Comparison of Surgical Time, Short-term Adverse Events, and Implant Placement Accuracy Between Manual, Robotic-assisted, and Computer-navigated Total Hip Arthroplasty: A Network Meta-analysis of Randomized Controlled Trials.

Interestingly, a recent meta-analysis of seven robotic-assisted versus manual THA studies reported that the odds ratio for postoperative complications for robotic-assisted THA compared with manual THA was 3.35 (95% confidence internal, 0.94 to 11.91), although this did not reach statistical significance ( P = 0.06). 35 However, these authors also reported that (1) the rate of dislocations was higher in the robotic cohort than the manual cohort, (2) the rate of revision was slightly higher in robotic patients (two versus one) and was attributed to abductor insufficiency, and (3) one included study noted a significantly higher rate of Trendelenburg signs postoperatively in robotic patients (61% versus 26%, P = 0.0014).
