The High Activity Arthroplasty Score (HAAS) is a validated score that assesses functional outcomes after lower limb arthroplasty, with fewer ceiling effects than other scores. The aim is to translate and cross-culturally adapt the HAAS into a Chinese version (HAAS-C) and to evaluate the psychometric properties of HAAS-C in patients after primary total knee arthroplasty (TKA).
A total of 104 patients diagnosed with knee osteoarthritis who had undergone TKA at least 12 months prior were recruited. A forward and backward translation procedure was performed for developing a culturally acceptable HAAS-C. Internal consistency was assessed using Cronbach's α, and test-retest reliability was measured using the intraclass correlation coefficient (ICC) within a 10-day interval. Construct validity was assessed by examining the correlations between HAAS-C and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), EuroQoL Group's five-dimension questionnaire (EQ-5D-5L), and Oxford knee score (OKS).
HAAS-C demonstrated adequate Internal consistency reliability, as indicated by Cronbach's α coefficient of 0.75. Test-retest reliability yielded excellent results, with an ICC value of 0.98. Content validity indices were high, with a scale-level validity index of 0.9 and item-level validity indices greater than or equal to 0.8. HAAS-C showed a strong correlation with WOMAC ( = 0.69), a moderate correlation with EQ-5D-5L ( = 0.43), and OKS ( = 0.53) while exhibiting no floor or ceiling effects.
The validated HAAS-C questionnaire is a valid instrument for assessing patients undergoing TKA in mainland China.
高活动度关节成形术评分（HAAS）是一种经过验证的评分系统，用于评估下肢关节成形术后的功能结局，其天花板效应低于其他评分。目的是将HAAS翻译并进行跨文化调适，形成中文版（HAAS-C），并评估HAAS-C在初次全膝关节置换术（TKA）患者中的心理测量学特性。
共招募了104例诊断为膝关节骨关节炎且至少在12个月前接受过TKA的患者。采用正向和反向翻译程序来制定文化上可接受的HAAS-C。使用Cronbach's α评估内部一致性，在10天间隔内使用组内相关系数（ICC）测量重测信度。通过检查HAAS-C与西安大略和麦克马斯特大学骨关节炎指数（WOMAC）、欧洲生活质量五维度问卷（EQ-5D-5L）和牛津膝关节评分（OKS）之间的相关性来评估结构效度。
HAAS-C显示出足够的内部一致性信度，Cronbach's α系数为0.75。重测信度产生了优异的结果，ICC值为0.98。内容效度指数较高，量表水平效度指数为0.9，项目水平效度指数大于或等于0.8。HAAS-C与WOMAC呈强相关（= 0.69），与EQ-5D-5L呈中度相关（= 0.43），与OKS呈中度相关（= 0.53），同时未表现出地板效应或天花板效应。
经过验证的HAAS-C问卷是评估中国大陆接受TKA患者的有效工具。
