Influence of Meniscal attachments placement on articular stress deterioration
Meniscal attachments provide constraint for meniscus and contribute to knee stability.However,the influence of attachments placement on articular mechanical environment remains unclear.The present study aims to characterize the stress deterioration caused by abnormal attachment locations.Different placement of medial meniscal attachments were analyzed with a three-dimensional (3D) finite element (FE) model of knee joint.The articular stress distribution under compressive loadings indicates that abnormal placement of medial meniscal attachments could cause stress deterioration in meniscus and tibia plateau,which may increase the risk of OA.The influence of PMMA relocation was more severe than that of AMMA.The anterior displacement of both AMMA and PMMA could decrease the tibial contact area and therefore weaken the meniscal function of loading transmission.The present study provides an insight into the biomechanical character of meniscal attachments and may help improving the meniscal transplantation in the future.
