Fig. 1From: Different tibial rotational axes can be applied in combination according to the tibial tuberosity–posterior cruciate ligament distance in total knee arthroplastyThree planes defined on the 3D models of the knee. Plane A (red): correlates with the tibial osteotomy plane, 8 mm distal to the center point of the lateral tibial plateau. Plane B (green): through the posterior cruciate ligament insertion at tibial condyle notch’s level. Plane C (blue): over the patellar tendon attachment’s level at tibial tuberosityBack to article page
