Abstract

Background and purpose: Periprosthetic knee fractures (PPKFs) can be a serious complication after total knee arthroplasty (TKA). We aimed to compare patient-reported outcome (PRO) scores reported between 1 and 4 years after PPKF with a matched uncomplicated TKA control group.

Methods: This nationwide cross-sectional matched cohort study included 372 TKA patients with a PPKF occurring from 2019 to 2022 and a control group of 878 uncomplicated TKA patients matched by age, time since TKA, and sex. The study population was derived from the Danish National Patient Register. The patients received questionnaires regarding knee function, quality of life, pain and satisfaction in 2023. The questionnaires included Oxford Knee Score (OKS), the Forgotten Joint Score (FJS), and the EQ-5D-5L Index.

Results: The response rate was 48%. Mean OKS was 7 (confidence interval [CI] 5-9) points lower after a PPKF with a score of 30 (standard deviation [SD] 11) in the PPKF group vs 37 (SD 11) in the control group. The FJS was 13 (CI 7-19) points lower after a PPKF with a score of 50 (SD 30) in the PPKF group vs 63 (SD 30) in the control group. Mean EQ-5D-5L Index scores were 0.17 (CI 0.12-0.22) lower after a PPKF with a score of 0.68 (SD 0.25) in the PPKF group vs 0.85 (SD 0.25) in the control group. Additional analysis of patients who completed PROMs 1-2 years compared with 3-4 years after PPKF showed better PRO scores after 3-4 years with an OKS of 32 (SD 12) vs 27 (SD 12), FJS 55 (SD 32) vs 43 (SD 32), and EQ-5D-5L Index of 0.74 (SD 0.34) vs 0.60 (SD 0.34).

Conclusion: Following PPKF, patients reported worse knee function, more pain, lower satisfaction, and poorer quality of life than those with uncomplicated TKAs.

膝关节假体周围骨折后1至4年患者报告的结果：一项全国性的横断面匹配研究。

背景与目的：膝关节假体周围骨折（PPKFs）是全膝关节置换术（TKA）后的严重并发症。我们的目的是比较PPKF后1至4年报告的患者报告结局（PRO）评分与匹配的无并发症TKA对照组。方法：这项全国性的横断面匹配队列研究包括372例2019年至2022年发生PPKF的TKA患者和878例无并发症TKA患者的对照组，这些患者按年龄、TKA发生时间和性别进行匹配。研究人群来自丹麦国家患者登记册。患者于2023年接受关于膝关节功能、生活质量、疼痛和满意度的问卷调查。问卷包括牛津膝关节评分（OKS）、遗忘关节评分（FJS）和EQ-5D-5L指数。结果：有效率为48%。PPKF组在PPKF评分为30（标准差[SD] 11）后，平均OKS比对照组低7（置信区间[CI] 5-9）点（标准差[SD] 11）。PPKF组在PPKF评分为50分（SD 30）后，FJS比对照组低13分（CI 7-19），对照组为63分（SD 30）。PPKF组EQ-5D-5L指数平均评分0.17 (CI 0.12-0.22)， PPKF组评分0.68 (SD 0.25)，对照组评分0.85 （SD 0.25）。对PPKF后1-2年与3-4年完成PROMs的患者的进一步分析显示，3-4年完成PROMs的患者的PRO评分更好，OKS为32 (SD 12) vs 27 (SD 12)， FJS为55 (SD 32) vs 43 (SD 32)， EQ-5D-5L指数为0.74 (SD 0.34) vs 0.60 （SD 0.34）。结论：与未合并tka的患者相比，PPKF患者的膝关节功能更差，疼痛更多，满意度更低，生活质量更差。
