Impact of Weight-Bearing and Early Mobilization in Patients After Internal Fixation of Unstable Ankle Fractures: A Randomized Controlled Trial.
Article in JB & JS open access. 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
Background: Optimal postoperative management of unstable ankle fractures after internal fixation remains unclear. Traditional care uses prolonged immobilization and delayed weight-bearing (DWB), but early mobilization may accelerate recovery. This study evaluated whether early weight-bearing (EWB) and mobilization improve functional outcomes, rehabilitation progress, and complication rates after surgical fixation. Methods: This randomized controlled trial included 52 adult patients (18-65 years) with acute unilateral unstable ankle fractures treated through open reduction and internal fixation. Participants were randomly allocated into 2 groups: (1) EWB and mobilization (initiated after 2 weeks of non-weight-bearing) and (2) DWB (continuing non-weight-bearing an additional 4 weeks). The primary outcomes were time to return to work, time to full weight-bearing, and functional recovery measured by the Olerud-Molander Ankle Score (OMAS). Secondary outcomes included range of motion (ROM), physiotherapy sessions, and complication rates. Both groups followed a standardized postoperative rehabilitation program; however, the EWB group commenced protected weight-bearing and physiotherapy at 2 weeks postoperatively, whereas the DWB group remained non-weight-bearing until 6 weeks, when physiotherapy began. Results: Patients in the EWB group demonstrated a faster return to work (41.38 ± 10.20 vs. 51.88 ± 6.18 days, p < 0.001) and required fewer physiotherapy sessions (85% needing <8 sessions vs. 11.5% in the control group, p < 0.001). Functional outcomes were superior in the EWB group, with significantly higher OMAS scores from 6 weeks onward (p < 0.001). ROM improved rapidly in the intervention group, showing significant differences at 6 weeks and persisting through 12 months (p < 0.001). Despite early mobilization, complication rates, including wound complications (3.8% vs. 7.7%, p = 0.552) and fixation failure, were comparable between groups. Conclusion: EWB and mobilization after internal fixation of unstable ankle fractures enhance functional recovery, accelerate rehabilitation, and reduce the time to return to daily activities without increasing complications. However, given the modest sample size and single-center design, these findings should be interpreted cautiously, and confirmation in larger studies is needed before routine adoption. Trial Registration: This study was retrospectively registered in the Iranian Registry of Clinical Trials (IRCT20201124049484N1).
