Since 1974, we have made a prospective study in Bristol of the results of unicompartmental knee replacement using the St Georg sledge prosthesis. A total of 115 knees in 100 patients have been followed up for 2 to 12 years (mean, 4 years 9 months). Results have assessed both by the Bristol knee score and by survivorship studies on the total series of 138 knees. Results were excellent or good in 86% and fair or poor in 14%. The survivorship study (based on a definition of failure which included significant pain or a dissatisfied patient or the need for revision) showed a cumulative success rate of 76.4% at six years, with no further failures after that time. Seven knees have been revised, in most cases for deterioration of the contralateral compartment. The operation is recommended as a satisfactory and durable form of treatment for osteoarthritis affecting a single tibiofemoral compartment.
自1974年以来，我们在布里斯托尔对使用圣乔治雪橇假体进行单髁膝关节置换的结果进行了前瞻性研究。100例患者的115个膝关节接受了2至12年的随访（平均4年9个月）。通过布里斯托尔膝关节评分以及对138个膝关节的整个系列进行的生存率研究来评估结果。结果为优或良的占86%，一般或差的占14%。生存率研究（基于包括严重疼痛、患者不满意或需要翻修的失败定义）显示，六年时的累积成功率为76.4%，此后没有进一步的失败病例。七个膝关节进行了翻修，大多数情况是对侧关节间室恶化。对于影响单个胫股关节间室的骨关节炎，建议将该手术作为一种令人满意且持久的治疗方式。
