The purpose of this study was to provide evidence of validity for the Hip Outcome Score (HOS) as an outcome instrument in hip arthroscopy.
We mailed the short form 36 (SF-36) and HOS questionnaires, as well as questionnaires regarding self-reported current activity level (normal, nearly normal, abnormal, or severely abnormal) and self-reported surgical outcome (excellent/good or fair/poor), to 337 subjects. Medical records were used to collect surgical and demographic information. Two groups were formed for those above and below the median age. Pearson correlation coefficients were used to assess the relation between the SF-36 scores and HOS scores. One-way analysis of variance was used to determine whether HOS scores differed according to current level of function, surgical outcome, and age.
Of the subjects, 116 (34%) returned the questionnaire material. Nine of these subjects reported having surgery after August 2003 and were excluded. The data analysis was therefore performed on 107 subjects (32%). Within this group, there were 56 female patients (52%) and 51 male patients (48%), with a mean age of 42 years (median, 44.2 years; range, 14 to 79 years; SD, 14) and mean time to follow-up of 3.1 years (range, 2 to 4.6 years; SD, 0.49). The HOS activities of daily living (ADL) and sports subscales had a high correlation to the SF-36 physical function subscale (r = 0.86 and r = 0.84, respectively) and physical component summary score (r = 0.80 and r = 0.81, respectively) and a significantly (P < .005) lower correlation to the mental health subscale (r = 0.41 and r = 0.43, respectively) and mental component summary score (r = 0.17 and r = 0.18, respectively). HOS ADL and sports subscale scores were significantly different based on current activity level, surgical outcome, and age (P < .002).
This study provides evidence of validity for the HOS in a sample of subjects at a mean of 3 years after hip arthroscopy. As hypothesized, the HOS scores had a high correlation to measures of physical function and a low correlation to measures of mental health. The HOS scores were different based on subjects' reported current activity level, reported surgical outcome, and age. The results of this study support the use of the HOS ADL and sports subscales as a self-report outcome instrument for hip arthroscopy.
Level III, development of diagnostic criteria in a study of nonconsecutive patients.
本研究旨在为髋关节镜检查中使用髋关节结果评分（HOS）作为结果评估工具提供有效性证据。
我们向337名受试者邮寄了简短健康调查问卷（SF-36）、HOS问卷，以及关于自我报告的当前活动水平（正常、接近正常、异常或严重异常）和自我报告的手术结果（优秀/良好或一般/较差）的问卷。使用病历收集手术和人口统计学信息。根据年龄中位数将受试者分为两组。采用Pearson相关系数评估SF-36评分与HOS评分之间的关系。使用单因素方差分析确定HOS评分是否因当前功能水平、手术结果和年龄而有所不同。
受试者中，116名（34%）返回了问卷材料。其中9名受试者报告在2003年8月之后进行了手术，被排除在外。因此，对107名受试者（32%）进行了数据分析。在这组受试者中，有56名女性患者（52%）和51名男性患者（48%），平均年龄为42岁（中位数为44.2岁；范围为14至79岁；标准差为14），平均随访时间为3.1年（范围为2至4.6年；标准差为0.49）。HOS日常生活活动（ADL）和运动亚量表与SF-36身体功能亚量表（分别为r = 0.86和r = 0.84）以及身体成分汇总评分（分别为r = 0.80和r = 0.81）高度相关，而与心理健康亚量表（分别为r = 0.41和r = 0.43）以及心理成分汇总评分（分别为r = 0.17和r = 0.18）的相关性显著较低（P <.005）。基于当前活动水平、手术结果和年龄，HOS ADL和运动亚量表评分存在显著差异（P <.002）。
本研究为髋关节镜检查后平均3年的受试者样本中HOS的有效性提供了证据。正如所假设的，HOS评分与身体功能测量指标高度相关，与心理健康测量指标相关性较低。HOS评分因受试者报告的当前活动水平、报告的手术结果和年龄而有所不同。本研究结果支持将HOS ADL和运动亚量表用作髋关节镜检查的自我报告结果评估工具。
