The anterior cruciate ligament (ACL) is one of the main stabilizers of the knee joint, and its injury is among the most common soft tissue injuries of the knee. Several surgical reconstruction techniques are available, utilizing various tissues as a graft for the neo-ligament, including both autografts and allografts. The "Over-the-top single-bundle technique with gracilis and semitendinosus tendons combined with lateral extra-articular tenodesis (LET)" was developed in 1998 by Prof. Marcacci and Prof. Zaffagnini, and it is still the preferred method for ACL reconstruction at the Second Clinic of the Rizzoli Orthopaedic Institute. Cadaveric biomechanical studies have shown that combining LET with ACL reconstruction improves knee joint stability in both the anteroposterior and rotational planes. However, a recent in vivo study has challenged this hypothesis, showing that in patients undergoing surgery, the addition of LET enhances knee stability only in the anteroposterior direction and only for a limited period of six months. At twelve months postoperatively, joint laxity appeared similar to that of patients who did not undergo the additional procedure. Furthermore, the same study did not assess rotational instability using the pivot-shift test, an essential parameter as it is closely linked to knee stability and the patient's subjective perception of surgical success. Despite the increasing use of LET in conjunction with ACL reconstruction, few studies have analyzed the short-term postoperative effects of lateral extra-articular tenodesis and its potential benefits during the early stages of rehabilitation and return to sport. This study was conceived in response to this clinical question, with the goal of evaluating anteroposterior and rotational laxity in a group of patients who underwent ACL reconstruction combined with LET, in order to analyze clinical outcomes and, most importantly, any changes in stability during the early postoperative period. The results aim to improve understanding of knee stability in the initial phase following surgery, providing valuable information for rehabilitation teams to optimize recovery protocols and more effectively guide return-to-sport decisions for patients undergoing both procedures.

Psychological factors play a critical role in recovery following anterior cruciate ligament (ACL) reconstruction. While tools such as the ACL - Return to Sport after Injury (ACL-RSI) focus on psychological readiness, emphasizing fear, hesitation, and apprehension, the opposite spectrum-overconfidence and risk-taking behaviors-remains underexplored. These behaviors can lead to premature return to high-risk activities and an increased likelihood of re-injury. To address this gap, we propose the development and validation of the RISE-ACL scale for assessing Risk-taking Intention and Sport Engagement after ACL reconstruction. This scale will assess key factors such as patients' willingness to engage in high-impact activities, their adherence to medical guidance, and their perceived readiness to resume sports despite potential physical or psychological limitations. The RISE-ACL Scale will complement existing tools like the ACL-RSI by focusing on overconfidence and risk-taking, offering clinicians a more balanced perspective on psychological recovery. Validation of the scale will involve testing its validity, reliability and clinical utility to ensure accurate identification of at-risk individuals. By providing actionable insights, the RISE-ACL Scale will help enhance post-operative care, promote safer return-to-play decisions, and optimize long-term outcomes through a comprehensive assessment of psychological and behavioral factors.

After reconstruction of the anterior cruciate ligament, the aim for the vast majority of sportspeople is to return to the field. To date, 65% of patients who have undergone ACL rehabilitation return to their previous level, and 55% return to competition. To achieve this, physiotherapy sessions need to prepare the return to sport as well as possible, by simulating the cognitive demands (reading the game, double task, etc.) that might be encountered on the pitch. Tests to assess the athlete's performance do exist, in order to optimise this return to sport, but they do not include the cognitive tasks that are present in sport. The high cognitive demands of the sporting environment therefore justify the inclusion of cognitive tasks in these return to sport tests. The aim of this research is to assess the impact of the cognitive task on the performance of a return to sport test following ACL reconstruction. Patients who have undergone ACL reconstruction and healthy subjects will therefore be given a return to sport test called the 'Single Leg Hop for Distance' with and without a cognitive task in order to observe the influence of the cognitive task on the results of the hop. Including healthy subjects in this study will make it possible to study the impact of the cognitive task in these subjects, who have no neurophysiological dysfunction linked to ACL reconstruction. The aim of this study is therefore to try to develop the return to sport tests currently described in the literature by proposing a new, improved test that takes account of the cognitive dimension, which is omnipresent in the sporting environment.

After anterior cruciate ligament reconstruction (ACL-R), Single Hop for Distance (SHD) performance aids in decision-making, particularly for return-to-sport assessments. However, asymmetrical landing kinematics are common after ACL-R, even with symmetrical performances, and increase the risk of re-injury. To support clinical practice, several qualitative scales have been developed as valid and reliable tools for assessing landing quality. In 2022, Measson et al. adapted the Landing Error Scoring System for use during an SHD task (SHD-LESS scale) and demonstrated its reliability among healthy individuals. The aim of this study is to test the validity of this scale after ACL-R by evaluating its ability to identify asymmetrical landing and characterize differences between the operated and uninjured limb. The second objective is to assess its association with knee muscle strength, functional status and psychological readiness.
NCT03096366
The purpose of this study is to evaluate the effectiveness of physical therapy (PT) plus BFR training compared to PT alone (without BFR training) after ACL reconstruction in patients who require extended limited weight bearing through assessment of patient reported outcomes and functional testing. The hypothesis is that PT plus BFR training will mitigate the loss of quadriceps muscle cross-sectional area, strength, and function while also improving early clinical and functional results.
NCT01595581
This study is being done to test whether taking testosterone can prevent loss of muscle mass and strength due to anterior cruciate ligament (ACL) reconstructive surgery. Testosterone is the principal male sex hormone and an anabolic (muscle promoting) steroid. It is essential for the development of male reproductive tissues and promotes increased muscle, bone mass, and the growth of body hair. The investigators hope to learn whether testosterone given before and after ACL reconstructive surgery will increase muscle mass and strength and potentially improve recovery time following surgery.

This was a prospective, multicenter, randomized, open-label, phase IV trial to compare the efficacy of supplementation with plasma proteins, hydrolyzed collagen (CH), a complex of HA-CS (HC-15), and vitamin C combined with a standard rehabilitation protocol versus the standard rehabilitation protocol only after arthroscopically-assisted functional ACL reconstruction with hamstrings.
