About
This is a randomized controlled, multicenter study. According to the inclusion criteria, volunteers were recruited from patients undergoing total hip arthroplasty. After signing the informed consent, the subjects were assigned to the experimental group and the control group through the central randomization system. The researchers will complete the total hip arthroplasty for patients in the experimental group with the assistance of surgical navigation system. The patients in the control group do not use the surgical navigation system. The proportion of acetabular abduction angle and anteversion angle in the lewinnek safe area is the primary outcome measurement. The operation time, WOMAC score, Harris score, range of motion and dislocation rate are the secondaryoutcome measurements. The incidence of complications, devices and other adverse events were recorded.
