Application and Exploration of Total Hip Arthroplasty for Developmental Dysplasia of the Hip Assisted by Full-Process Robotics

Abstract

Purpose To explore the clinical efficacy of total hip arthroplasty (THA) assisted by full-process robotics in patients with developmental dysplasia of the hip (DDH). Methods Sixty-four patients were divided into two groups: the robotic-assisted group (n = 32) and the conventional group (n = 32). A retrospective study was conducted to compare the therapeutic differences between the two groups. Results All 64 patients underwent THA successfully, with an average follow-up time of (12.27 ± 0.17) months, and no relevant complications occurred. In the robotic-assisted group, the anteversion angle and abduction angle of the acetabular cup placement were within the safe zone, while in the conventional group, there were 4 cases outside the safe zone. The postoperative Harris score and FJS score were higher, and the VAS score was lower in the robotic-assisted group compared to the conventional group. Conclusion Robotic-assisted THA demonstrates advantages in intraoperative precision and postoperative efficacy in treating patients with developmental dysplasia of the hip compared to the conventional manual approach.
