Fifteen-Year Radiographic Follow-up Comparison of Early Versus Delayed ACL Reconstruction: A Retrospective Review of a Previous Prospective Randomized Clinical Trial.
Article in Orthopaedic journal of sports medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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: Posttraumatic osteoarthritis (PTOA) after anterior cruciate ligament injury and reconstruction (ACLR) is a prevalent cause of long-term disability. Few studies have compared the effect of ACLR timing on the development of PTOA. Purpose/Hypothesis: The purpose of this study was to compare the rate of PTOA at a long-term follow-up between patients who underwent early ACLR (<21 days after injury) versus delayed ACLR (>6 weeks after injury). The authors hypothesized that patients who underwent early ACLR would have lower rates of PTOA compared with the delayed ACLR cohort. Study Design: Cohort study; Level of evidence, 2. Methods: The authors contacted patients from a previous prospective randomized controlled trial who were randomized to undergo either early (<21 days) or delayed (>6 weeks) ACLR with hamstring tendon autografts. Weightbearing radiographs were obtained at a minimum 15-year follow-up, and radiographic PTOA was evaluated using the Kellgren-Lawrence (K-L) classification system. The prevalence of pathologies was compared between the early and delayed groups using appropriate testing, and logistic regression was used to evaluate for associations with failure-a K-L grade of ≥2 or conversion to total knee arthroplasty (TKA). Results: At a mean follow-up of 15.6 years, radiographs were obtained for 58 (28 early, 30 delayed) of the original 69 (84.1%) patients. High rates of PTOA (K-L grade ≥2) were observed in the early (82.1%) and delayed (86.7%) cohorts ( Conclusion: In this study, >80% of patients who underwent ACLR with hamstring tendon autografts had radiographic evidence of PTOA at a mean 15.6-year follow-up, with no difference in the prevalence or severity of PTOA between the early and delayed groups. In addition, 11% of patients had converted to TKA by the time of the final follow-up, and the conversion rate did not differ according to the timing of ACLR.
