HOT TOPIC: ACL Graft Size Matters in Younger Patients


We hypothesized that decreased graft size and younger patient age are predictors of early revision following primary ACL reconstruction with hamstring autograft. In a recent study at our institution, 256 of 338 consecutive patients (75.7%) were evaluated at an average of 14 months following surgery. The overall revision rate was 7%. Age younger than 20 years at the time of reconstruction (OR = 18.97; 95% CI = 2.43–147.06; = 0.005) and decreased graft size (OR = 2.20; 95% CI = 1.00–4.85; = 0.05) were associated with significantly increased risk of revision. Most revisions (16 of 18) were performed in patients younger than 20 years of age, with grafts 8 mm in diameter or less. The revision rate in this population was 16.4% (16 of 97 patients). Graft size may be an important variable in predicting the outcome of primary ACL reconstructions performed with hamstring autograft.
