Abstract Purpose To compare subjective knee function and revision rates at the 5‐year follow‐up in young females (14–25 years) undergoing primary anterior cruciate ligament reconstruction (ACLR) with either hamstring tendon (HT) or bone–patellar tendon–bone (BPTB) autografts in a nationwide registry‐based cohort. Methods Data were extracted from the Swedish knee ligament registry (SKLR). Female patients aged 14–25 years who underwent primary ACLR using either HT or BPTB autografts between 2005 and 2018 were identified. Patient‐reported knee function was assessed using the Knee injury and Osteoarthritis Outcome Score (KOOS) and the average score for four of the five KOOS subscales (KOOS 4 ), including Pain, Symptoms, Sport p < 0.001), 2‐year (63.9 ± 26.8 vs. 59.1 ± 25.5; p = 0.004) and 5‐year follow‐up (65.3 ± 27.5 vs. 60.6 ± 25.7; p = 0.015), with no significant differences in the other KOOS subscales. KOOS 4 scores were higher in the HT group at 1‐year (71.0 ± 18.2 vs. 68.3 ± 17.4; p = 0.015), but no between‐group differences were observed at 2‐ or 5‐year follow‐up. The proportion of patients achieving a PASS on KOOS 4 at 1‐year was significantly higher in the HT group compared with the BPTB group (39.5% vs. 33.0%; p = 0.028); however, no differences were observed at the 2‐ or 5‐year follow‐up. No differences were observed between the groups in TF outcomes at 1‐, 2‐ or 5‐year follow‐up. The 5‐year revision rates were 7.0% for HT and 7.5% for BPTB groups, with no significant difference in the hazard of revision ACLR between the groups (hazard ratio = 1.05, 95% confidence interval = 0.75–1.49; p = n.s.). Conclusion Similar 5‐year revision rates were observed between HT and BPTB autografts in young females. HT autografts were associated with higher subjective knee function scores than BPTB autografts, although the clinical relevance of this difference is uncertain. Level of Evidence Level III.
