Robotic-Assisted Total Knee Arthroplasty for Distal Femur Fracture with Lateral Knee Osteoarthritis

Figure 4

Patient-specific planning. (a) A varus/valgus stress test was performed with a manual max through a full range of motion. (b) The medial gap was enlarged with flexion, and mild lateral contracture was observed. Due to reduction as much medial looseness from extension to flexion and lateral contracture from extension to midflexion, femoral and tibial components were performed in valgus alignment and we fine-tuned the amount of osteotomy. (c) Medial and lateral gaps became constant.
