This prospectively blinded randomized controlled study evaluated the difference in the functional and radiological outcomes in patients who received a press-fit condylar Sigma cemented cruciate-substituting total knee arthroplasty with either a rotating platform (RP) or a fixed bearing (FB). There were 51 joints in 49 patients: 24 joints in the RP group (mean follow-up, 43 months) and 27 joints in the FB group (mean follow-up, 40 months). At baseline, there was no significant difference in age, body mass index, preoperative diagnosis, Charnley class, range of motion, clinical and functional scores, between the RP and FB groups. At mid-term follow up both the RP and FB give equivalent results, but patients with the RP tended to have a higher activity level score.
本前瞻性盲法随机对照研究评估了在接受压配合髁 Sigma 骨水泥固定交叉韧带替代型全膝关节置换术的患者中，使用旋转平台（RP）或固定轴承（FB）的患者在功能和影像学结果方面的差异。共有 49 名患者的 51 个关节：RP 组 24 个关节（平均随访 43 个月），FB 组 27 个关节（平均随访 40 个月）。在基线时，RP 和 FB 两组在年龄、体重指数、术前诊断、Charnley 分级、活动范围、临床和功能评分方面无显著差异。中期随访时，RP 和 FB 两组的结果相当，但 RP 组患者的活动水平评分较高。
