Eight studies reported an overall excellent and good rate of screw accuracy. We found some statistical heterogeneity between the two groups (x² = 12.49, df = 7, P = 0.086; I² = 43.9%). TiRobot would improve screw accuracy [RR = 1.09, 95% CI (1.02, 1.16), P = 0.011]. Five studies reported an overall excellent and good rate of reduction. We found some statistical heterogeneity between the two groups (x² = 7.97, df = 4, P = 0.093; I² = 49.8%). Both groups experienced a similar excellent and good rate of reduction accuracy [RR = 1.04, 95% CI (0.95, 1.13), P = 0.426]
