- W4313452100 abstract "Abstract Backgrounds: Although most scholars believe that suture is the best way to treat horizontal cleavage tears (HCT), they often choose partial meniscectomy resection because it is very difficult to suture horizontal meniscal tears by arthroscope and it is difficult to heal. However, there seems to be no conclusion as to which of the popular single lobectomy and double lobectomy has the least effect on the internal pressure of the knee. So we hope to use a three-dimensional model of the knee joint to simulate this process, so as to draw conclusions. This study aims to establish a finite element model of meniscus horizontal fracture and partial resection, and to simulate the mechanical changes of knee joint under 0°, 10°, 20°, 30°, 40° flexion angles, and to explore what is the optimal surgical plan. Methods The MRI data of the knee joint were extracted, and the 3D model was reconstructed by Mimics Research, Geomagic Wrap and SolidWorks software. The mechanical simulation was carried out in AnsysWorkbench to compare the mechanical changes of knee joint under different meniscectomy models. Results The analysis results showed that the changes of pressure, shear force and stress area in the medial and lateral compartments of the knee model with the resection of the upper lobe of the meniscus horizontal cleft were the most similar to the changes of the knee model with the meniscus horizontal cleft. Conclusion Suture repair is the best way to maintain the force relationship in the knee joint. However, resection of the upper lobe of the meniscus is also a reliable choice when suture repair is difficult." @default.
