The German version of the High-Activity Arthroplasty Score is valid and reliable for patients after total knee arthroplasty.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe indications for a total knee arthroplasty (TKA) broadened to younger and more active patients. The High-Activity Arthroplasty Score (HAAS) is a self-administered 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-cultural adapt and assess the psychometric properties of the German HAAS in patients 12 months after primary TKA.
methodsAfter forward and backward translation, we examined the final version regarding its psychometric properties in patients 12 months 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-12), the EuroQol (EQ-5D-3L) and 2 numerical pain rating scales. Acceptability, reliability, responsiveness, content and construct validity as well as floor and ceiling effects were evaluated.
resultsFifty-two patients were recruited. The HAAS was well accepted with a mean time to completion of 2.4 min. Cronbach's alpha for internal consistency was 0.749, test-retest 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 (r = 0.661) and a medium correlation for all other KOOS subscales (r = 0.324 to 0.453), the FJS-12 (r = 0.425), the EQ-5D-3L (r = 0.427) and pain (r = - 0.439 to - 0.308). The HAAS showed no floor and ceiling effects.
conclusionsThe German version of the HAAS provides good validity and reliability. It can be easily self-administered and is recommended to capture high-intensity activities in patients after TKA. LEVEL OF EVIDENCE: Diagnostic study, Level I.
