BACKGROUND
Computer-assisted navigation (CAS) was developed to improve the surgical accuracy and precision. Many studies demonstrated better alignment in the coronal plane in CAS TKA compared to conventional technique. The influence on the functional outcome is still unclear. Only few studies report long-term results of CAS TKA. This study was initiated to investigate 10-year patient-reported outcome of CAS and conventional TKA.
METHODS
From initially 80 patients of a randomized study of CAS and conventional TKA a total of 50 patients could be evaluated at the 10-year follow-up. The Knee Society Score and EuroQuol Questionnaire were assessed. For all patients a competing risk analysis for revision was performed.
RESULTS
The patient-reported outcome measures demonstrated similar values for both groups. The 10-year risk for revision was 2.5% for conventional TKA and 7.5% for CAS TKA (p=0.237).
CONCLUSIONS
There was no difference between CAS and conventional TKA with regard to patient-reported outcome and revision risk ten years after surgery.

背景
计算机辅助导航（CAS）的开发是为了提高手术的准确性和精度。许多研究表明，与传统技术相比，CAS TKA 在冠状面的对线更好。但其对功能结果的影响仍不清楚。只有少数研究报告了 CAS TKA 的长期结果。本研究旨在调查 CAS 和传统 TKA 术后 10 年的患者报告结果。
方法
从最初的 80 例 CAS 和传统 TKA 的随机研究患者中，共有 50 例患者可在 10 年随访时进行评估。评估了膝关节学会评分和欧洲五维健康量表问卷。对所有患者均进行了翻修的竞争风险分析。
结果
两组患者报告的结果测量值相似。传统 TKA 的 10 年翻修风险为 2.5%，CAS TKA 的翻修风险为 7.5%（p=0.237）。
结论
在术后 10 年，患者报告的结果和翻修风险方面，CAS 和传统 TKA 之间没有差异。
