This study investigates an alternative surgical approach for repairing meniscal root tears, a common knee injury that can significantly impact joint stability and function. Traditional repair methods often face challenges such as high rates of retear and persistent pain. To address these limitations, this research utilizes finite element analysis (FEA) to compare the biomechanical performance of an alternative technique against established surgical procedures. FEA models were carefully constructed to accurately represent the complex anatomy of the knee joint, including the medial meniscus, cartilage, ligaments, and surrounding bone structures. These models were then subjected to various loading conditions that simulated physiological activities such as walking, running, and squatting to assess the stress and strain experienced by the repaired tissue under realistic conditions. The results of the FEA simulations demonstrated a significant reduction in stress and strain on the repaired medial meniscus root when the alternative technique was employed compared to traditional methods. This reduction in biomechanical load is crucial for promoting tissue healing and minimizing the risk of retear. By reducing excessive stress on the repair site, the alternative surgical technique may enhance long-term patient outcomes, potentially improving knee function, reducing pain, and decreasing the likelihood of further surgical interventions such as meniscectomy or knee prosthesis replacement. In conclusion, this study provides strong evidence for the potential benefits of the alternative surgical technique in repairing meniscal root tears. The findings suggest that this approach may offer a promising alternative to traditional methods by optimizing biomechanical stability and promoting more favorable healing conditions. Further clinical studies are warranted to validate these findings and translate these promising results into improved patient care.
本研究探讨了一种用于修复半月板根部撕裂的替代性手术方法，半月板根部撕裂是一种常见的膝关节损伤，会对关节稳定性和功能产生重大影响。传统的修复方法常常面临诸如再撕裂率高和持续疼痛等挑战。为解决这些局限性，本研究利用有限元分析（FEA）来比较一种替代技术与既定手术程序的生物力学性能。精心构建了有限元分析模型，以准确呈现膝关节的复杂解剖结构，包括内侧半月板、软骨、韧带和周围的骨骼结构。然后让这些模型承受各种模拟生理活动（如行走、跑步和下蹲）的加载条件，以评估修复组织在实际情况下所经历的应力和应变。有限元分析模拟结果表明，与传统方法相比，采用替代技术时，修复后的内侧半月板根部的应力和应变显著降低。这种生物力学负荷的降低对于促进组织愈合和将再撕裂风险降至最低至关重要。通过减少修复部位的过度应力，这种替代性手术技术可能会改善患者的长期预后，有可能改善膝关节功能、减轻疼痛，并降低诸如半月板切除术或膝关节假体置换等进一步手术干预的可能性。总之，本研究为替代性手术技术在修复半月板根部撕裂方面的潜在益处提供了有力证据。研究结果表明，这种方法可能通过优化生物力学稳定性和促进更有利的愈合条件，为传统方法提供一种有前景的替代方案。有必要进行进一步的临床研究来验证这些发现，并将这些有前景的结果转化为改善患者护理。
