“…Thus, the mean absolute measurement accuracy value obtained in the present study (4.9°) seems to be acceptable. Several studies have reported that knee OA and the femorotibial angle significantly influenced measurement accuracy during THA [13,16]. In the current study, knee OA was shown to significantly influence measurement accuracy during THA, which is consistent with the other studies.…”

“…Fourth, we checked the vertical position of the tibia in visual assessment during the intraoperative measurement of stem anteversion. Although this was similar to other clinical studies [13,16,18,25], it can affect the accuracy of measurements. Finally, we did not evaluate postoperative clinical outcomes; however, this was beyond the purpose of this study.…”

“…Several studies have investigated the accuracy of measurements obtained using a goniometer or navigation systems during THA [12][13][14][15][16] (Table 4). They reported that the mean absolute measurement accuracy ranged from 4.5°-7.3°.…”

“…Many studies have reported the optimal positions for the acetabular components, and the accuracy of acetabular component positioning using free-hand techniques, mechanically guided techniques, or navigation systems have also been investigated [8][9][10][11]. Other studies have examined the accuracy of intraoperative measurements of stem anteversion obtained using a goniometer or navigation systems during THA [12][13][14][15][16]. However, only one CTbased navigation study has reported the accuracy of stem positioning during THA [17].…”

Background: During total hip arthroplasty (THA), the accurate placement of the femoral components is an important determinant of the success of the procedure. This study assessed the accuracy of cemented stem placement using a new angle-measuring instrument. The primary objective was to investigate the accuracy of the intraoperative measurements of cemented stem anteversion obtained using the angle-measuring instrument. Our secondary objective was to evaluate the accuracy of stem positioning performed using the angle-measuring instrument. Methods: We compared the intraoperative stem anteversion measurements obtained using the angle-measuring instrument with postoperative stem anteversion measurements obtained using computed tomography in 149 hips (measurement accuracy). We also compared the target angle and postoperative stem anteversion in 105 hips (implantation accuracy). Results: The mean amount of intraoperative stem anteversion was 37.9°± 10.1°, and the mean amount of postoperative stem anteversion was 37.0°± 10.4°. The mean measurement accuracy was 0.9°± 6.1°, and the absolute measurement accuracy was 4.9°± 3.7°. The correlation coefficient for the relationship between the intraoperative and postoperative stem anteversion measurements was 0.824 (p = 0.000). The mean amount of target angle was 37.4°± 7.6°, and the mean amount of postoperative stem anteversion was 35.9°± 9.1°. The mean implantation accuracy was 1.4°± 5.6°, and the mean absolute implantation accuracy was 4.3°± 3.6°. The correlation coefficient for the relationship between the target angle and postoperative stem anteversion was 0.795 (p = 0.000). Conclusions: The angle-measuring instrument measured intraoperative stem anteversion accurately, and cemented stem was implanted accurately during THA with the angle-measuring instrument.

“…Two of these cases had advanced osteoarthritis of the knee joint. Hirata et al [17] reported that in such cases the estimated prosthetic anteversion is generally larger than the true anteversion, and the grade of knee osteoarthritis influences the degree of surgeon error.…”

The objectives were to determine errors in femoral anteversion (FA), femoral offset (FO), and vertical offset (VO) with robot‐assisted total hip arthroplasty (THA) and how consistently these errors are within clinically desirable limits of ±5° and ±5 mm. After preoperative planning, robot‐assisted THAs were performed on twelve cadaveric specimens. The error between achieved and planned component placements was used to determine bias (mean error) and precision (SD of error). The percent of the population within clinically desirable limits was determined. Bias of 1.5° and 2.7 mm occurred for FA and VO, respectively. Precision was 1.2° for FA and better than 1.5 mm for FO and VO. The percent of population within clinically desirable limits was at least 95% for FA and at least 99% for FO. With limits of ±7 mm, at least 95% of the population was within these limits for VO. Robot‐assisted THA may improve clinical outcomes.
