Computer-Assisted Total Hip Arthroplasty Improves Acetabular Prosthesis Placement Accuracy: A Multicenter, Randomized Controlled Clinical Study.
Orthop Surg . 2024 Dec;16(12):3078-3087.One hundred and thirteen patients undergoing primary total hip arthroplasty were randomized to receive either VTS-assisted THA (n=58) or conventional THA (n=55). The primary outcome was the proportion of acetabular anteversion and inclination angles falling within the Lewinnek safe zone. Secondary outcomes included operation time, WOMAC score, Harris score, SF-36 score, and hip dislocation rate, assessed at 3 months postoperatively. Overall, the results of the study revealed that VTS-assisted THA significantly improved prosthesis placement accuracy but did not affect short-term clinical outcomes or dislocation rates. The findings suggest VTS navigation enhances surgical precision without compromising safety.
