PURPOSE
Introduced in the market in 1990 by Ceraver (France), the posterior-stabilised (PS) Hermes prosthesis has limited literature regarding long-term survivability. The purpose of the study is to evaluate the survival and functional outcomes of the prosthesis.
METHODS
A retrospective case series was performed including 164 patients (176 knees) having undergone total knee arthroplasty with the Hermes prosthesis between 1997 and 2000 with a follow-up period of 18 years.
RESULTS
Kaplan-Meier analysis showed a survival rate of 99.4% (95% CI. 96.0-100.0%) at 18.4 years with one revision. At final follow-up, the International Knee Society (IKS) functional score was 93.2 ± 15.6 and IKS knee score was 99.1 ± 2.5.
CONCLUSION
The Hermes PS model is a low conformity prosthesis that offers reliable durability that is comparable to other popular designs while minimizing rotational constraints and having an approachable learning curve for new users.
目的
1990 年由法国 Ceraver 公司推向市场的后稳定型（PS）Hermes 假体，其长期存活率的相关文献有限。本研究旨在评估该假体的生存率和功能结果。
方法
回顾性病例系列研究，纳入 1997 年至 2000 年间接受 Hermes 假体全膝关节置换术的 164 例患者（176 膝），随访时间为 18 年。
结果
Kaplan-Meier 分析显示，18.4 年时的生存率为 99.4%（95%可信区间，96.0-100.0%），有 1 例翻修。末次随访时，国际膝关节学会（IKS）功能评分 93.2±15.6，膝关节评分 99.1±2.5。
结论
Hermes PS 型是一种低顺应性假体，提供可靠的耐用性，与其他流行设计相当，同时最大限度地减少旋转限制，并为新用户提供易于学习的曲线。
