At 6 months and 12 months postoperatively, there was no significant difference between GR and MR group in all subscales of KOOS, Table showed the KOOS at baseline, 6 month and 12 months postoperatively Showed KOOS score in symptom, pain, activities of daily living (ADL), sport and recreation function, and quality of life (QOL) between gradually reducing radius (GR) vs multi-radius (MR) femoral component TKAshowed mean change in KOOS scores between GR and MR group at 6 and 12 months from baseline51.53 ± 13.50(46.48–56.57)52.56 ± 14.88(47.00–58.11)56.96 ± 11.12(52.8–61.1)57.50 ± 115.84(51.58–63.41)48.37 ± 13.67(43.26–53.47)47.05 ± 15.45(41.27–52.81)51.25 ± 12.04(46.75–55.74)50.10 ± 13.54(45.0–55.15)38.36 ± 14.39(32.98–43.73)40.00 ± 15.88(34.07–45.93)43.01 ± 13.50(37.96–48.05)43.14 ± 15.20(37.46–48.81)47.17 ± 13.04(42.29–52.04)48 ± 11.72(43.62–52.37)57 ± 11.64(52.65–61.35)57.67 ± 8.68(54.42–60.90)65.21 ± 11.69(60.84–69.57)66.88 ± 12.19(62.32–71.42)74.58 ± 10.37(70.71–78.45)74.17 ± 9.10(70.77–77.56)showed performance-based tests from preoperative TKA, 6 months post TKA, and 12 months post TKAAll patients in this trial had a genu varus and flexion contracture deformity with the HKA of 168° ± 5° and 168° ± 6° for GR and MR group ( Showed degrees of knee motions and degrees of motion gain after 6 and 12 months postoperatively between GR and MR group
