Abstract

AIM

To investigate the correlation between preoperative measurement in total knee arthroplasty and the prosthetic size implanted.

METHODS

A prospective double-blind study of 50 arthroplasties was performed. Firstly, the reliability and correspondence between the size of said measurement and the actual implant utilized was determined. Secondly, the existing correlation between the intra- and interobserver determinations with the intraclass correlation coefficient was analyzed.

RESULTS

An overall correspondence of 54%, improving up to 92% when the measured size admitted a difference of one size, was found. Good intra- and interobserver reliability with an intraclass correlation coefficient greater than 0.90 (P < 0.001) was also discovered.

CONCLUSION

Agreement between the preoperative measurement with standardized acetate templates and the prosthetic size implanted can be considered satisfactory. We thus conclude it is a reproducible technique.

摘要

目的

研究全膝关节置换术中术前测量与植入假体尺寸之间的相关性。

方法

对50例关节置换术进行前瞻性双盲研究。首先,确定上述测量尺寸与实际使用植入物之间的可靠性和对应性。其次,使用组内相关系数分析观察者内和观察者间测定值之间的现有相关性。

结果

发现总体对应率为54%,当测量尺寸允许相差一个尺寸时,对应率提高到92%。还发现观察者内和观察者间具有良好的可靠性,组内相关系数大于0.90(P < 0.001)。

结论

术前使用标准化醋酸盐模板测量与植入假体尺寸之间的一致性可认为是令人满意的。因此,我们得出结论,这是一种可重复的技术。
