Bilateral Total Knee Replacement: Robotic and Conventional

A 69-year-old woman weighing approximately 70 kg presented with bilateral knee pain, greater on the right, with impaired walking and activities of daily living. She had no reported comorbidities. Examination demonstrated bilateral medial joint-line tenderness, approximately 8° right-knee varus and 6° left-knee varus, with a range of motion of 0°–130°, no fixed flexion deformity, instability or distal neurovascular deficit. Although unicompartmental arthroplasty was initially considered for the left knee, patellofemoral and lateral-compartment involvement supported bilateral total knee arthroplasty.

1. The left knee underwent conventional TKA
2. The patella was not resurfaced
3. For the right knee
4. Final trial assessment demonstrated a balanced knee in flexion
