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).Methods: 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).Results: 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 (r = 0.69), a moderate correlation with EQ-5D-5L (r = 0.43), and OKS (r = 0.53) while exhibiting no floor or ceiling effects.Conclusion: The validated HAAS-C questionnaire is a valid instrument for assessing patients undergoing TKA in mainland China.Keywords: high activity arthroplasty score, total knee arthroplasty, Chinese validation, reliability, validity
