Comparison of Results in ACL Reconstruction in Women under 30 Years Old at a Minimum of 2 Years’ Follow-Up between a Bone–Tendon–Bone (BTB) Technique with the Patellar Tendon and a Hamstring Technique Combined with Anterolateral Ligament Reconstructi

<b>Background</b>: Anterior cruciate ligament (ACL) rupture is a frequent injury among athletes, particularly women. Various techniques have shown effectiveness, but their impact on laxity and clinical outcomes varies. This study aims to compare the rupture rates of patellar tendon (PT) reconstruction versus hamstring reconstruction (HR) combined with anterolateral ligament reconstruction (ALLR) in young women. The secondary objectives include comparing functional ACL-RSI and subjective IKDC scores, as well as the Tegner scale, between these two groups. The hypothesis is that adding ALLR to HR will result in rupture rates and functional scores similar to those of PT reconstruction. <b>Methods</b>: Between 2015 and 2019, 96 patients were treated at two facilities, with 70 having an average follow-up of 44 ± 14.5 months: 35 underwent PT reconstruction, and 35 had HR combined with ALLR. Patients were re-evaluated remotely after at least 2 years using a standardised questionnaire and assessing subjective IKDC, ACL-RSI, and Tegner scores. <b>Results</b>: Rupture rates were 5.7% in both groups. The mean subjective IKDC score was 81% for the HR + ALLR group versus 80.8% for the PT group (<i>p</i> = 0.09). The mean ACL-RSI score was 66% for HR + ALLR versus 68% for PT (<i>p</i> = 0.78). The HR + ALLR group lost an average of 0.4 points on the Tegner scale postoperatively, while the PT group lost an average of 0.77 points (<i>p</i> = 0.09). <b>Conclusions</b>: Hamstring surgery combined with anterolateral surgery provides subjective results, as assessed by patients using subjective scales and questionnaires, that are as good as those obtained with PT surgery in young women. Notwithstanding, the results are not corroborated by clinical or radiological examination.
