The HOOS and KOOS scoring questionnaires comprise respectively 40 and 42 items; a shorter 12-item version was recently developed, but remains to be validated in a French-speaking population. We therefore conducted a prospective study: 1) to determine whether the new 12-item versions in French are equivalent to the longer HOOS and KOOS versions, and 2) to validate the French-language HOOS-12 and KOOS-12 patient-reported outcome measures in a population of primary total hip and knee arthroplasty: validity, reliability, and responsiveness.
The change in language in a score already validated in its long version does not alter its properties in the short version.
One hundred patients (59 males, 41 females) undergoing primary total hip arthroplasty and 100 patients (43 males, 57 females) undergoing primary total knee arthroplasty were prospectively included. They filled out the original HOOS or KOOS questionnaires, their simplified versions (PS: Physical function Short form; JR: Joint Replacement) and the short HOOS-12 and KOOS-12 versions, and also the Oxford-12 score assessing the affected joint, preoperatively, then at 6-12 months.
The 100% response rate confirmed ease of use. There were no redundant items. There were strong correlations between the 12-item and longer versions (>0.9). The HOOS-12 and KOOS-12 scores were reliable and valid: 1) there were no ceiling or floor effects for pre- or postoperative KOOS-12 scores, although a ceiling effect was found for HOOS-12 postoperatively (20% of patients having maximum scores of 100); 2) internal consistency was confirmed, with Cronbach alpha>0.8; 3) external consistency between Oxford-12 and HOOS-12/KOOS-12 was excellent, with Pearson correlation coefficient>0.8. Sensitivity to pre-/postoperative change was confirmed, with effect size>0.8.
The present study confirmed the usefulness of this new 12-item form for HOOS and KOOS. Properties were identical between the French- and English-language versions, authorising everyday use of these simpler versions.

HOOS 和 KOOS 评分问卷分别包含 40 项和 42 项条目；最近开发了一种更短的 12 项版本，但仍需要在法语人群中进行验证。因此，我们进行了一项前瞻性研究：1）确定法语新的 12 项版本是否与较长的 HOOS 和 KOOS 版本等效，2）验证法语版 HOOS-12 和 KOOS-12 患者报告的结果测量在原发性全髋关节和膝关节置换术人群中的有效性、可靠性和反应性。
在已经通过长版本验证的评分中改变语言不会改变短版本的性质。
前瞻性纳入 100 例（59 例男性，41 例女性）接受初次全髋关节置换术和 100 例（43 例男性，57 例女性）接受初次全膝关节置换术的患者。他们填写了原始的 HOOS 或 KOOS 问卷、简化版本（PS：物理功能简表；JR：关节置换）以及简短的 HOOS-12 和 KOOS-12 版本，以及术前、术后 6-12 个月评估受影响关节的牛津-12 评分。
100%的回复率证实了易用性。没有冗余项目。12 项和较长版本之间存在很强的相关性（>0.9）。HOOS-12 和 KOOS-12 评分可靠且有效：1）KOOS-12 的术前和术后评分均无天花板或地板效应，尽管术后 HOOS-12 评分存在天花板效应（20%的患者得分为 100 分）；2）内部一致性得到证实，Cronbach alpha>0.8；3）牛津-12 与 HOOS-12/KOOS-12 之间的外部一致性很好，Pearson 相关系数>0.8。证实了术前/术后变化的敏感性，效应大小>0.8。
本研究证实了这种新的 12 项 HOOS 和 KOOS 形式的有用性。法语和英语版本之间的性质相同，授权日常使用这些更简单的版本。
