Retrospective cohort study evaluates revision ACLR risk related to hamstring graft size and body size in football players, suggesting tailored approaches.
Key Points
This research aims to assess the relationship between hamstring autograft diameter and the risk of revision ACLR, especially concerning sex and height variations.
Nationwide registry-linked cohort assembled from the Swedish Knee Ligament Registry and the Swedish Football Association.
9,448 football players undergoing primary ACLR with hamstring autograft between 2014 and 2023 were included.
Cox models were utilized to estimate adjusted hazard ratios for revision, stratified by sex and height.
Among players, 771 revision ACLR occurred (8.2% overall); revision risk decreased with increasing graft diameter.
Tall male players (176-184 cm) had a 2.27-fold higher risk for ≤7.5 mm grafts compared to ≥9.0 mm (HR 2.27, 95% CI 1.30-3.94).
No significant risk differences were found in shorter men and women of all heights.
