Single Bundle Reconstruction
Subjects will undergo single bundle acl reconstruction
Single bundle anterior cruciate ligament reconstruction
The surgical technique includes ACL reconstruction with graft of two autologous tendons - the semitendinous and gracilis - fixed in one tibial tunnel and one femoral tunnel. Once the graft is obtained, the arthroscopy-assisted ACL reconstruction is performed using anterolateral, anteromedial and accessory anteromedial portals. The first tunnel to be built is femoral tunnel, through a Smith \& Nephew femoral guide inserted into the anteromedial portal in the 10:30 h position for the right knee and 1:30 h position for the left knee, with the knee at 120° of flexion. The next tunnel is tibial tunnel. The tunnel has its point of entry anterior to the fibers of the superficial medial collateral ligament, and the tibial guide must be adjusted at 45 degrees. The new ligament is fixed onto the tibia and femur with a biodegradable interference screw.
Double bundle reconstruction
Subjects will undergo double bundle acl reconstruction
Double bundle anterior cruciate ligament reconstruction
The ACL reconstruction is performed with graft of two autologous tendons -the semitendinous and gracilis- fixed in two tibial tunnels and two femoral tunnels. The first tunnel to be built is the anteromedial (AM) femoral tunnel, through femoral guide inserted into the AM portal in the 10:30 h position for the right knee and 1:30 h position for the left knee, with the knee at 120° of flexion. Then we drill the PL femoral tunnel in its anatomical position from the accessory AM portal, with the knee at 120° of flexion. The next tunnels are the PM and AM tunnels. The PL tunnel has its point of entry anterior to the fibers of the superficial medial collateral ligament, and the tibial guide must be adjusted at 45º. The AM tunnel has its point of entry more lateral, and a bone bridge of at least one cm must be left between the tunnels, and the tibial guide adjusted at 55º. Both bundles must be fixed onto the tibia and femur with a biodegradable interference screw.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Body mass index (BMI), which corresponds to the ratio between weight in kilograms (pounds) and height in m2 (square meters) between 18.5 and 24.99.
3. Anterior instability alone or associated with chondral lesions of up to 1cm or associated with meniscal injuries that do not alter the postoperative rehabilitation.
4. Magnetic resonance imaging (MRI) confirming the ACL injury.
5. Aged between 20 and 45 years.
6. Not having asymmetric varus alignment, greater than or equal to 5 degrees (to eliminate cases with indication for osteotomy of the tibia), using panoramic radiographic comparison of the lower limbs in standing position.
7. Absence of associated ligament instabilities (medial, lateral or posterior).
8. No previous surgery on the affected knee.
Exclusion Criteria
2. Interruption of treatment / follow-up.
3. Postoperative infection.
