Figure 5From: Distal femoral condyle is more internally rotated to the patellar tendon at 90° of flexion in normal kneesSchematic figures of the distal femur and the proximal tibia at a knee flexion angle of 90° seen from the ankle joint. (A) Preoperative condition. The tangent of the most distal part of femoral condyles (broken line) was internally rotated relative to the patellar tendon (solid line). (B) Postoperative condition with the symmetric femoral component. The tangent of the most distal part of the symmetric femoral component (bold solid line) would be more internally rotated relative to the patellar tendon (thin solid line).Back to article page
