Case Report

Robotic Arm-Assisted Total Knee Arthroplasty in the Setting of Combined Extra-articular Deformities of the Femur and Tibia

Figure 2

(a) Significant ligament imbalance was demonstrated between flexion and extension even after soft tissue release and removal of ACL and osteophytes. (b) The numbers in the right lower corner demonstrate ligament balance in knee flexion after making the tibial cut and moving the femoral component anteriorly and before rotating the femoral component internally. (c) The final ligament balance was demonstrated in knee flexion and extension after femoral component ration with implants.
