Do more postoperative X-rays improve patient perception following total knee arthroplasty? A prospective randomized study.
Trial report in Journal of orthopaedic surgery and research, 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
purposeThis study aimed to evaluate the impact of two versus five postoperative X-ray protocols on patient perception following total knee arthroplasty (TKA), specifically assessing functional outcomes, quality of life, patient satisfaction and complication detection.
methodsIn this prospective randomized study, 206 patients who underwent TKA were assigned to one of two postoperative radiograph protocols. Group 1 (n = 102) received five X-rays at predefined intervals (immediately postoperative, 1 month, 3 months, 6 months, and 1 year), while Group 2 (n = 104) received only two X-rays (immediately postoperative and at 1 year). Functional outcomes were evaluated using the Knee Society Score (KSS) and Short Form-12 (SF-12). Satisfaction and complications were recorded over a 1-year follow-up period.
resultsAt the 1-year follow-up, KSS-Function scores were comparable between groups (76.07 vs. 74.32, p-value = 0.234), while KSS-Knee scores were slightly higher in Group 2 (85.44 vs. 89.3, p-value = 0.003). Regarding quality of life, SF-12 physical scores were similar (44.01 vs. 43.64, p-value = 0.628), whereas SF-12 mental scores were higher in Group 2 (56.72 vs. 58.57, p-value = 0.048). Mean satisfaction scores were comparable between groups (7.49 vs. 7.99, p = 0.08). No significant differences in complication rates were observed between groups (5 vs. 2, p-value = 0.458).
conclusionIncreasing the number of postoperative X-rays after TKA did not improve patient satisfaction or perception of recovery. Patients who received only two X-rays reported similar or slightly better functional outcomes, mental well-being, and satisfaction levels compared to those who received five. Additionally, no benefit was observed in complication detection. These findings suggest that a more limited radiographic follow-up may be sufficient, reducing costs and radiation exposure without compromising patient confidence or clinical outcomes.
