摘要

目的选择合适的股骨和胫骨假体尺寸是全膝关节置换术(TKA)的重要步骤。在进行双侧TKA时,通常认为与对侧相同大小的假体就足够了,尽管有报道称两侧解剖结构存在差异。在这项研究中,我们量化了中东人群分阶段双侧TKA中股骨和胫骨假体大小不对称的发生率。方法回顾性观察研究2013年1月至2019年1月在同一研究所由两名外科医生接受相同类型假体的无并发症双侧TKA的所有患者。结果123例患者中,股骨和胫骨假体大小变化分别为42例(34.1%)和30例(24.4%)。在后路置换(PS)和十字保留(CR)设计中,差异都很明显。在PS和CR两种设计中,股骨假体在两侧之间的尺寸差异都大于胫骨假体。PS亚组和CR亚组股骨假体大小的变化百分比相似(分别为32.7%和33.3%)。然而,对于胫骨假体,PS设计的尺寸变化(24.5%)高于cr7设计(18.7%)。7.3%的患者在股骨和胫骨的两侧有2个或更多的大小变化。结论双侧全髋关节置换术患者股骨和胫骨假体的大小变化是常见的。对侧组件尺寸不应作为另一侧组件尺寸的决定因素。

Component asymmetry in bilateral total knee arthroplasty in the middle eastern population

Purpose

Proper sizing of the femoral and tibial components is an important step in total knee replacement (TKA). When performing bilateral TKA, there is often an opinion that the same size prosthesis as the opposite side will suffice, even though there are reports of anatomical differences between sides. In this study, we quantify the incidence of asymmetry in femoral and tibial component sizes in staged bilateral TKA in a Middle East population.

Methods

This is a retrospective observational study of all patients who underwent uncomplicated bilateral TKA with the same type of prosthesis by two surgeons at the same institute, between January 2013 and January 2019.

Results

There were 123 patients, femoral and tibial component size variationswerepresent in 42patients (34.1%) and 30 patients (24.4%) respectively. The variation was evident in both posterior substituting (PS) and cruciate retaining (CR) designs. The femoral components had a higher variation in size between the sides for both PS and CR designs than the tibial components for both designs. The percentage variation in the size of the femoral component was similar for PS and CR subgroups (32.7% and 33.3% respectively). However, for the tibial component, the size variation was higher for PS design (24.5%) than for CRdesign (18.7%). 7.3% had a side-to-side variation by 2 or more sizes in both femoral and tibial components.

Conclusion

Variations in the size of the femoral and tibial components is common in patients undergoing bilateral TKA. Contralateral component size should not be used as the determinant of component sizes on the other side.

期刊介绍: Journal of Arthroscopy and Joint Surgery (JAJS) is committed to bring forth scientific manuscripts in the form of original research articles, current concept reviews, meta-analyses, case reports and letters to the editor. The focus of the Journal is to present wide-ranging, multi-disciplinary perspectives on the problems of the joints that are amenable with Arthroscopy and Arthroplasty. Though Arthroscopy and Arthroplasty entail surgical procedures, the Journal shall not restrict itself to these purely surgical procedures and will also encompass pharmacological, rehabilitative and physical measures that can prevent or postpone the execution of a surgical procedure. The Journal will also publish scientific research related to tissues other than joints that would ultimately have an effect on the joint function.
