The purpose of this study is to translate and cross-culturally adapt the HAAS instrument into Turkish and investigate its psychometric properties. For cross-cultural adaptation, two bi-lingual translators used the back-translation procedure. Within a 5-to-7-day period after the first assessment, the participants will complete the Turkish version of HAAS to evaluate test-retest reliability. Cronbach's alpha (α) will use to assess internal consistency. The correlations with the Turkish version of the KOOS, SF-36 and FJS-12 will determine to check the validity.
The objectives of this study were the translation, cross-cultural adaptation, and assessment of the psychometric properties of the Turkish High-Activity Arthroplasty Score (HAAS) in patients with primary TKA.
