Outcomes of acute versus delayed multi-ligament knee injury reconstruction: A retrospective analysis with mean 3.6-year follow-up.
Article in European journal of orthopaedic surgery & traumatology : orthopedie traumatologie, 2025. 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 AND
objectiveMulti-ligament knee injuries (MLKIs) are debilitating injuries, often managed with surgical reconstruction. Our purpose was to determine whether acute or delayed reconstruction led to better functional and patient-reported outcomes. MATERIALS AND
methodsAn institutional dataset was queried for patients who underwent MLKI reconstruction from 2012 to 2019 and completed postoperative functional and patient-reported outcome surveys with minimum 2-year follow-up. Exclusion criteria included single ligament reconstruction, revision surgery, and periarticular tumors. Patient-reported outcomes measurement system (PROMIS) and multi-ligament quality of life (ML-QoL) outcomes were compared between patients who underwent acute (< 2 weeks) and delayed (> 2 weeks) reconstruction.
resultsThirty-three patients were included for analysis (16 acute, 17 delayed): mean follow-up 3.6 years, mean BMI 29.8 ± 5.9, mean age 37.7 ± 13.5, sex: 19(58%) females, 14(42%) males. At final follow-up, there was no statistical difference between groups in most PROMIS scores, including Lysholm knee score (63 vs. 72, p = 0.13), pain (53 vs. 47, p = 0.11), or mobility (45 vs. 49, p = 0.18). Patients who underwent delayed reconstruction demonstrated significantly higher physical function scores (46 vs. 53, p = 0.05). There was no statistical difference in majority of ML-QoL scores, including physical impairments (42 vs. 29, p = 0.09), emotional impairments (45 vs. 30, p = 0.12), and societal involvement (38 vs. 24, p = 0.09). Patients who underwent acute reconstruction reported statistically greater activity limitations than delayed reconstruction (36 vs. 21, p = 0.02). There were no significant differences in complication rates between groups.
conclusionDelayed MLKI reconstruction had comparable results to acute reconstruction for PROMIS and ML-QoL outcomes, and had greater physical function and lower activity limitation postoperatively. These data demonstrate that delayed reconstruction may be an appropriate management option for MLKI reconstruction. LEVEL OF EVIDENCE: Level III, Retrospective Cohort study.
