Patient-reported outcomes after total knee replacement: Questionnaire and functional assessment study.
Article in Bioinformation, 2026. 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
Recent studies indicate that although many patients are satisfied with their surgical results after total knee replacement (TKR), there is still concern regarding ongoing levels of pain, limited mobility and differences in the level of satisfaction among patients. Therefore, it is of interest to prospectively evaluate patient-reported outcomes and functional recovery in TKR patients following the completion of at least 6 months post-operative recovery through the application of KOOS, SF-36 and time up, go and 6-minute walk tests. In this study, KOOS Pain scores increased from an average of 45.6 points before surgery to an average of 82.1 points after surgery, while SF-36 physical functioning scores increased from an average of 41.2 points preoperatively to an average of 80.5 points at follow-up (p<0.001). Additionally, functional mobility improved significantly through decreased times on the timed up and go test from 18.4 seconds preoperatively to 10.2 seconds postoperatively (p<0.001) and increased distances walked during the 6-minute walk test from 230.7 meters to 360.8 meters (p<0.001). Furthermore, TKR has led to significant increases in patient satisfaction, functional independence and overall quality of life for TKR patients.
