Ninety-six uncemented total knee arthroplasties done using the Tricon-M prosthesis were followed for longer than 2 years. The implant has a multilevel porous surface to facilitate biologic ingrowth and flanged polyethylene pegs for immediate fixation. Each patient was matched for age, body habitus, and diagnosis to a patient with a cemented total knee arthroplasty. There was no statistical difference between the matched pairs as related to pain, eventual range of motion, stability, or patient satisfaction; the uncemented group did as well clinically as the cemented group. Subsidence of the tibial component was noted in cases of obese patients taking systemic corticosteroids and in whom there was inadequate coverage of the cut tibial plateau surface. The mean 2-year Hospital for Special Surgery rating score was 81 in the osteoarthritis group and 83 in the rheumatoid arthritis group.
对采用Tricon - M假体进行的96例非骨水泥型全膝关节置换术患者进行了超过2年的随访。该植入物具有多级多孔表面以促进生物向内生长，以及用于即刻固定的带凸缘聚乙烯钉。将每位患者在年龄、体型和诊断方面与行骨水泥型全膝关节置换术的患者进行匹配。在疼痛、最终活动范围、稳定性或患者满意度方面，匹配对之间无统计学差异；非骨水泥组在临床效果上与骨水泥组一样好。在肥胖且服用全身性皮质类固醇以及胫骨平台表面覆盖不足的患者中，观察到胫骨组件有下沉现象。骨关节炎组的平均2年特种外科医院评分在骨关节炎组为81分，类风湿关节炎组为83分。
