Coronal plane stability of cruciate-retaining total knee arthroplasty in valgus gonarthrosis patients: A mid-term evaluation using stress radiographs

Figure 4 A case of a 65-year-old female with severe valgus osteoarthritis of the knee. A: The preoperative radiograph shows a valgus deviation of the mechanical axis of 22 degrees. After initial soft tissue release, persistent tightness of the lateral structure was still noted, causing an unbalanced extension gap. Thus, a lateral condylar sliding osteotomy was performed intraoperatively; B: The knee was stable after stress radiography.
