Objective This study aimed to investigate the correlation between the surface area ratio of medial tibial plateau(MTP)to lateral tibial plateau(LTP)and the mechanical tibiofemoral angle(mTFA).Methods Lower limb computed tomography(CT)images were collected at our ***,the original CT data were analyzed and reconstructed using medical image processing *** proximal and distal centres of the femur and tibia were *** surface areas of MTP and LTP were identified using image processing *** Prism 8.0.2 was used to perform the statistical *** The surface area ratio of MTP to LTP was significantly correlated with the mTFA in all patients(Pknee arthroplasty,of whom the surface area of the MTP was basically equal to that of the LTP,it is recommended that the osteotomy should be performed in accordance with mechanical alignment standards,and that a symmetrical tibial plateau prosthesis should be *** patients whose surface area of MTP is significantly greater than that of the LTP,it is recommended that the osteotomy should be performed in accordance with kinematic alignment standards,and that an anatomical tibial plateau prosthesis should be used.
