A simple, subjective, knee self-evaluation using a single question can be used for a quick assessment of patients undergoing knee surgery.

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 use of patient-reported outcome measures (PROMS) is the cornerstone of clinical research for surgical disciplines, but the use in daily routine can be challenging. One of the most widespread PROMS in knee surgery is the International Knee Documentation Committee (IKDC) questionnaire. The purpose of the present study was to investigate the potential correlation of the IKDC score with a patient's subjective assessment of the knee using a single question. We hypothesized a correlation between the IKDC score and single question score.
methodsA prospective, single center study in a comprehensive knee outpatient clinic was performed. Patients willing to participate, presenting in the clinic for the first time were asked to complete the IKDC questionnaire and to answer the question: "How does your knee know compare to when you were 16 years old, in percentage?" Pearson correlation coefficient and linear regression were used to analyze the IKDC score and the single-question percentage.
resultsAfter application of inclusion and exclusion criteria, 310 patients were included. The mean age of the participants was 43.3 ± 9.6 years, and 45.2% of the patients were female. Mean IKDC score was 41.11 ± 13.13, compared to the mean score of the single-question 40.90 ± 22.7 (p = 0.887). The correlation between the IKDC score and the single-question was significant (p < 0.001), however, the person coefficient was 0.460, indicating moderate correlation. The linear regression analysis was also statistically significant (p < 0.001), but with a model fitness of r
conclusionIKDC score and a simple, subjective, knee self-evaluation using a single question demonstrate moderate correlation. The single question can be used for better understanding of discrepancy between the objective score and the patients' subjective perception of knee function or as a fast, single question proxy score.
