The Rotaglide knee (Cozim Medical, UK) is a three-part knee containing a mobile polyethylene meniscal platform, imparting reduced loosening forces to the tibia. The femoral component design provides a high degree of congruency throughout the range of motion from 0 degree to 110 degrees, and both femoral and tibial components ensure minimal bone removal. The system is versatile, including a large number of component options, and it may be used in both primary and revision arthroplasties. The first results in 170 cemented knees (161 patients) with 2- to 5-year follow-up periods (average, 3.1 years) were very encouraging (excellent or good in 95% of knees, based on the British Orthopaedic Association knee assessment system). Poor results were seen only in revision cases. There have been no mechanical implant failures and no platform bearing dislocations, and the platforms continue to move as documented by postoperative roentgenograms, which show the metal markers of the platforms moving anteriorly in flexion and posteriorly in extension.
Rotaglide膝关节（英国Cozim Medical公司）是一种由三部分组成的膝关节，包含一个可移动的聚乙烯半月板平台，可减少施加于胫骨的松动力。股骨部件的设计在0度至110度的整个运动范围内提供高度的贴合度，股骨和胫骨部件均确保最少的骨切除量。该系统用途广泛，包括大量的部件选项，可用于初次和翻修关节成形术。对170例采用骨水泥固定的膝关节（161例患者）进行2至5年随访期（平均3.1年）的初步结果非常令人鼓舞（根据英国骨科协会膝关节评估系统，95%的膝关节结果为优或良）。仅在翻修病例中出现了较差的结果。未发生机械性植入物故障和平台轴承脱位，术后X线片显示平台的金属标记物在屈曲时向前移动、伸展时向后移动，证明平台仍可移动。
