Abstract The primary objective of our meta-analysis was to compare the incidence of complications between minimally invasive surgery and standard total knee arthroplasty (TKA) approaches. We reviewed randomized controlled trials comparing minimally invasive TKA to standard TKA. After testing for publication bias and heterogeneity, the data were aggregated by random effects modeling. Our primary outcome was the number of complications. Our secondary outcomes were alignment outliers, Knee Society Function scores, and Knee Society Knee scores. The combined odds ratios for complications for the minimally invasive surgery group and alignment outliers were 1.58 (95\% confidence interval, 1.01-2.47; P < .05) and 0.79 (95\% confidence interval, 0.34-1.82; P = .58), respectively. The standard difference in means for Knee Society scores was no different between groups. Minimally invasive knee surgery should be approached with caution. Copyright © 2011 Elsevier Inc.
