“… Arno et al (2012) suggested that the meniscus is not able to reduce forces and pressures acting between the articular cartilage and prevent degeneration in medial knee OA. In our previous study ( Łuczkiewicz et al, 2016 ) we showed that the reduction in the role of the meniscus in the transmission of static load in the medial compartment may be attributed to incongruence between contact surfaces resulting from a 50% reduction in cartilage thickness. Here, the decrease in force between the tibial cartilage and the medial meniscus in model M ( Table 5 ) showed that the medial meniscus did not take a greater load in the OA model due to the reduction in its compressive stiffness.…”

“…The finite element method (FEM) serves as a useful tool for investigating the mechanical status of the knee joint in different pathological conditions ( Kluess et al, 2009 ; Łuczkiewicz et al, 2016 ). Previous works ( Peña et al, 2005 ; Zielinska & Haut Donahue, 2006 ; Mononen, Jurvelin & Korhonen, 2013 ; Shriram et al, 2019 ; Zhang et al, 2019 ; Li et al, 2020 ) have focused on the influence of degenerative meniscal tears and meniscectomies on knee biomechanics.…”

Background Increased mechanical loading and pathological response of joint tissue to the abnormal mechanical stress can cause degradation of cartilage characteristic of knee osteoarthritis (OA). Despite osteoarthritis is risk factor for the development of meniscal lesions the mechanism of degenerative meniscal lesions is still unclear. Therefore, the aim of the study is to investigate the influence of medial compartment knee OA on the stress state and deformation of the medial meniscus. Methods The finite element method was used to simulate the stance phase of the gait cycle. An intact knee model was prepared based on magnetic resonance scans of the left knee joint of a healthy volunteer. Degenerative changes in the medial knee OA model were simulated by nonuniform reduction in articular cartilage thickness in specific areas and by a decrease in the material parameters of cartilage and menisci. Two additional models were created to separately evaluate the effect of alterations in articular cartilage geometry and material parameters of the soft tissues on the results. A nonlinear dynamic analysis was performed for standardized knee loads applied to the tibia bone. Results The maximum von Mises stress of 26.8 MPa was observed in the posterior part of the medial meniscus body in the OA model. The maximal hoop stress for the first peak of total force was 83% greater in the posterior horn and only 11% greater in the anterior horn of the medial meniscus in the OA model than in the intact model. The reduction in cartilage thickness caused an increase of 57% in medial translation of the medial meniscus body. A decrease in the compressive modulus of menisci resulted in a 2.5-fold greater reduction in the meniscal body width compared to the intact model. Conclusions Higher hoop stress levels on the inner edge of the posterior part of the medial meniscus in the OA model than in the intact model are associated with a greater medial translation of the meniscus body and a greater reduction in its width. The considerable increase in hoop stresses shows that medial knee OA may contribute to the initiation of meniscal radial tears.

“…The material properties were assigned according to pertinent literature. Several studies 48–54,57 have assumed the femur and tibia as rigid bodies because of their relatively high density and Young’s modulus compared to the cartilage and menisci in the knee joint. On the other hand, previous FEA studies 56,58–62 did not take into account the difference between cancellous and cortical bone and considered the whole bony structure of the knee joint as cortical bone.…”

Osteoarthritis is a globally common disease that imposes a considerable ongoing health and economic burden on the socioeconomic system. As more and more biomechanical factors have been explored, malalignment of the lower limb has been found to influence the load distribution across the articular surface of the knee joint substantially. In this work, a three-dimensional finite element analysis was carried out to investigate the effect of varying the high tibial osteotomy correction angle on the stress distribution in both compartments of the human knee joint. Thereafter, determine the optimal correction angle to achieve a balanced loading between these two compartments. The developed finite element model was validated against experimental and numerical results. The findings of this work suggest that by changing the correction angle from 0° to 10° valgus, high tibial osteotomy shifted the mechanical load from the affected medial compartment to the lateral compartment with intact cartilage. The Von Mises and the shear stresses decreased in the medial compartment and increased in the lateral compartment. Moreover, a balanced stress distribution between the two compartments as well as the desired alignment were achieved under a valgus hypercorrection of 4.5° that significantly unloads the medial compartment, loads the lateral compartment and arrests the progression of osteoarthritis. After comparing the achieved results against the ones of previous studies that explored the effects of the high tibial osteotomy correction angle on either clinical outcomes or biomechanical outcomes, one can conclude that the findings of this study agree well with the related clinical data and recommendations found in the literature.
