The Columbus knee system is designed as a standard knee implant to allow high flexion without additional bone resection. Between August, 2004 and March, 2010 we performed 109 total knee arthroplasties of the Columbus knee system in 101 consecutive patients suffering from primary arthrosis of the knee. Mean age was 72.4 years in women and 70.3 years in men. Mean followup was 47.3 months. The 4-year results of a group of patients who received the NexGen Full Flex implant operated by the same surgeon were used for comparison. Mean total knee score was Columbus: 175.6 and NexGen Flex: 183.4; P = 0.037. Mean operation time was 53 min for Columbus and 66 min for NexGen Flex; P < 0.001. With new streamlined instruments operative time became 60 min for the Columbus; P > 0.05. Radiological assessment showed no signs of loosening for both groups. Therefore, the Columbus knee system can be recommended for flexion angles up to 140°.
哥伦布膝关节系统被设计为一种标准的膝关节植入物，可在不进行额外骨切除的情况下实现高屈曲度。在2004年8月至2010年3月期间，我们对101例连续性原发性膝关节骨关节炎患者进行了109例哥伦布膝关节系统全膝关节置换术。女性平均年龄为72.4岁，男性为70.3岁。平均随访时间为47.3个月。将一组由同一位外科医生操作的接受NexGen全屈曲植入物的患者的4年结果用于比较。哥伦布膝关节系统的平均全膝关节评分为175.6分，NexGen Flex为183.4分；P = 0.037。哥伦布膝关节系统的平均手术时间为53分钟，NexGen Flex为66分钟；P < 0.001。使用新的简化器械后，哥伦布膝关节系统的手术时间变为60分钟；P > 0.05。放射学评估显示两组均无松动迹象。因此，对于屈曲角度达140°的情况，哥伦布膝关节系统是可以推荐使用的。
