Abstract:
We investigated the accuracy of implant positioning during total hip arthroplasty (THA) through a minimally invasive approach in relation to body mass index (BMI) and gender by assessing 48 patients. Functional and radiological parameters were evaluated. BMI positively correlated with operation time (p=0.04), but BMI and gender had no influence on implant positioning. The Harris hip score (HHS) increased significantly (46.5 ± 11.8 preoperatively, 92.1 ± 9.7 postoperatively, p<0.0001). The surgical approach described resulted in reproducibility of implant positioning independent of influence by BMI or gender.
