Crosscultural adaptation and validation of the simplified Chinese version of the new knee society scoring system.
Article in Annals of medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThe 2011 Knee Society Score (new-KSS) describes symptom, satisfaction, expectation, and functional activities in patients undergoing total knee arthroplasty (TKA) and is widely recognized for assessing TKA outcomes. Before using this scale in non-English-speaking populations, it must be translated and culturally adapted to suit the specific demographic.
methodsThe new-KSS was translated and culturally adapted into the new-KSS-CV following international guidelines. Item modifications were informed by the Chinese TKA PROM (CTP), a Delphi expert consensus and cognitive interviews with Chinese TKA patients, aiming to reflect local cultural and activity patterns. The adapted scale was applied in a validation study with preoperative and one-year postoperative assessments. Reliability was assessed using intraclass correlation coefficient (ICC) and Cronbach's α. Construct validity was tested by comparing the new-KSS-CV with the Chinese versions of the WOMAC and SF-12. Responsiveness was determined by calculating the standardized response means (SRM).
resultsA total of 226 patients were included, with a mean age of 64.7 ± 5.7 years; 142 (62.8%) were female. All patients completed both preoperative and one-year postoperative assessments. Ceiling effects were observed preoperatively in the expectation dimension (40.7% of patients) and postoperatively in symptom (54.4%), functional (72.1%), and standard activities (19.0%) domains. The new-KSS-CV showed good to excellent test-retest reliability (ICC: 0.88-0.97) and internal consistency (Cronbach's α: 0.74-0.85). The total score correlated significantly and moderately negatively with WOMAC (r = -0.68,
conclusionThe new-KSS-CV is a reliable, valid, responsive, and consistent outcome measurement tool that can be used to evaluate the outcome of TKA in Chinese patients.
