Statistical improvement in patient-reported outcomes (PROs) does not necessarily equate to clinical benefit. Clinometric outcome thresholds have been used to provide a better insight into postoperative functional status and patient satisfaction in total hip arthroplasty (THA). This study aimed to define and evaluate patient acceptable symptomatic state (PASS) at the 10-year follow-up time point for modified Harris Hip Score (mHHS), Harris Hip Score (HHS), Hip Disability and Osteoarthritis Outcome Score - Joint Replacement (HOOS-JR), and Forgotten Joint Score (FJS).
Prospectively collected data were retrospectively reviewed for all patients who underwent primary THA between 2008 and 2015. Patients were included in the study if they had complete PROs with anchor questions at the 10-year timepoint. The PASS thresholds were then defined using the anchor-based method for mHHS, HHS, HOOS-JR, and FJS.
A total of 176 hips were included in the study, with 101 women (57.4%). The average age, body mass index, and follow-up time were 58 ± 8.2 years, 29.4 ± 5.1, and 124.9 ± 6.9 months, respectively. The areas under the curves were as follows: mHHS 0.87, HHS 0.87, HOOS-JR 0.87, and FJS 0.71, indicating acceptable to excellent discrimination for all defined thresholds. The threshold for achieving PASS at 10-year follow-up was as follows: mHHS 79.5, HHS 81.3, HOOS-JR 75.1, and FJS 76.0.
This study establishes the PASS thresholds for mHHS, HHS, HOOS-JR, and FJS at the 10-year follow-up time point following primary THA. These findings offer clinicians valuable reference points for assessing clinical success over the long term.
患者报告结局（PROs）的统计学改善并不一定等同于临床获益。临床测量结局阈值已被用于更深入了解全髋关节置换术（THA）后的功能状态和患者满意度。本研究旨在确定并评估改良Harris髋关节评分（mHHS）、Harris髋关节评分（HHS）、髋关节残疾与骨关节炎结局评分 - 关节置换（HOOS-JR）和遗忘关节评分（FJS）在10年随访时间点的患者可接受症状状态（PASS）。
对2008年至2015年间接受初次THA的所有患者的前瞻性收集数据进行回顾性分析。如果患者在10年时间点有完整的带有锚定问题的PROs，则纳入本研究。然后使用基于锚定的方法为mHHS、HHS、HOOS-JR和FJS定义PASS阈值。
本研究共纳入176例髋关节，其中女性101例（57.4%）。平均年龄、体重指数和随访时间分别为58±8.2岁、29.4±5.1和124.9±6.9个月。曲线下面积如下：mHHS为0.87，HHS为0.87，HOOS-JR为0.87，FJS为0.71，表明所有定义的阈值具有可接受至优秀的区分度。10年随访时达到PASS的阈值如下：mHHS为79.5，HHS为81.3，HOOS-JR为75.1，FJS为76.0。
本研究确定了初次THA后10年随访时间点mHHS、HHS、HOOS-JR和FJS的PASS阈值。这些发现为临床医生评估长期临床成功提供了有价值的参考点。
