Popis: Background: Bone–patellar tendon–bone (BPTB) autografts are widely considered the standard for anterior cruciate ligament reconstruction (ACLR). Purpose/Hypothesis: The aims of this study were to compare the clinical outcomes after ACLR with gold standard BPTB autografts versus combined ACLR + anterolateral ligament reconstruction (ALLR) with hamstring tendon (HT) autografts at medium-term follow-up in a large series of propensity-matched patients. The hypothesis was that combined ACLR + ALLR with HT autografts would result in lower graft rupture rates and non–graft rupture-related reoperation rates. Study Design: Cohort study; Level of evidence, 3. Methods: Patients undergoing combined ACLR + ALLR using HT autografts between January 2003 and December 2019 were propensity matched in a 1:1 ratio to patients undergoing isolated ACLR using BPTB autografts. At the end of the study period, graft ruptures, contralateral knee injuries, and any other reoperations or complications after the index procedure were identified by a search of a prospective database and a review of medical records. Results: A total of 1009 matched pairs were included. The mean duration of follow-up was 101.3 ± 59.9 months. Patients in the isolated group were >3-fold more likely to have graft failure than those in the combined group (hazard ratio, 3.554 [95% CI, 1.744-7.243]; P = .0005). Patients aged 30 years (hazard ratio, 5.650 [95% CI, 1.834-17.241]; P = .0002). Additionally, there was a significantly higher reoperation rate after isolated ACLR than after combined ACLR + ALLR (20.5% vs 8.9%, respectively; P < .0001). The overall rate of subsequent contralateral ruptures was 9.1% after index surgery (isolated: 10.2%; combined: 8.0%; P = .0934), indicating that the risk profiles for both groups were similar. Conclusion: Patients who underwent isolated ACLR with BPTB autografts experienced significantly worse graft survivorship and overall reoperation-free survivorship compared with those who underwent combined ACLR + ALLR with HT autografts. The risk of graft ruptures was >3-fold higher in patients who underwent isolated ACLR using BPTB autografts.
