Persistent rotational instability after standard ACL reconstruction have been extensively described, and it has been shown to keep straight correlation with worse outcomes post-operatively (Chouliaras 2007, Kocher 2004). Anterolateral ligament (ALL) injury have been shown to play a relevant role in the genesis of rotational instability of the knee (Claes 2013, Helito 2013). Many anatomical publications have defined the ALL as a distinct ligament (Claes 2013). Meanwhile, some authors have proposed the association of ACL and ALL reconstruction in selected ACL-deficient individuals to further enhance knee stability postoperatively (Sonnery-Cottet 2015, Dodds 2014). Lack of consensus still predominates among ACL experts regarding the reliability of the combined ACL and ALL considering the controversy that involves both ALL anatomy and biomechanics (Guenther D 2016, Kittl C 2016). Clinical trials with high level of evidence and long term follow-up may be useful in order to determine the reliability of the combined procedure in the clinical setting.
So, the present study aims to compare the effectiveness of the combined ACL and ALL reconstruction with isolated ACL reconstruction in individuals with high-risk of ACL re-rupture, through a randomized controlled trial.

|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||80 participants|
|Intervention Model:||Parallel Assignment|
|Masking:||Single (Outcomes Assessor)|
|Masking Description:||Surgeons and participants of the study will not be blinded due to the intrinsic characteristics of the intervention trials, in which it is impossible to blind surgeons and avoid acknowledgement of the participants of which procedure they were assigned. However, outcome evaluation will be performed by an individual who will not have acknowledgement of which group the patient was allocated.|

Active Comparator: Isolated ACL
Standard Anterior Cruciate Ligament Reconstruction only
Procedure: Isolated anatomic ACL reconstruction
Hamstrings free grafts using a two-incision intra-articular Anterior Cruciate ligament (ACL) reconstruction technique. Both ST and gracilis will be prepared with doubled strands, a standard quadrupled graft. The femoral tunnel will be performed in outside-in manner. The tibial tunnel will be drilled in the center of the ACL tibial footprint, sparing the ACL tibial stump, when possible. ACL graft will be first fixed in the femur and then in the tibia, both with an interference screw at 30 degrees of knee flexion.
Experimental: Combined ACL and ALL
Anterior Cruciate Ligament Reconstruction associated with Anterolateral Ligament Reconstruction
Procedure: Combined Anterior Cruciate Ligament and Anterolateral Ligament reconstruction
Hamstrings free grafts using a two-incision ACL reconstruction with the addition of a gracilis prolongation for ALL reconstruction. ACL graft will exhibit a quadruple strand (tripled ST + single gracilis) and the ALL graft, a single strand with the gracilis prolongation. ALL tibial tunnels will be performed 1cm distal to the articular level, 2cm way from one another, midway from the fibular head and Gerdy Tubercle. Femoral ACL and ALL tunnels are coincident and located posterior and proximal to the lateral epicondyle. Intra-articular surgery will be performed in the same manner as comparative group. Gracilis prolongation is routed through the tibial ALL tunnels and then retrieved proximal towards the femoral tunnel. ALL is fixed in full extension and neutral rotation. This is a modification of a previously described technique (Sonnery-Cottet 2015).
