Abstract
Purpose: To assess the efficacy and safety for bone tunnel drilling in anatomic anterior cruciate ligament (ACL) reconstruction with the assistance of a surgical navigation robot system.
Methods: A total of 79 patients were randomized to either surgical navigation robot group (robot group, n = 39) or traditional handheld locator group (control group, n = 40). The robot group underwent anatomic ACL reconstruction using a surgical navigation robot, while the control group underwent the procedure using a traditional handheld locator. Postoperative three-dimensional computed tomography was used to measure the tibial and femoral tunnel position, as well as the tibial and femoral tunnel length. The success rate of femoral tunnel positioning was defined as the proportion of cases in which the femoral tunnel was placed accurately within the ideal anatomical position.
Results: The success rate of femoral tunnel positioning in the robot group was significantly higher than that in the control group (82.1% vs 50%, P = 0.003). The surgical time in the robot group was significantly longer than that in the control group (122.8 min ± 34.9 min vs 84.0 min ± 28.3 min, P = 0.05). The incidence rate of adverse events did not show statistical significance between the two groups (P = 0.830). There were no adverse events associated with the instruments or any serious adverse events, and no patients withdrew from the trial due to adverse events.
Conclusions: The success rate for femoral tunnel positioning in anatomic ACL reconstruction was higher with surgical navigation robots compared to the traditional handheld locator. Surgical navigation robot systems are safe tools in anatomic ACL reconstruction surgery.
目的：评价导航机器人辅助下骨隧道钻孔在解剖前交叉韧带（ACL）重建中的有效性和安全性。方法：79例患者随机分为手术导航机器人组（机器人组，n = 39）和传统手持式定位器组（对照组，n = 40）。机器人组使用外科导航机器人进行解剖ACL重建，而对照组使用传统的手持式定位器进行手术。术后三维计算机断层扫描测量胫骨和股骨隧道位置，以及胫骨和股骨隧道长度。股骨隧道定位成功率定义为股骨隧道准确放置在理想解剖位置的病例比例。结果：机器人组股骨隧道定位成功率明显高于对照组（82.1% vs 50%, P = 0.003）。机器人组手术时间明显长于对照组（122.8 min±34.9 min vs 84.0 min±28.3 min, P = 0.05）。两组不良事件发生率比较，差异无统计学意义（P = 0.830）。没有与器械相关的不良事件或任何严重不良事件，也没有患者因不良事件退出试验。结论：与传统的手持式定位器相比，手术导航机器人在解剖性ACL重建中股骨隧道定位的成功率更高。手术导航机器人系统是解剖ACL重建手术的安全工具。
期刊介绍：
The International Journal of Surgery (IJS) has a broad scope, encompassing all surgical specialties. Its primary objective is to facilitate the exchange of crucial ideas and lines of thought between and across these specialties.By doing so, the journal aims to counter the growing trend of increasing sub-specialization, which can result in "tunnel-vision" and the isolation of significant surgical advancements within specific specialties.
