Due to a lack of a validated Dutch version of the Hip Outcome Score (HOS) considering functional outcome after hip arthroscopy for femoroacetabular impingement syndrome, we validated the Dutch version of the HOS (HOS-NL) in patients with femoroacetabular impingement syndrome for reliability, internal consistency, construct- and content validity. Furthermore, the smallest detectable change (SDC) and minimal clinically important difference (MCID) were determined. All consecutive patients scheduled for an arthroscopic procedure for FAIS were selected. Five questionnaires covering groin and hip pain were filled in at three moments in time (two pre-operatively with a maximum two-week interval and 6 months postoperatively). Main endpoints were reliability (test re-test, SDC), internal consistency (Cronbach alpha), construct validity (construct validity was considered sufficient if a least 75% of a-priori made hypotheses were confirmed), content validity (floor and ceiling effects) and responsiveness (MCID). The intraclass correlation coefficient (ICC) was 0.86 for the HOS ADL-NL and 0.81 for the HOS Sports-NL. SDC for the HOS ADL-NL was 21 and for the HOS Sports-NL 29 Cronbach alpha score was 0.882 for HOS ADL-NL and 0.792 for HOS Sports-NL. Construct validity was considered sufficient since 91% of the hypotheses were confirmed. No floor effects were determined. A small ceiling effect was determined for the HOS AD-NL postoperatively. The MCID for HOS ADL-NL and HOS Sports-NL were 14 and 11.0, respectively. The HOS-NL is a reliable and valid patient reported outcome measure for measuring physical function and outcome in active and young patients with femoroacetabular impingement syndrome.

荷兰版髋关节结果评分的验证；股骨髋臼撞击综合征患者的有效性、可靠性和反应性


由于缺乏考虑股骨髋臼撞击综合征髋关节镜术后功能结果的经过验证的荷兰版髋关节结果评分 (HOS)，我们验证了荷兰版 HOS (HOS-NL) 在股骨髋臼撞击综合征患者中的可靠性，内部一致性、结构有效性和内容有效性。此外，还确定了最小可检测变化（SDC）和最小临床重要差异（MCID）。选择所有计划进行 FAIS 关节镜手术的连续患者。在三个时间点填写五份涵盖腹股沟和臀部疼痛的调查问卷（其中两份在术前，最长间隔两周，在术后六个月）。主要终点是可靠性（重测，SDC）、内部一致性（Cronbach alpha）、结构效度（如果至少 75% 的先验假设得到证实，则结构效度被认为是足够的）、内容效度（下限和上限效应） ）和响应能力（MCID）。 HOS ADL-NL 的组内相关系数 (ICC) 为 0.86，HOS Sports-NL 的组内相关系数 (ICC) 为 0.81。 HOS ADL-NL 的 SDC 为 21，HOS Sports-NL 29 HOS ADL-NL 的 Cronbach alpha 得分为 0.882，HOS Sports-NL 为 0.792。结构效度被认为是足够的，因为 91% 的假设得到了证实。未确定地板效应。术后确定 HOS AD-NL 的天花板效应较小。 HOS ADL-NL 和 HOS Sports-NL 的 MCID 分别为 14 和 11.0。 HOS-NL 是一种可靠且有效的患者报告结果测量方法，用于测量患有股骨髋臼撞击综合征的活跃和年轻患者的身体功能和结果。
