A consecutive prospective series of 102 knees (90 patients) had unicompartmental knee arthroplasty (St. Georg "sledge") between 1973 and 1979 for gonarthrosis, Stages 2-4. Total clinical and roentgenographical evaluation was undertaken after 5-11 years (mean, 8.1 years) and included all 75 surviving patients. Fully comparable results were encountered in the 15 patients who died during the observation period. There were no early revisions but five late revisions; two due to loosening, one late infection, one instability, and one intractable pain. Complete loosening occurred in four patients (4%). Functional score (Hospital for Special Surgery method) averaged 77 points (preoperative, 43) with no tendency of deterioration with time. Loss of initially achieved alignment was generally associated with bone resorption around the tibial component. Minor arthrotic changes of the non-operated compartment occurred in 4% of the cases.
1973年至1979年间，对102个膝关节（90例患者）进行了连续前瞻性研究，这些患者因膝关节骨性关节炎2至4期接受了单髁膝关节置换术（圣乔治雪橇型）。在5至11年（平均8.1年）后进行了全面的临床和影像学评估，纳入了所有75名存活患者。对观察期内死亡的15例患者也获得了完全可比的结果。没有早期翻修病例，但有5例晚期翻修；2例因松动，1例晚期感染，1例不稳定，1例顽固性疼痛。4例患者（4%）出现完全松动。功能评分（特种外科医院方法）平均为77分（术前为43分），且没有随时间恶化的趋势。最初获得的对线丢失通常与胫骨假体周围的骨质吸收有关。4%的病例中出现了未手术间室的轻微关节病变。
