A comparison of the clinical and radiographic results of patients with metal-backed monoblock Insall-Burstein I and modular Insall-Burstein II Posterior Stabilized Knee Prostheses was done. The minimum followup was 10 years. The clinical results were comparable with a similar average Hospital for Special Surgery knee score of 85 and 84 points, respectively. Likewise, the Knee Society Knee and Functional Scores showed no statistical difference. Radiographically, the incidence of minor radiolucent lines was 11% for the Insall-Burstein I prostheses and 29% for the Insall-Burstein II prostheses, but their presence was of no clinical significance. There was no clinical or radiographic evidence of tibial component loosening with either prosthetic design and there were no revisions for polyethylene wear or osteolysis in either cohort of patients.
对采用金属背衬一体式Insall-Burstein I型和模块化Insall-Burstein II型后稳定型膝关节假体患者的临床和影像学结果进行了比较。最短随访时间为10年。临床结果具有可比性，平均特种外科医院膝关节评分分别为85分和84分。同样，膝关节协会膝关节和功能评分无统计学差异。影像学上，Insall-Burstein I型假体的微小透光线发生率为11%，Insall-Burstein II型假体为29%，但其存在无临床意义。两种假体设计均无胫骨组件松动的临床或影像学证据，两组患者中均无因聚乙烯磨损或骨溶解而进行的翻修手术。
