The results of 18 matched pairs of Porous Coated Anatomic knee prostheses were studied to compare the early clinical and functional performance of cemented versus uncemented fixation with an average five-year follow-up period for both. The knee score improved from a preoperative average of 35 points to a postoperative average of 90 points in the cemented group, and from 38 points to 93 points in the uncemented group. In particular, the individual pain scores and the range-of-motion values were well matched at the three-, six-, and 12-month follow-up visits and showed a steady improvement. Subjectively, all patients were pleased with the results of surgery; one-third preferred the cemented side, one-third preferred the uncemented side, and one-third found no difference in the performance of either knee. The clinical and functional performance of knee prostheses in patients who had one cemented knee and one uncemented knee were comparable and possibly unrelated to the type of fixation method.
对18对匹配的多孔涂层解剖型膝关节假体进行了研究，以比较骨水泥固定和非骨水泥固定的早期临床和功能表现，两组均进行了平均五年的随访。骨水泥固定组的膝关节评分从术前平均35分提高到术后平均90分，非骨水泥固定组从38分提高到93分。特别是，在术后3个月、6个月和12个月的随访中，个体疼痛评分和活动范围值匹配良好，并呈稳步改善。主观上，所有患者对手术结果都很满意；三分之一的患者更喜欢骨水泥固定的一侧，三分之一的患者更喜欢非骨水泥固定的一侧，三分之一的患者认为两侧膝关节的表现没有差异。一侧膝关节采用骨水泥固定而另一侧采用非骨水泥固定的患者，其膝关节假体的临床和功能表现相当，可能与固定方法类型无关。
