Comparison Between Robotic-arm Assisted Total Knee Replacement and Traditional Total Knee Replacement

Comparison Between Robotic-Arm Assisted Modified Kinematic Alignment Total Knee Replacement And Traditional Manual Alignment Total Knee Replacement：A Prospective Multicenter, Double-Blind Study

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.

Inclusion Criteria:

• age between 18 years and 85 years
• primary total knee replacement

Exclusion Criteria:

• obvious bone defect
• infection
• BMI>>35kg/m2
• severe osteoporosis
• mental disease
