A mobile-bearing element, metal-backed, interchangeable knee replacement system has been designed to combine low constraint forces with low contact stresses (LCS), allowing nearly normal joint articulation and loading as well as long-term wear resistance of the implants. The system is versatile, including a large number of component options in variable sizes, and it may be used in both primary and revision arthroplasties. The overall results in the first 123 cemented cases (97 patients) with 2- to 7-year follow-up (average 3.7 years) were good to excellent in 88.6%, fair in 3.3%, and poor in 8.1%. Fair and poor results were seen predominantly in multiply operated and implant revision cases. The best results were noted in primary cases, 97.4% of which had good to excellent results. There have been no mechanical implant failures and no meniscal bearing dislocations in this series. Pain relief and restoration of function have been very gratifying with this system.
一种金属背衬的、可互换的活动轴承式膝关节置换系统被设计成将低约束力与低接触应力（LCS）相结合，允许植入物实现近乎正常的关节活动和负荷以及长期耐磨性。该系统用途广泛，包括大量不同尺寸的组件选项，可用于初次和翻修关节成形术。对123例采用骨水泥固定的病例（97名患者）进行2至7年的随访（平均3.7年），总体结果显示，88.6%为优至良，3.3%为一般，8.1%为差。一般和差的结果主要出现在多次手术和植入物翻修病例中。初次病例的结果最佳，其中97.4%为优至良。该系列中未出现植入物机械故障和半月板轴承脱位情况。使用该系统后，疼痛缓解和功能恢复情况非常令人满意。
