This study compares the fixed-bearing PFC Sigma Total Knee Arthroplasty to the recently introduced rotating-platform version of the same design in 26 patients. At an average follow-up time of 46 months for the fixed-bearing side and 16 months for the rotating-platform side, no significant differences were found in terms of knee preference, knee pain, range of motion, overall satisfaction, or Knee Society scores (KSSs). No revisions, subluxations, dislocations, or infections were seen. Also no radiographic evidence of component loosening, osteolysis, or malalignment was found in any knee. The results of cementing the PFC Sigma rotating-platform, posterior-stabilized total knee show excellent patient satisfaction at 1 year and comparable clinical and radiographic results to the fixed-bearing version.
本研究对26例患者的固定平台PFC Sigma全膝关节置换术与同一设计的最近推出的旋转平台版本进行了比较。固定平台侧平均随访时间为46个月，旋转平台侧为16个月，在膝关节偏好、膝关节疼痛、活动范围、总体满意度或膝关节协会评分（KSS）方面未发现显著差异。未观察到翻修、半脱位、脱位或感染情况。在任何膝关节中也未发现假体松动、骨溶解或排列不齐的影像学证据。PFC Sigma旋转平台后稳定型全膝关节置换术的骨水泥固定结果显示，患者1年时的满意度极佳，临床和影像学结果与固定平台版本相当。
