

Multiple surgical techniques in minimally invasive total knee arthroplasty (TKA) are associated with clinical differences. However, whether patellar eversion impairs clinical outcomes remains controversial. We conducted a systematic review of randomized controlled trials (RCTs) to provide current understanding on this topic.

Methods

A literature search of the PubMed, Embase, and Cochrane library databases was performed to identify RCTs comparing patellar eversion with patellar non-eversion (PN). Two authors independently selected the studies, assessed methodological quality, and extracted data.

Results

Five RCTs involving 379 knees were included. The results revealed no significant differences in functional scores, pain, quality of life, quadriceps strength, patellar height, alignment, or complication rate between patellar eversion and PN. Power analysis showed that the power of the individual study and meta-analysis ranged from 5.0 to 70.8 %, with the exception of the power of alignment and patellar height in two of the individual studies, which was 100.0 and 99.9 %, respectively.

Conclusions

Based on the current evidence, patellar eversion during TKA could not definitely lead to inferior postoperative outcomes. Patellar eversion and patellar non-eversion could achieve similar clinical outcomes.
