The High\u2010Activity Arthroplasty Score (HAAS) is a self\u2010administered instrument focussing on the wider range of functional abilities of more active patients. The HAAS was developed in English and is not available in German yet. This study aims to translate, cross\u2010cultural adapt and assess the psychometric properties of the German HAAS in patients 12\u00a0months after primary TKA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>After forward and backward translation, we examined the final version regarding its psychometric properties in patients 12\u00a0months after primary TKA. The HAAS was sent out to 70 patients together with routine questionnaires comprising the Knee injury and Osteoarthritis Outcome Score (KOOS), the Forgotten Joint Score (FJS\u201012), the EuroQol (EQ\u20105D\u20103L) and 2\u00a0numerical pain rating scales. Acceptability, reliability, responsiveness, content and construct validity as well as floor and ceiling effects were evaluated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Fifty\u2010two patients were recruited. The HAAS was well accepted with a mean time to completion of 2.4\u00a0min. Cronbach\u2019s alpha for internal consistency was 0.749, test\u2013retest reliability was excellent with an Intraclass Correlation Coefficient (ICC) of 0.961. The smallest detectable change was 1.5. Good content validity was confirmed. A strong correlation was found between the HAAS and KOOS sport (<jats:italic>r<\/jats:italic>\u2009=\u20090.661) and a medium correlation for all other KOOS subscales (<jats:italic>r<\/jats:italic>\u2009=\u20090.324 to 0.453), the FJS\u201012 (<jats:italic>r<\/jats:italic>\u2009=\u20090.425), the EQ\u20105D\u20103L (<jats:italic>r<\/jats:italic>\u2009=\u20090.427) and pain (<jats:italic>r<\/jats:italic>\u2009=\u2009\u2212 0.439 to \u2212 0.308). The HAAS showed no floor and ceiling effects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The German version of the HAAS provides good validity and reliability.
