Abstract:PurposeTotal knee arthroplasty (TKA), which has medial pivot and mobile‐bearing mechanisms, has been developed and clinically used. However, the in vivo dynamic kinematics of the mobile medial pivot‐type TKA (MMPTKA) is unclear. This study analysed the in vivo kinematics of MMPTKA in weight‐bearing and nonweight‐bearing conditions.MethodsThe study included 10 knees that underwent primary TKA using MMPTKA. After TKA, lateral view radiographs of the knee in full extension, 90° of flexion and passive full flexion… Show more
