AIMS
To determine whether the size of the prostheses used in revision knee arthroplasty may be accurately and reproducibly predicted using analogue or digital pre-operative templating techniques.
METHODS
Pre-operative radiographs were templated using analogue radiographs and acetate templates, digital radiographs and acetate templates and digital radiographs and digital templating software.
RESULTS
Overall accuracy of predicting the size of implant used at surgery was 44%. There was no significant difference in the accuracy of the various templating techniques (p = 0.098).
CONCLUSIONS
Templating in revision knee arthroplasty is neither of suitable accuracy nor reliability enough to safely recommend its use for implant size prediction.
目的
确定使用模拟或数字术前模板技术能否准确且可重复地预测翻修膝关节置换术中所用假体的尺寸。
方法
使用模拟X线片和醋酸盐模板、数字X线片和醋酸盐模板以及数字X线片和数字模板软件对术前X线片进行模板测量。
结果
预测手术中所用植入物尺寸的总体准确率为44%。各种模板技术的准确率无显著差异（p = 0.098）。
结论
翻修膝关节置换术中的模板测量在准确性和可靠性方面均不足以安全地推荐用于预测植入物尺寸。
