A prospective study was performed of 41 consecutive revisions using a modular total knee arthroplasty design. The Hospital for Special Surgery knee score improved from 52 +/- 16 preoperatively, to 85 +/- 8 at last evaluation. At last evaluation, the HSS knee scores were excellent in 26, good in 14, fair in 1, and poor in 0 knees. The Knee Society pain score improved from 38 +/- 23 preoperatively to 91 +/- 8 at last evaluation. The Knee Society function score improved from 40 +/- 24 preoperatively to 68 +/- 28 at last evaluation. Incomplete radiolucent lines were seen adjacent to 61% of the components, but not adjacent to the long stems. The results were similar with either pressed fit or cemented long stems or posterior cruciate retaining or posterior stabilized articulations of the prosthetic design. Modularity facilitates revision total knee arthroplasty.
对连续41例采用模块化全膝关节置换设计的翻修手术进行了前瞻性研究。特种外科医院膝关节评分从术前的52±16提高到最后一次评估时的85±8。在最后一次评估时，HSS膝关节评分26例为优，14例为良，1例为中，0例为差。膝关节协会疼痛评分从术前的38±23提高到最后一次评估时的91±8。膝关节协会功能评分从术前的40±24提高到最后一次评估时的68±28。61%的假体组件附近可见不完全透光线，但长柄附近未见。无论是压配或骨水泥固定长柄，还是假体设计中的后交叉韧带保留或后稳定关节，结果相似。模块化有助于全膝关节置换翻修手术。
