The Scandinavian Total Ankle Replacement (STAR) has been used widely in Europe and more recently in the United States. We studied the results of the single-coated and the double-coated STAR with long-term follow-up.
All STARs (n = 324) used in Sweden (first implanted in 1993) were included. Prosthetic survival was estimated according to Kaplan-Meier.
The 14-year survival of the single-coated STAR was 0.47 (95% confidence interval [CI], 0.38-0.66), and the 12-year survival of the double-coated STAR was 0.64 (95% CI, 0.57-0.71). Women younger than 60 years with osteoarthritis had a statistically significantly higher risk of revision than men and than patients with other diagnoses.
The long-term results of the STAR prosthesis are not encouraging. The results seem to deteriorate by time.
Level IV, retrospective case series.
斯堪的纳维亚全踝关节置换术（STAR）在欧洲已被广泛使用，最近在美国也开始应用。我们对单涂层和双涂层STAR进行了长期随访研究其结果。
纳入瑞典使用的所有STAR（n = 324，首次植入时间为1993年）。根据Kaplan-Meier法估计假体生存率。
单涂层STAR的14年生存率为0.47（95%置信区间[CI]，0.38 - 0.66），双涂层STAR的12年生存率为0.64（95% CI，0.57 - 0.71）。60岁以下患骨关节炎的女性进行翻修的风险在统计学上显著高于男性以及患有其他诊断疾病的患者。
STAR假体的长期结果并不乐观。结果似乎随时间推移而恶化。
IV级，回顾性病例系列研究。
