BACKGROUND
Patient-specific instrument (PSI) may theoretically make total ankle arthroplasty (TAA) more accurate. Several studies have reported the outcomes of PSI TAA. The aim of this study is to systematically review the literature of PSI TAA.
METHODS
PubMed, Embase, Web of Science, and Cochrane Library databases were systematically reviewed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines for PSI TAA. The quality of the included studies was evaluated according to Methodological Index for Non-Randomized Studies (MINORS).
RESULT
Nine articles were ultimately included in the systematic review. The implant position and function outcome of TAA was similar between PSI and SI. Prediction accuracy of implant size remained great difference. PSI can shorten the operative time and fluoroscopy time. The quality of current studies on PSI TAA is insufficient to produce high-level evidence.
CONCLUSION
PSI can get similar implant position and clinical outcome in TAA compared to SI, but current evidence is not strong enough to evaluate PSI TAA.
背景
定制型器械（PSI）理论上可使全踝关节置换术（TAA）更精确。多项研究报告了PSI辅助TAA的结果。本研究旨在系统评价PSI辅助TAA的文献。
方法
根据系统评价和Meta分析的首选报告项目（PRISMA）指南，对PubMed、Embase、科学网和Cochrane图书馆数据库进行系统评价，以获取PSI辅助TAA的相关文献。根据非随机研究的方法学指标（MINORS）评估纳入研究的质量。
结果
最终9篇文章被纳入系统评价。PSI组和传统器械组（SI）的TAA植入物位置和功能结果相似。植入物尺寸的预测准确性仍存在很大差异。PSI可缩短手术时间和透视时间。目前关于PSI辅助TAA的研究质量不足以产生高级别证据。
结论
与传统器械相比，PSI在TAA中可获得相似的植入物位置和临床结果，但目前的证据不足以评估PSI辅助TAA。
