Two-Year Outcomes of ACL Reconstruction With Osteochondral Allograft Transplantation Versus Isolated ACL Reconstruction: A Matched Cohort Study.
Article in Orthopaedic journal of sports medicine, 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
Background: Osteochondral allograft transplantation (OCA) has been established as a viable restorative chondral procedure, although few studies have examined its effectiveness in the setting of anterior cruciate ligament (ACL) reconstruction. Purpose: To compare self-reported function and return-to-sport rates after ACL reconstruction with OCA to those of matched controls undergoing isolated ACL reconstruction. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective matched cohort study was conducted utilizing a single-surgeon database of patients undergoing ACL reconstruction between 2016 and 2021. Included patients were 15 to 70 years of age, underwent ACL reconstruction with OCA, and desired to return to sport. Patients were age and sex matched to a cohort of patients who underwent isolated ACL reconstruction. Baseline characteristics were collected along with preinjury Marx score and surgical details. Outcomes at time of return to sport included self-reported function, time to return to sport, range of motion, and single-leg squat and hopping performance. Two-year outcomes included Single Assessment Numeric Evaluation (SANE) scores, return-to-sport rates, and reinjury rates. Between-group differences were analyzed utilizing chi-square analyses and 1-way analysis of variance with an a priori α value of .05. Results: A total of 43 patients who underwent ACL reconstruction with OCA were identified and matched to 43 patients who underwent isolated ACL reconstruction. Patients in the ACL reconstruction with OCA group reported lower preinjury Marx scores (3.9 ± 5.7 vs 9.6 ± 5.9; Conclusion: Patients undergoing ACL reconstruction with OCA demonstrate similar self-reported function and return-to-sport rates, along with a delayed time to return to sport, to those undergoing isolated ACL reconstruction. A majority (83.7%) of patients undergoing ACL reconstruction with OCA can return to level 1 to 3 sports with low graft failure rates.
