Patellar fractures present challenges in treatment, with traditional methods often leading to complications such as loss of reduction and implant failure. This study aimed to compare a novel suture fixation technique with the traditional tension band method using finite element analysis.
CT images of a healthy 35-year-old male were used to construct 3D patellar models. Two fixation methods were modeled: the novel suture technique using polyester sutures and traditional tension band fixation with Kirschner wires and cerclage wires. Finite element analysis was conducted to compare stress and pressure distribution under varying force angles.
The novel suture fixation method demonstrated superior stress dispersion and more uniform pressure distribution compared to the traditional tension band technique. Stress concentration was notably reduced, indicating potential for enhanced fracture stability and healing. Tensile testing confirmed the mechanical properties of the sutures, further validating the proposed method.
Finite element analysis revealed that the novel suture technique for patellar fractures provides better stress and pressure distribution compared to traditional methods. This approach offers promise for improved fracture stability and reduced complications. Clinical validation and long-term follow-up studies are warranted to confirm these findings and assess patient-specific outcomes.
髌骨骨折的治疗具有挑战性，传统方法常常导致诸如复位丢失和植入物失败等并发症。本研究旨在使用有限元分析比较一种新型缝合固定技术与传统张力带方法。
使用一名35岁健康男性的CT图像构建三维髌骨模型。模拟了两种固定方法：使用聚酯缝线的新型缝合技术和使用克氏针及环扎钢丝的传统张力带固定。进行有限元分析以比较不同力角度下的应力和压力分布。
与传统张力带技术相比，新型缝合固定方法显示出更好的应力分散和更均匀的压力分布。应力集中显著降低，表明骨折稳定性和愈合得到增强的潜力。拉伸试验证实了缝线的力学性能，进一步验证了所提出的方法。
有限元分析表明，与传统方法相比，用于髌骨骨折的新型缝合技术提供了更好的应力和压力分布。这种方法有望提高骨折稳定性并减少并发症。需要进行临床验证和长期随访研究以证实这些发现并评估患者特定的结果。
