Brief summary
This is a multicenter, prospective, and case-control study. Five joint centers and 100 participants will be included. The study group used robotic-assisted modified kinematic alignment total knee replacement, and the control study used traditional alignment manual total knee replacement. The knee society score (KSS), Hip-knee-ankle(HKA) angle, mechanical lateral distal femoral angle(mLDFA), mechanical medial proximal tibial angle(mMPTA), sagittal femoral component angle(SFCA), range of motion(ROM), WOMAC score, SF-36, Visual Analogue Scale(VAS score), surgical time, blood loss, and complications are evaluated and compared.
