METHODS: Patients that underwent primary TKA in the study group (ATTUNE® Knee System) or control group (LCS® COMPLETE Knee System) were included in this retrospective, single-center study. EOR was defined as no complications, no readmissions, no extra outpatient visits, ≤ 48 h length of hospital stay (LOS), and restored range of motion and pain perception at 3-month follow-up. Multivariate logistic regression was used to compare EOR between the study and control groups. Results were adjusted for differences in baseline characteristics and are presented with 95% confidence intervals (CI). Data were collected from a specialized clinic for elective surgeries in the Netherlands, between January 2017 and December 2020.
RESULTS: A total of 566 patients (62.4% female, mean age 67 years) were included for analysis; 185 patients (32.7%) underwent TKA in the study group. Compared to the control group, patients in the study group had greater probability of achieving EOR (65.8% [95% CI: 55.1-75.2] vs. 38.9% [95% CI: 32.8-45.3]; p < 0.001), a LOS ≤ 48 h (77.2% [95% CI: 67.7-84.5] vs. 61.4% [95% CI: 54.7-67.7]; p < 0.05), and ideal pain perception at 3-month follow-up (93.3% [95% CI: 85.7-97.0] vs. 78.2% [95% CI: 71.0-83.9]; p < 0.05).
CONCLUSIONS: The study group was associated with a greater probability of achieving EOR versus the control group, suggesting improved quality of care.
方法:在研究组(ATTUNE®膝关节系统)或对照组(LCS®完全膝关节系统)中接受原发性TKA的患者被纳入本回顾性研究,单中心研究。EOR定义为无并发症,没有再入院,没有额外的门诊就诊,≤48小时的住院时间(LOS),并在3个月随访时恢复了运动范围和疼痛感知。采用多因素logistic回归分析比较研究组和对照组的EOR。根据基线特征的差异调整结果,并以95%置信区间(CI)表示。数据是从荷兰的选择性手术的专门诊所收集的,2017年1月至2020年12月。
结果:共有566例患者(62.4%为女性,平均年龄67岁)纳入分析;研究组185例患者(32.7%)接受了TKA.与对照组相比,研究组患者实现EOR的可能性更大(65.8%[95%CI:55.1-75.2]vs.38.9%[95%CI:32.8-45.3];p<0.001),aLOS≤48h(77.2%[95%CI:67.7-84.5]vs.61.4%[95%CI:54.7-67.7];p<0.05),3个月随访时的理想疼痛感知(93.3%[95%CI:85.7-97.0]vs.78.2%[95%CI:71.0-83.9];p<0.05)。
结论:与对照组相比,研究组实现EOR的可能性更大,建议提高护理质量。
