Early postoperative clinical recovery of robotic arm-assisted vs. image-based navigated Total hip Arthroplasty

Abstract Background This study compared the early clinical recovery of total hip arthroplasty (THA) using computer navigation systems (nTHA) and robotic arm-assisted THA (rTHA). Methods Thirty prospective subjects who underwent rTHA were clinically to 30 nTHA. Clinical data (surgical time, intraoperative blood loss, pain severity, number days independent walking, Harris Hip Score (HHS) at discharge), radiographic parameters (inclination anteversion angles) statistically between two groups. Results Follow-up times 24.3 ± 6.0 27.0 7.0 in nTHA groups, respectively. The surgical time (135.1 13.9 min vs. 146.2 12.8 min, p = 0.002), walking (7.2 2.0 11.5 3.0 days, < 0.001), postoperative a numeric rating scale on 7, 10,, 14 (1.4 0.9 2.2 1.2, 0.005; 1.0 0.8 1.8 1.1, 0.002; 0.3 0.5 1.1 0.9, 0.001; respectively) significantly reduced group group. showed higher HHS (85.3 .3.2 81.0 8.5, 0.014). No significant difference was observed groups; however, incidence target angle changes lower than (0/30 [0%] 11/30 [36.7%], 0.001). Conclusion pain, shorter, discharge Thus, group, improved recovery.
