Total knee arthroplasty in Ranawat II valgus deformity with enlarged femoral valgus cut angle: A new technique to achieve balanced gap

Figure 1 Process of total knee arthroplasty. A: Preoperative X-ray of the knee joint in anterior and lateral position; B: The distal femoral valgus osteotomy angle was 7° (red arrow); C: The thickness of the medial femoral condyle osteotomy was more than that of the lateral condyle; D: Tibial plateau osteotomy was taken as the medial tibial plateau reference; E: The osteophyte of the lateral tibial plateau was removed, and the lateral plateau bone defect (black circle) was visible; F: Release of the lateral collateral ligament; G: The thickness of distal femoral osteotomy was increased because the extension space was smaller than the flexion space; H: Postoperative X-ray of the knee joint in anterior and lateral position.
