Background:The Banff Patellofemoral Instability Instrument 2.0 (BPII 2.0) is a disease-specific, quality of life patient-reported outcome measure (PROM) that is valid and reliable in patients with recurrent lateral patellofemoral instability (LPI). Quality of life encompasses the physical, emotional, and psychological aspects of patient functioning and recovery.Purposes:To concurrently validate the BPII 2.0 to the Tampa Scale for Kinesiophobia (TSK-11), the Pain Catastrophizing Scale (PCS), and the Anterior Cruciate Ligament–Return to Sport after Injury Scale (ACL-RSI) in patients presenting with recurrent LPI and to assess baseline values for the PROMs in patients with LPI.Study Design:Cohort study (Diagnosis); Level of evidence, 2.Methods:A total of 107 consecutive patients with recurrent LPI were assessed between January and October 2021. Patients completed the BPII 2.0, TSK-11, PCS, and ACL-RSI. A Pearson r correlation coefficient was employed to examine relationships between the PROMs. Baseline values, as well as floor and ceiling effects and Cronbach alpha, were assessed for all PROMs.Results:All 107 patients completed the 4 PROMs. Patients included 28 men (26.2%) and 79 women (73.8%), with a mean (SD) age of 25.7 (9.8) years. The mean (SD) age at first dislocation was 14.8 (6.3) years. The TSK-11, PCS, and ACL-RSI were all statistically significantly correlated with the BPII 2.0 ( P < .01; 2-tailed), with moderate correlations ( r = -0.361-0.628) The R2 values indicated an overlap of the constructs measured by the PROMs.Conclusion:A statistically significant correlation was evident between the BPII 2.0 and the other PROMs. The BPII 2.0 does not explicitly measure kinesiophobia or pain catastrophizing; however, the significant statistical relationship of the TSK-11 and PCS to the BPII 2.0 suggests that this information is being captured and reflected.

运动恐惧症和疼痛灾难化对复发性髌股关节不稳定患者疾病特异性生活质量的影响


背景： Banff 髌股关节不稳定仪 2.0 （BPII 2.0） 是一种疾病特异性、生活质量患者报告的结果测量 （PROM），对复发性外侧髌股关节不稳定 （LPI） 患者有效可靠。生活质量包括患者功能和恢复的身体、情感和心理方面。目的： 同时验证 BPII 2.0 与运动恐惧症坦帕量表 （TSK-11） 、疼痛灾难化量表 （PCS） 和前交叉韧带-受伤后重返运动量表 （ACL-RSI） 在复发性 LPI 患者中，并评估 LPI 患者 PROMs 的基线值。研究设计： 队列研究 （诊断）;证据水平， 2.方法： 2021年1月至10月共评估了 107 例连续复发性 LPI 患者。患者完成了 BPII 2.0 、 TSK-11 、 PCS 和 ACL-RSI。采用 Pearson r 相关系数来检查 PROM 之间的关系。评估所有 PROM 的基线值以及地板和天花板效应以及 Cronbach α.结果： 所有 107 例患者都完成了 4 例 PROM。患者包括 28 名男性 （26.2%） 和 79 名女性 （73.8%），平均 （SD） 年龄为 25.7 （9.8） 岁。首次脱位的平均 （SD） 年龄为 14.8 （6.3） 岁。TSK-11 、 PCS 和 ACL-RSI 均与 BPII 2.0 （ P < .01;2 尾）呈统计学显著相关，具有中等相关性 （r = -0.361-0.628） R2 值表明 PROMs 测量的构建体重叠。结论： BPII 2.0 与其他 PROM 之间存在明显的统计学显著相关性。BPII 2.0 不明确测量运动恐惧症或疼痛灾难化;然而，TSK-11 和 PCS 与 BPII 2.0 的显著统计关系表明这些信息正在被捕获和反映。
