To evaluate the feasibility and clinical effectiveness of reconstructing the Medial Patellofemoral Ligament (MPFL) using robotic-assisted reconstruction.
This retrospective cohort study encompassed 46 patients who underwent medial patellofemoral ligament reconstruction at Yichang People's Hospital between January 2022 and January 2024. Patients were categorized into a conventional surgery group (control group, n = 24) and a robot-assisted surgery group (experimental group, n = 22) based on whether robotic assistance was used during the procedure. The primary endpoints included the error margin between the femoral tunnel entry point, a predefined reference landmark, and the quantity of intraoperative fluoroscopic exposures. Secondary endpoints consisted of knee function scores at postoperative and final follow-up evaluations, patellar stability, operative duration, length of hospital stay, and intraoperative blood loss.
The experimental group demonstrated a significantly higher degree of precision in femoral tunnel placement than the control group, as indicated by a smaller mean distance from the tunnel entry point to the reference landmark (P < 0.05). Additionally, the experimental group markedly reduced intraoperative fluoroscopic exposures relative to the control group (P < 0.05). No significant differences were observed between the two groups regarding postoperative or final follow-up patellar stability or knee function scores (P > 0.05). Furthermore, the experimental group incurred significantly shorter hospital stays and experienced less intraoperative blood loss than the control group (P < 0.05). At the same time, the operative time did not present any significant differences between groups (P > 0.05).
Robot-assisted MPFL reconstruction significantly enhances femoral tunnel positioning accuracy and surgical efficiency compared to conventional methods. This approach offers a promising surgical option for improving precision and efficiency in the management of recurrent patellar dislocation, with potential implications for future research.
评估使用机器人辅助重建内侧髌股韧带（MPFL）的可行性和临床效果。
这项回顾性队列研究纳入了2022年1月至2024年1月在宜昌市人民医院接受内侧髌股韧带重建的46例患者。根据手术过程中是否使用机器人辅助，将患者分为传统手术组（对照组，n = 24）和机器人辅助手术组（实验组，n = 22）。主要终点包括股骨隧道入口点与预定义参考标志之间的误差范围以及术中透视曝光次数。次要终点包括术后和最终随访评估时的膝关节功能评分、髌骨稳定性、手术持续时间、住院时间和术中失血量。
实验组在股骨隧道放置方面的精度明显高于对照组，从隧道入口点到参考标志的平均距离更小（P < 0.05）。此外，实验组相对于对照组显著减少了术中透视曝光次数（P < 0.05）。两组在术后或最终随访时的髌骨稳定性或膝关节功能评分方面未观察到显著差异（P > 0.05）。此外，实验组的住院时间明显短于对照组，术中失血量也更少（P < 0.05）。同时，两组之间的手术时间没有显著差异（P > 0.05）。
与传统方法相比，机器人辅助MPFL重建显著提高了股骨隧道定位的准确性和手术效率。这种方法为提高复发性髌骨脱位治疗的精度和效率提供了一种有前景的手术选择，对未来研究具有潜在意义。
