Five studies reported intraoperative blood loss. We found statistical heterogeneity between the two groups (x2 = 26.76, df = 4, P = 0.000; I2 = 85.1%). TiRobot would decrease intraoperative blood loss [MD = − 1.10, 95% CI (− 1.85, − 0.34), P = 0.005]. Eight studies reported operative time. We found statistical heterogeneity between the two groups (x2 = 184.87, df = 7, P = 0.000; I2 = 96.2%). Both groups experienced a similar operative time (MD = − 1.24, 95% CI (− 2.51, − 0.02), P = 0.055]
