Abstract

Background: A gradually reducing radius (GRADIUS) design implant can facilitate a smooth transition from stability through full range of motion in total knee arthroplasty (TKA). Nonetheless, patient-specific factors associated with good knee flexion remain unclear.

Objective: This study aimed to determine the factors associated with good knee flexion after cruciate-retaining TKA with a GRADIUS prosthesis in an Asian population.

Methods: This retrospective study included 135 patients that were stratified according to postoperative knee flexion angle (KFA) into Group F (⩾ 120∘; 85 patients [63.2%]) and Group NF (< 120∘; 50 patients [36.8%]).

Results: Patients in Group F were taller and had a lower body mass index (BMI) smaller preoperative hipkneeankle angle and better preoperative extension and flexion angle than Group NF patients. The multivariable analysis revealed that patients' height (odds ratio [OR]: 1.07, P= 0.0150), BMI (OR: 0.85, P= 0.0049), and preoperative flexion angle (OR: 1.06, P= 0.0008) predicted good KFA. The ROC curve analysis showed that the cutoff values of a good KFA were height 155.1 cm, BMI 22.1 kg/m2, and preoperative KFA 120∘.

Conclusions: Patient height, BMI, and preoperative KFA were independent factors affecting good postoperative KFA in patients of Asian descent who underwent cruciate-retaining TKA with a GRADIUS design.

采用 GRADIUS 设计的十字韧带固定全膝关节置换术后，患者身高是膝关节术后良好屈曲的预测因素。

背景：在全膝关节置换术（TKA）中，逐渐缩小桡骨（GRADIUS）设计的假体可促进从稳定到完全活动范围的平稳过渡。然而，与膝关节良好屈曲相关的患者特异性因素仍不清楚：本研究旨在确定在亚洲人群中使用 GRADIUS 假体进行十字韧带固定 TKA 后膝关节良好屈曲的相关因素：这项回顾性研究纳入了 135 名患者，根据术后膝关节屈曲角度（KFA）将其分为 F 组（⩾ 120∘；85 名患者 [63.2%]）和 NF 组（< 120∘；50 名患者 [36.8%]）：与NF组患者相比，F组患者身高更高、体重指数（BMI）更低、术前髋膝关节角度更小、术前伸屈角度更好。多变量分析显示，患者的身高（几率比 [OR]：1.07，P= 0.0150）、体重指数（OR：0.85，P= 0.0049）和术前屈曲角度（OR：1.06，P= 0.0008）预示着良好的 KFA。ROC 曲线分析显示，良好 KFA 的临界值为身高 155.1 厘米、体重指数 22.1 千克/平方米和术前 KFA 120∘：结论：对于采用 GRADIUS 设计接受十字韧带固定 TKA 手术的亚裔患者而言，患者身高、体重指数和术前 KFA 是影响术后 KFA 优良率的独立因素。

期刊介绍： Technology and Health Care is intended to serve as a forum for the presentation of original articles and technical notes, observing rigorous scientific standards. Furthermore, upon invitation, reviews, tutorials, discussion papers and minisymposia are featured. The main focus of THC is related to the overlapping areas of engineering and medicine. The following types of contributions are considered: 1.Original articles: New concepts, procedures and devices associated with the use of technology in medical research and clinical practice are presented to a readership with a widespread background in engineering and/or medicine. In particular, the clinical benefit deriving from the application of engineering methods and devices in clinical medicine should be demonstrated. Typically, full length original contributions have a length of 4000 words, thereby taking duly into account figures and tables. 2.Technical Notes and Short Communications: Technical Notes relate to novel technical developments with relevance for clinical medicine. In Short Communications, clinical applications are shortly described. 3.Both Technical Notes and Short Communications typically have a length of 1500 words. Reviews and Tutorials (upon invitation only): Tutorial and educational articles for persons with a primarily medical background on principles of engineering with particular significance for biomedical applications and vice versa are presented. The Editorial Board is responsible for the selection of topics. 4.Minisymposia (upon invitation only): Under the leadership of a Special Editor, controversial or important issues relating to health care are highlighted and discussed by various authors. 5.Letters to the Editors: Discussions or short statements (not indexed).
