Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
The group that the sagittal flexion angle of the femoral component less than 4°
The patients' knees were taken on the X-ray examination after the total knee arthroplasty on the medial-lateral position. The flexion (positive degree) or extension (negative degree) angle of the femoral component according to the anterior femoral cortex was measured. The patients with the sagittal flexion angle of the femoral component less than 4° were categorized into this group.
total knee arthroplasty
The surgeries were performed under general anesthesia. The medial parepatellar incision was introduced during the TKA. The femoral component size was selected according to the intro-operative measurement. The osteotomy was done according to the intramedullary guide and the cutting guide. After the proximal tibial osteotomy was finished, the cruciate-retaining Total Knee System was used. The lateral rotation of the femoral component was determined by the gap-balancing technique.
