Background:Previous studies have examined the relationship between patient resilience and functional outcome scores after anterior cruciate ligament reconstruction (ACLR). However, past studies have failed to explore the longitudinal relationship between preoperative resilience and functional outcomes 2 years after ACLR.Purpose:To evaluate the relationship between preoperative patient resilience and functional outcomes 2 years after ACLR.Study Design:Cohort study; Level of evidence, 3.Methods:Patients were identified who underwent ACLR for anterior cruciate ligament tears between January and June 2020 at a single institution. Those who completed the Brief Resilience Scale preoperatively as part of routine patient questionnaires were considered for inclusion. Patients were contacted a minimum of 2 years after ACLR to complete the short form of the Knee injury and Osteoarthritis Outcome Score (KOOS-JR), Single Assessment Numeric Evaluation (SANE), International Knee Documentation Committee (IKDC) Subjective Knee Form, and visual analog scale (VAS). Outcomes were compared among patients with low resilience (LR), normal resilience (NR), and high resilience (HR), as defined in a previous study.23Results:A total of 81 patients were included in the final analysis, with 14 patients in the low preoperative resilience group, 54 in normal, and 13 in high. The mean age of the cohort was 32.0 years, and there were no significant differences in age, sex, race, graft type, or psychiatric comorbidities among the resilience groups. Significantly increased postoperative KOOS-JR scores were observed in patients in the HR group as compared with those in the NR and LR groups (94.8, 86.7, and 79.6, respectively; P = .031). There were also significantly increased postoperative SANE scores in patients in the HR group versus those in the NR and LR groups (92.3, 83.5, and 69.2; P = .012). Patients with high preoperative resilience achieved the IKDC Patient Acceptable Symptom State at significantly higher rates ( P = .003). No significant differences were observed in postoperative VAS ( P = .364), IKDC ( P = .072), or change in IKDC ( P = .448) over time among resilience groups. Postoperatively, 30 patients (37.0%) changed resilience groups, with 13 moving down and 17 moving up in category (low, n = 12; normal, n = 55; high, n = 14).Conclusion:Preoperative resilience correlated with KOOS-JR and SANE scores 2 years after ACLR but did not correlate with VAS, IKDC, or change in IKDC over the same period. Resilience was not static, with changes in resilience observed from initial to final evaluations. Resilience is not a strong predictor of postoperative patient-reported outcomes after ACLR.

患者恢复力对前交叉韧带重建术后功能结局的影响


背景： 既往研究考察了前交叉韧带重建 （ACLR） 后患者恢复力与功能结局评分之间的关系。然而，过去的研究未能探讨 ACLR 后 2 年术前恢复力与功能结局之间的纵向关系。目的： 评估 ACLR 术后 2 年患者术前恢复力与功能结局之间的关系。研究设计： 队列研究;证据水平， 3.方法： 确定 2020年1月至6月在单一机构接受前交叉韧带撕裂 ACLR 的患者。那些在术前完成 Brief Resilience Scale 作为常规患者问卷的一部分的人被考虑纳入。ACLR 后至少 2 年联系患者完成膝关节损伤和骨关节炎结果评分 （KOOS-JR） 的简短表格、单次评估数字评估 （SANE）、国际膝关节文献委员会 （IKDC） 主观膝关节表格和视觉模拟量表 （VAS）。比较了低弹性 （LR） 、正常弹性 （NR） 和高弹性 （HR） 患者的结局，如先前研究中所定义.23结果： 最终分析共纳入 81 例患者，其中 14 例为低术前弹性组，54 例为正常，13 例为高。该队列的平均年龄为 32.0 岁，恢复力组之间在年龄、性别、种族、移植物类型或精神合并症方面没有显著差异。与 NR 组和 LR 组患者相比，HR 组患者的术后 KOOS-JR 评分显著增加 （分别为 94.8、86.7 和 79.6;P = .031）。 与 NR 和 LR 组相比，HR 组患者的术后 SANE 评分也显著增加 （92.3、83.5 和 69.2;P = .012）。具有高术前恢复力的患者以显着更高的比率达到 IKDC 患者可接受的症状状态 （P = .003）。在恢复力组之间，术后 VAS （P = .364） 、 IKDC （ P = .072） 或 IKDC 变化 （P = .448） 随时间变化未观察到显著差异。术后，30 例患者 （37.0%） 改变了恢复力组，其中 13 例下降，17 例上升 （低，n = 12;正常，n = 55;高，n = 14）。结论： 术前恢复力与 ACLR 后 2 年 KOOS-JR 和 SANE 评分相关，但与 VAS 、 IKDC 或同期 IKDC 的变化无关。弹性不是静态的，从初始评估到最终评估都观察到弹性的变化。恢复力并不是 ACLR 后患者报告结局的有力预测指标。
