BACKGROUND
Various sizes of implants need to be available during surgery. The purpose of this paper is to compare body height and shoe size with implant sizes in patients who underwent total knee replacement surgery to see which biomarker is a better predictor for preoperative planning to determine implant size.
METHODS
A total of 100 knees, belonging to 50 females and 50 males, were observed. Participants' body height and shoe size were collected and correlated to implant sizes of a current, frequently used, standard total knee replacement (TKR) implant. The femoral anteroposterior and mediolateral width and the tibial anteroposterior and mediolateral width were correlated with height and shoe size.
RESULTS
The correlation between shoe size and the four knee implant dimensions, femoral AP, ML, and tibial AP and ML were higher than the correlations between height and the same four dimensions.
CONCLUSION
The results indicated that shoe size is a better predictor of component dimensions than is body height. III.
背景
手术过程中需要准备各种尺寸的植入物。本文旨在比较接受全膝关节置换手术患者的身高和鞋码与植入物尺寸，以确定哪种生物标志物更适合用于术前规划植入物尺寸。
方法
共观察了100个膝关节，其中50例女性和50例男性。收集参与者的身高和鞋码，并将其与当前常用的标准全膝关节置换（TKR）植入物的尺寸进行关联。测量股骨前后径和内外侧宽度以及胫骨前后径和内外侧宽度，并与身高和鞋码进行相关性分析。
结果
鞋码与四个膝关节植入物尺寸（股骨前后径、内外侧径以及胫骨前后径、内外侧径）之间的相关性高于身高与相同四个尺寸之间的相关性。
结论
结果表明，鞋码比身高更能准确预测植入物尺寸。
