摘要

目的本研究利用自主开发的BioMxsf软件，通过膝关节三维成像模型，建立一个辅助前交叉韧带（ACL）重建手术过程的虚拟手术系统。介绍这些技术方法可以为临床改进ACL重建提供参考。方法对患者膝关节数据进行扫描，导入BioMxsf软件，建立膝关节三维图像模型。建立虚拟手术系统，支持ACL重建手术的操作过程。在虚拟手术系统的辅助下对患者进行ACL重建手术。结果BioMxsf模拟组（BSG）平均手术时间为97.7±8.5 min。常规手术组（CSG）手术时间为107.4±7.8 min，手术时间明显缩短（P≤0.014，卡方检验）。功能评分方面，CSG评分为81.4±3.14分。BSG评分为84.97±3.97，BSG组患者术后膝关节功能优于CSG组，差异有统计学意义（P = 0.016）。虽然功能评分达到了统计学意义，但它们低于报道的最小临床重要差异，不太可能具有临床意义。结论本研究证明虚拟手术系统辅助ACL重建的临床可行性。虚拟手术系统大大缩短了手术时间，提高了ACL重建的安全性。

Clinical comparative evaluation of anterior cruciate ligament reconstruction supported by an orthopedic surgical simulation system

Objective

This study utilizes self-developed BioMxsf software to establish a virtual surgical system that assists in the surgical process of anterior cruciate ligament (ACL) reconstruction through a three-dimensional imaging model of the knee joint. Introducing these technical methods can provide insights and references to improve ACL reconstruction in clinical practice.

Methods

After scanning the knee joint data of patients and importing it into the BioMxsf software, a three-dimensional image model of the knee joint was created. A virtual surgical system was established to support the operational process of ACL reconstruction surgery. The ACL reconstruction surgery was performed on patients with the assistance of the virtual surgical system.

Results

The average surgical time for the BioMxsf simulation group (BSG) was 97.7 ± 8.5 min. In contrast, the surgical time for the conventional surgery group (CSG) was 107.4 ± 7.8 min, indicating a significant reduction in surgery duration (P ≤ 0.014, Chi-square test). In terms of functional scores, the CSG had a score of 81.4 ± 3.14. In contrast, the BSG scored 84.97 ± 3.97, demonstrating that patients in the BSG had better postoperative knee function than those in the CSG, with a statistically significant difference (P = 0.016). Although the functional scores reached statistical significance, they were below the reported minimal clinically important difference and are unlikely to be clinically meaningful.

Conclusion

This study demonstrated the clinical feasibility of a virtual surgical system to assist ACL reconstruction. The virtual surgical system significantly reduced operative time and enhanced ACL reconstruction’s safety.
