Comparing Efficacy Between Restricted Kinematic Alignment vs Mechanical Alignment in Bilateral TKA

Comparison of Functional Outcomes in Restricted Kinematic Alignment and Mechanical Alignment in Robotic Assisted Simultaneous Bilateral Total Knee Arthroplasty. A Randomized Controlled Trial

The goal of this RCT is to investigate efficacy between restricted kinematic alignment and mechanical alignment TKA in simultaneous bilateral TKA patients.

The main question[s] it aims to answer are:

• Does rKA have better functional outcomes than MA in simultaneous bilateral TKA patients?
• Does rKA have lower pain score than MA in simultaneous bilateral TKA patients? Participants will undergo simultaneous bilateral TKA and randomized one side will use rKA and the other side will use MA.

Inclusion Criteria:

• Age 40-80 years
• Diagnosis bilateral primary osteoarthritis of knee joint and undergo simultaneous bilateral total knee arthroplasty
• ASA classification I-II

Exclusion Criteria:

• Valgus deformity
• BMI > 40kg/m2
• History of previous knee surgery
• Active infection of the knee joint
