Total knee arthroplasty (TKA) is often indicated for end-stage knee osteoarthritis management. The posterior-stabilized (PS) implant is one of the TKA implants with various component designs, including femoral component cutting jigs. However, little is known about how the differences in cutting jig designs affect the outcomes. This study aims to compare the radiographic and functional outcomes of the patients who underwent cemented TKA using all-in-one and four-in-one femoral component PS implants.
A retrospective comparative study assessed patients who underwent cemented TKA using PS implants from 2018 to 2019. The patients were divided into all-in-one and four-in-one groups. Demographic data, surgery duration, postoperative radiological findings after one week, and functional outcomes after two years were collected and compared.
A total of 96 patients were included in the study, 55 patients were in all-in-one sample, and 41 patients were in four-in-one sample. The majority of the patients in both groups were female, aged >60 years old, overweight (BMI ≥ 25), and presented with an ASA score of II. We found significantly shorter surgery duration in the all-in-one group compared to the four-in-one group (128.00 ± 36.24 vs. 210.61 ± 57.54, =0.000). The four-in-one group and the all-in-one group showed the insignificant difference in , , , and angles (=0.476, 0.273, 0.594, and 0.818). The functional outcomes (SF-12, KSS, and KOOS) showed insignificant differences.
There is no differentiation for the postsurgery functional and radiological outcomes between all-in-one and four-in-one implants.
全膝关节置换术（TKA）常用于终末期膝骨关节炎的治疗。后稳定型（PS）植入物是TKA植入物之一，有多种组件设计，包括股骨组件截骨导向器。然而，对于截骨导向器设计的差异如何影响手术结果，人们知之甚少。本研究旨在比较使用一体式和四合一式股骨组件PS植入物进行骨水泥型TKA的患者的影像学和功能结果。
一项回顾性比较研究评估了2018年至2019年使用PS植入物进行骨水泥型TKA的患者。患者分为一体式组和四合一式组。收集并比较人口统计学数据、手术时间、术后一周的放射学检查结果以及术后两年的功能结果。
本研究共纳入96例患者，一体式样本组55例，四合一式样本组41例。两组中的大多数患者为女性，年龄>60岁，超重（BMI≥25），美国麻醉医师协会（ASA）评分为II级。我们发现，与四合一式组相比，一体式组的手术时间明显更短（128.00±36.24对210.61±57.54，P=0.000）。四合一式组和一体式组在股骨髁上、髁间、胫股和髌股角方面无显著差异（P=0.476、0.273、0.594和0.818）。功能结果（SF-12、膝关节协会评分[KSS]和膝关节损伤与骨关节炎疗效评分[KOOS]）无显著差异。
一体式和四合一式植入物在术后功能和影像学结果方面无差异。
