Abstract

Background: This retrospective study compares the outcomes of unicompartmental medial fixed-bearing knee arthroplasty (mUKA), involving a cemented metal-backed (MB) or an all-polyethylene (AP) tibial component, performed in obese patients with a body mass index (BMI) > 30 with a follow-up of at least 5 years.

Methods: The institutional database was mined for primary mUKAs involving an MB or an AP tibial component (MB-UKA and AP-UKA groups, respectively) performed from January 2015 to August 2019. Patient demographics and patient-reported outcome measures (PROMs) were compared and a propensity score matching (PSM) analysis (1:1) using multiple variables was conducted.

Results: PSM analysis yielded 37 pairs of obese MB-UKA and AP-UKA patients. At 5 years, the Knee Society Function Score (KSFS) was 75.1 ± 10.6 in MB-UKA and 79.4 ± 9.1 in AP-UKA patients (p = 0.029), and the Oxford Knee Score (OKS) was 38.1 ± 4.4 in MB-UKA and 40.6 ± 5.7 in AP-UKA patients (p = 0.011).

Conclusion: At five-year follow-up, in a matched group of obese MB-UKA and AP-UKA patients, the AP-UKA group achieved better KSFSs and OKSs. Both the AP and the MB tibial components were able to bring about a significant improvement of the most widely used PROMs.

肥胖患者接受内侧金属背板和全聚乙烯单室膝关节置换术的中期疗效：倾向匹配回顾性分析。

背景：这项回顾性研究比较了单间室内侧固定承载膝关节置换术（mUKA）的疗效，涉及骨水泥金属支撑（MB）或全聚乙烯（AP）胫骨组件，手术对象为体重指数（BMI）大于30的肥胖患者，随访至少5年：对2015年1月至2019年8月期间进行的涉及MB或AP胫骨组件的初次MUKA（分别为MB-UKA组和AP-UKA组）进行了机构数据库挖掘。比较了患者人口统计学特征和患者报告结局指标（PROMs），并使用多变量进行了倾向得分匹配（PSM）分析（1:1）：PSM分析得出了37对肥胖的MB-UKA和AP-UKA患者。5年后，MB-UKA患者的膝关节社会功能评分（KSFS）为（75.1 ± 10.6），AP-UKA患者为（79.4 ± 9.1）（P = 0.029）；MB-UKA患者的牛津膝关节评分（OKS）为（38.1 ± 4.4），AP-UKA患者为（40.6 ± 5.7）（P = 0.011）：结论：在五年的随访中，在肥胖 MB-UKA 和 AP-UKA 患者的配对组中，AP-UKA 组的 KSFS 和 OKS 更好。AP和MB胫骨组件都能显著改善最广泛使用的PROMs。

期刊介绍： Journal of Orthopaedic Surgery and Research is an open access journal that encompasses all aspects of clinical and basic research studies related to musculoskeletal issues. Orthopaedic research is conducted at clinical and basic science levels. With the advancement of new technologies and the increasing expectation and demand from doctors and patients, we are witnessing an enormous growth in clinical orthopaedic research, particularly in the fields of traumatology, spinal surgery, joint replacement, sports medicine, musculoskeletal tumour management, hand microsurgery, foot and ankle surgery, paediatric orthopaedic, and orthopaedic rehabilitation. The involvement of basic science ranges from molecular, cellular, structural and functional perspectives to tissue engineering, gait analysis, automation and robotic surgery. Implant and biomaterial designs are new disciplines that complement clinical applications. JOSR encourages the publication of multidisciplinary research with collaboration amongst clinicians and scientists from different disciplines, which will be the trend in the coming decades.
