[A comparative study of MAKO robotic arm assisted total hip arthroplasty and traditional total hip arthroplasty through posterolateral approach].

摘要

OBJECTIVE: To investigate the efficacy of total hip arthroplasty (THA) assisted by the MAKO robotic arm via posterolateral approach. METHODS: >0.05). The operation time, intraoperative blood loss, hospital stay, postoperative acetabular abduction and anteversion angles, postoperative length difference of bilateral lower limbs, and proportions of intraoperative blood transfusion, immediate postoperative loading, wound drainage time more than 2 days, and complications were recorded and compared between the two groups. According to the X-ray films at 6 months after operation, the reduction quality was judged. The forgotten joint score, Harris score, and proportions of independent walking and ADL index increased were used to evaluate the function recovery of patients. RESULTS: >0.05). CONCLUSION: Compared with traditional THA, MAKO robotic arm assisted THA has longer operation time and more intraoperative blood loss, but it has the advantages of accurate positioning and simple operation, and there is no significant difference in short-term postoperative function recovery.
