Brief Summary

Background: Anterior cruciate ligament (ACL) injury is one of the most common orthopedic injuries worldwide. Currently, the use of the bone patellar tendon bone graft (BPTB) technique is considered the gold standard. The use of the quadriceps tendon graft (QT) has gained greater interest in recent years, this because with an adequate technique it is possible to obtain a biomechanically superior graft with fewer adverse events. The objective of this study is to compare the objective and subjective clinical results, as well as the presence or not of adverse events in ACL reconstruction with these 2 types of grafts in the medium term. Materials and methods: Controlled, longitudinal, prospective, randomized, double-blind clinical trial that will include patients of both sexes, between 15 and 55 years of age, with primary ACL injury who attend the outpatient clinic of the Sports Orthopedics Service. INRLGII arthroscopy between October 2023 and October 2025, prior informed consent. Graft selection will be done randomly 1:1 between bone-tendon-bone (BPTB) graft Vs. quadriceps tendon graft (QT) for ACL reconstruction surgery. The clinical evaluation of the patients Will be done by 2 blinded evaluators, through the objective measurement of KT-1000 and the use of subjective clinical knee scales, both preoperatively and at 3-6-12 and 24 months. The presence or absence of adverse events or complications will be documented during a minimum of 2 years of follow-up. Parametric and non-parametric statistical tests will be used depending on whether the distribution is normal or not, for dependent and independent groups, using the SPSS version 25 statistical program.

Masking Details
The selection of the graft to be used will be carried out randomly with a box with a closed envelope, which contains the same number of envelopes with one or another type of graft, and the resulting option will be the way in which the type of graft is assigned. graft, which will not be disclosed to the patient during the period of the study. Subjective and objective clinical evaluations with KT-1000 will be carried out preoperatively and postoperatively at 3, 6, 12 and 24 months by 2 evaluators who will be blinded to the type of graft used in each patient, for which the anterior part of his knee will be covered with a 20cm long "micropore" band, so that the type of graft cannot be identified by the evaluator based on the area of the knee and surgical scar.
