Preoperative education on realistic expectations improves the satisfaction of patients with central sensitization after total knee arthroplasty: a randomized-controlled trial.

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 aim of this study was to investigate whether an additional module on realistic expectations following total knee arthroplasty (TKA) would lead to a higher proportion of satisfied patients compared to existing preoperative education.
methodsThis was a single-center, randomized-controlled trial. A total of 172 patients who were scheduled for TKA between September 2020 and October 2021 were enrolled. Patients were randomized to receive either only standard preoperative education, or an additional module on realistic expectations following TKA. The primary outcome was patient satisfaction. Secondary outcomes were Short Form-36, Western Ontario and McMaster Universities Osteoarthritis Index, crepitus score, and range of motion. Subgroup analysis was performed based on central sensitization inventory (CSI) score stratification. Assessment was performed at the 3-month, 6-month, and > 1-year follow-up.
resultsAt more than 1 year, 65/78 (83.3%) patients in the intervention group and 52/80 (65.0%) patients in the control group were satisfied (P = 0.03). The mean satisfaction score was measured as 4.2 ± 0.9 in the intervention and 3.9 ± 0.9 in the control at > 1 year (P = 0.01). There were significant differences in Short Form-36 physical and mental component summary scores and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and stiffness scores at 6 months (P = 0.02, P = 0.02, P = 0.04, P = 0.04). The frequency of satisfaction and mean satisfaction score in the top 25 percentile CSI group were 15/16 (93.8%) and 4.6 ± 0.6 in those who received intervention and 12/19 (63.2%) and 3.8 ± 0.8 in those who did not (P = 0.01, P = 0.01).
conclusionsThorough preoperative education on realistic expectations following TKA showed effects on WOMAC pain and satisfaction at > 1 year after surgery. It was more prominent in the group with a higher CSI score at > 1-year follow-up. LEVEL OF EVIDENCE: Level I.
