About this study

Official title: Association of Anterolateral Ligament and Anterior Cruciate Ligament Reconstruction Lead to Superior Outcomes and Lower Failure Rates in High-risk Population?: a Randomized Controlled Trial.

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.

Read the detailed description

Rotational knee stability is a topic with great interest among Anterior Cruciate Ligament (ACL) Reconstruction experts. Previous papers have questioned whether current ACL reconstruction techniques may provide adequate rotational stability in all ACL-deficient individuals, considering their broad spectrum of clinical presentations (Logan 2004, Ristanis 2005). 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). Besides, lack of knee stability could lead to further chondral and meniscal lesions, which could enhance development of knee osteoarthritis (Stergiou 2007).

This discussion has gained increased attention after recent publications regarding the Anterolateral ligament (ALL), described as a structure whose lesion seems to worsen rotational instability when associated to ACL ruptures. (Claes 2013, Helito 2013, etc). Segond first described this ligament in 1897 as a "resistant fibrous band" located in the anterolateral knee compartment with a singular characteristic of tensioning in forced internal rotation (Segond 1879). Afterwards, some authors referred to this structure as a capsular thickening (Hughston 1976). More recently, various anatomical publications brought up this controversy, defining the ALL as a distinct ligament (Claes 2013, Dodds 2014, Helito 2015). Biomechanical data have shown straight correlation between its rupture and worsening of rotational stability, defined with a presence of an obvious positive pivot shift test (Claes 2013, Monaco 2012). Lack of consensus still exists regarding the validity of these findings, but many authors proposed the association of ACL and ALL reconstruction in selected ACL-deficient individuals, considering the theoretical biomechanical advantage of this procedure in promoting combined anteroposterior and rotational stability (Sonnery-Cottet 2015, Sonnery-Cottet 2017, Dodds 2014, Marcacci 2009). In a recent meta-analysis of randomized controlled trials, isolated ACL reconstruction techniques were compared to combined ACL and extra-articular reconstruction techniques and, although Lachman and pivot shift tests were superior in the combined ACL reconstruction group, functional scores were similar (Rezende 2015). Knee stiffness and infection, were also similar between groups, despite previous publications suggesting increased rates in the combined procedure (Anderson 2001, Sonnery-Cottet 2011). However, considering the lack of improvement of knee scores tests, the authors concluded it is still uncertain whether this increased stability surpasses the morbidity of adding an extra-articular procedure (Rezende 2015). In contrast to the obsolete extra-articular techniques included in the latter meta-analyses, anatomical ALL reconstruction techniques have been proposed to better replicate the anatomy of the anterolateral compartment (Sonnery-Cottet 2015). Promising results have been published in a recent prospective cohort study comparing combined ALL and ACL reconstruction with isolated ACL reconstruction techniques, using either hamstrings and bone-patellar-tendon bone grafts. Re-rupture rates were 3.1 times fold less in combined ACL and ALL procedure compared to isolated ACL with hamstrings and 2.3 times fold less compared to isolated ACL with bone-patellar-bone graft . The percutaneous ALL reconstruction technique described in this study not just reproduces more reliably the anatomy of the anterolateral compartment, but it is also less invasive diminishing the morbidity associated with the non-anatomic extra-articular reconstruction techniques, such as the iliotibial band tenodesis (Sonnery-Cottet 2017).

Many controversy still predominates among ACL experts not just regarding ALL in vitro studies, but also the debate about the reliability of the combined ACL and ALL procedure when bringing it to the clinical setting (Guenther D 2016, Kittl C 2016). Concerns have been raised about some aspects of the combined ACL and ALL procedure, in particular its theoretical potential in leading to an excessive knee constriction, as demonstrated in some biomechanical papers (Schon JM 2016). Experts opinions diverge about the potential long-term consequences of the combined ACL and ALL procedure; while defenders state that improved rotational instability should minimize degenerative consequences of a "sub-optimal" knee joint stability supposedly provided by an isolated intra-articular reconstruction, many other surgeons argue that knee osteoarthritis might the evolution of the abnormal kinematics of an overconstrained knee (Inderhaug E 2017, Schon JM 2016, Sonnery-Cottet B 2017). In order to resolve such lack of consensus, clinical trials with high level of evidence should be the priority in this field, with a long term follow-up, aiming to compare functional scores, knee stability tests and complications rates between isolated ACL and combined ACL and ALL reconstruction techniques.

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Isolated anatomic ACL reconstructionProcedure or surgery

    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.

  • Combined Anterior Cruciate Ligament and Anterolateral Ligament reconstructionProcedure or surgery

    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 tunnel will be performed with a 5mm drill, 1cm distal to the articular level, midway from the fibular head and Gerdy Tubercle, crossing the tibia toward its anteromedial cortex, 1cm distal to the ACL tunnel. 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 tunnel and then retrieved in the anteromedial aspect of the tibia, 1cm distal to the ACL tunnel entrance. ALL is fixed in full extension and neutral rotation, tying both graft extremities with 3 knots.
