Eligibility

Inclusion criteria

Inclusion criteria: All patients eligible for Bilateral simultaneous total knee arthroplasty for primary OA of the knee joint These patients are consented for participation in this RCT, in which they will receive robotic-arm assisted total knee replacement surgery with different alignment strategies in both the knees (i.e one knee randomized to receive TKR with FUNCTIONAL ALIGNMENT, and the second knee to receive TKR with MECHANICAL ALIGNMENT)

Exclusion criteria

Exclusion criteria: Post-traumatic arthritis Asymmetrical knee deformities Unwilling to participate in the trial
