The purpose of this study is to compare the rate of reoperation after index hip arthroscopy for symptomatic femoroacetabular impingement in patients with, and without, at least one self-reported allergy. Data were collected prospectively in 1468 patients whose records were retrospectively reviewed. After the application of inclusion and exclusion criteria, two cohorts were formed: (i) a study cohort (n = 261) composed of patients with a self-reported allergy and (ii) a control cohort. (n = 666). The allergy cohort had a significantly larger [P < 0.001] reoperation rate (24.1% [63/261]) compared to the control cohort (9.6% [64/66]). Univariate analysis (UVA) and multivariate analysis (MVA) were then performed to better understand the implications of allergy status on the arthroscopic outcome. On UVA the presence of an allergy increased the odds of reoperation after index hip arthroscopy by 2.99 [OR (95% CI): 2.99 (2.04, 4.39); P < 0.001] and for each additional allergy a patient reported, their odds of subsequent surgery increased by 1.27 per allergy [OR (95% CI): 1.27 (1.15, 1.39); P < 0.001]. However, on the MVA, allergy status was not an independent risk factor for reoperation. These findings suggest that allergy status is associated with a higher reoperation rate, however, allergy status alone cannot prognosticate the risk of subsequent surgery. Therefore, allergy status and its association with future surgery after hip arthroscopy should be considered in the context of multiple patient-specific factors that influence the surgical outcome. An understanding of this association enables patient-centered care and will strengthen the physician–patient relationship.

自我报告过敏对髋关节镜术后再次手术的预测价值

本研究的目的是比较有和没有至少一种自我报告过敏的患者在指数髋关节镜检查后对有症状的股骨髋臼撞击的再手术率。前瞻性地收集了 1468 名患者的数据，这些患者的记录进行了回顾性审查。在应用纳入和排除标准后，形成了两个队列：（i）由自我报告过敏的患者组成的研究队列（n = 261）和（ii）对照组。（n = 666）。过敏队列具有显着更大的 [P < 0.001] 再手术率 (24.1% [63/261]) 与对照组 (9.6% [64/66]) 相比。然后进行单变量分析 (UVA) 和多变量分析 (MVA) 以更好地了解过敏状态对关节镜结果的影响。在 UVA 上，过敏的存在使髋关节镜检查后再次手术的几率增加了 2.99 [OR (95% CI)：2.99 (2.04, 4.39)；P＜0.001] 并且对于患者报告的每额外过敏，他们随后手术的几率增加 1.27 每种过敏 [OR (95% CI): 1.27 (1.15, 1.39); P＜0.001]。然而，在 MVA 上，过敏状态并不是再次手术的独立危险因素。这些研究结果表明，过敏状态与较高的再手术率相关，但是，仅过敏状态不能预测后续手术的风险。因此，过敏状态及其与髋关节镜检查后未来手术的关系应在影响手术结果的多种患者特定因素的背景下考虑。
