Remarkable results were demonstrated for the nonlinked, semiconstrained total condylar knee prosthesis in the first long-term follow-up study. The posterior cruciate condylar prosthesis, a variation of the basic design, leaves the posterior cruciate ligament intact. Ninety-four consecutive knees were observed for a minimum postoperative follow-up period of five years. Apart from this design modification and a slightly different program of postoperative care, the methods and techniques used were identical to those used with the total condylar knee prosthesis. By the same method of assessment (The Hospital for Special Surgery Knee Rating Scale), 54 of the ninety-four knees (57.4%) were rated excellent; 37 (39.4%), good; two (2.1%), fair; and one (1.0%), poor. The average preoperative score was 48 points, and the average postoperative score was 81 points (85-100 points = excellent). The posterior cruciate condylar total knee prosthesis represents an excellent prosthetic design for a wide variety of knee deformities and maintains the posterior cruciate ligament for supplementary posterior support.
在第一项长期随访研究中，非铰链式、半限制性全髁膝关节假体显示出了显著的效果。后交叉髁假体是基本设计的一种变体，保留了后交叉韧带的完整。连续观察了94例膝关节，术后随访期至少为5年。除了这种设计改进和术后护理方案略有不同外，所使用的方法和技术与全髁膝关节假体相同。采用相同的评估方法（特种外科医院膝关节评分量表），94例膝关节中有54例（57.4%）被评为优秀；37例（39.4%）为良好；2例（2.1%）为中等；1例（1.0%）为差。术前平均评分为48分，术后平均评分为81分（85 - 100分为优秀）。后交叉髁全膝关节假体是一种针对多种膝关节畸形的优秀假体设计，并保留后交叉韧带以提供额外的后方支撑。
