Primary ACL repair in a selected patient cohort: A prospective single cohort study.
Article in Journal of orthopaedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Anterior cruciate ligament (ACL) tears are common knee injuries, particularly in physically active individuals. While ACL reconstruction (ACL-R) is the standard treatment, it has notable limitations. Recent interest in primary ACL repair offers a potential alternative, especially for specific tear types and patient demographics. Purpose: To evaluate the outcomes of primary ACL repair in a selected patient cohort with strict inclusion and exclusion criteria, focusing on the survival of the procedure, functional outcomes, and factors influencing success rates. Methods: This prospective single cohort study included 61 patients who underwent primary ACL repair between June 2016 and June 2022. Patients were 50 years or younger, with recent ACL injuries and no previous knee surgeries or multiligament injuries. The primary outcomes were the survival of the repair beyond two years, measured by revision rates, and functional outcomes assessed using the Lysholm knee score, Tegner activity scale, and Lachmeter stability measurements. Results: Fifty-four patients completed a minimum follow-up of three years (average 49.6 months). The overall success rate was 82.2 %, with Sherman type 1 tears showing significantly fewer failures compared to type 2 (4.3 % vs. 31.8 %). The mean Lysholm score for successful repairs was 96, and the Tegner score dropped from a pre-injury average of 6 to 5. Adolescents had the highest failure rate (50 %), while other age groups showed better outcomes. The mean side-to-side difference in stability was 1.4 mm, favoring the control side. Conclusion: Primary ACL repair is a viable option for selected patients, particularly those with Sherman type 1 tears. While age and tear type significantly affect outcomes, the procedure shows promising results with high functional scores in successful repairs. Further research with larger cohorts and extended follow-ups is necessary to validate these findings and refine patient selection criteria. Primary ACL repair offers a less invasive alternative to ACL reconstruction, with potential for comparable outcome.
