Between 1982 and 1997, 403 consecutive patients (522 elbows) with rheumatoid arthritis underwent Souter-Strathclyde total elbow replacement. By the end of 2007, there had been 66 revisions for aseptic loosening in 60 patients. The mean time of follow-up was 10.6 years (0 to 25) The survival rates at five-, ten, 15 and 19 years were 96% (95%, confidence interval (CI) 95 to 98), 89% (95% CI 86 to 92), 83% (95% CI 78 to 87), and 77% (95% CI 69 to 85), respectively. The small and medium-sized short-stemmed primary humeral components had a 5.6-fold and 3.6-fold risk of revision for aseptic loosening respectively, compared to the medium-sized long-stemmed component. The small and medium-sized all-polyethylene ulnar components had respectively a 28.2-fold and 8.4-fold risk of revision for aseptic loosening, compared to the metal-backed ulnar components. The use of retentive ulnar components was not associated with an increased risk of aseptic loosening compared to non-retentive implants.
1982年至1997年间，403例（522个肘关节）类风湿性关节炎患者连续接受了苏特-斯特拉斯克莱德全肘关节置换术。到2007年底，60例患者因无菌性松动进行了66次翻修手术。平均随访时间为10.6年（0至25年）。5年、10年、15年和19年的生存率分别为96%（95%置信区间（CI）95至98）、89%（95%CI 86至92）、83%（95%CI 78至87）和77%（95%CI 69至85）。与中型长柄肱骨干假体相比，小型和中型短柄肱骨干假体无菌性松动翻修风险分别高5.6倍和3.6倍。与金属背衬尺骨假体相比，小型和中型全聚乙烯尺骨假体无菌性松动翻修风险分别高28.2倍和8.4倍。与非保留型植入物相比，使用保留型尺骨假体与无菌性松动风险增加无关。
