【Abstract】Objective: MAKO robot-assisted total hip arthroplasty (THA) patients were followed up for one year to analyze the clinical results and complications.Methods: data from March 2017 to March 2018 were collected and retrospectively analyzed. The inclusion criteria were robot-assisted posterior lateral approach. THA was used to treat patients with hip osteoarthritis caused by various reasons, except rheumatoid hip arthritis and DDH patients with grade 4 or above. Follow-up 1 year. Statistical data, operation time, complications, 1 year postoperative outcome score and satisfaction.Results :22cases met the inclusion criteria, of which 17cases (78.5%) were followed up for 1 year. Follow-up results showed that the average visual simulation score (VAS) was 0.7, satisfaction was 95%,Harris hip score was 91.1, and forgetting joint score (fjs-12) was 89.1%. Intraoperative complications in 1 case (4.5%) were reported. No leg length differences (LLD) or dislocation were reported. Conclusion: MAKO robot-assisted posterolateral approach THA has a good short-term efficacy, with more accurate prosthesis implantation, which is more conducive to maintaining the biomechanical environment of hip joint and reducing the incidence of intraoperative and postoperative complications.
