Reconstruction of anterior cruciate ligament (ACL) is a common procedure in orthopaedic surgery, aimed at restoring stability to your knee. This procedure involves performing an anterior cruciate ligament (ACL) graft and an anterolateral ligament (ALL) graft. Despite technological advances and improvements in surgical techniques, failure rates remain high. In this context, a better understanding of knee movements (the position of the femur and tibia, as well as the ligaments) during flexion whilst reconstructing your ACL could improve the precision of reconstructions and reduce the long-term failure rate. Using a surgical navigation system, it is possible to record data on the positioning of the femur and tibia during flexion and extension. This type of morpho-functional analysis of knee kinematics during ACL reconstruction has never been carried out before.

The aim of the EMBRACE clinical trial is to compare outcomes (knee pain, symptoms, function and quality of life) between people with anterior cruciate ligament (ACL) rupture who are managed with either a novel bracing protocol (Cross Bracing Protocol), or with ACL reconstruction surgery. The main question that the trial aims to answer is: In individuals with acute ACL rupture, is management with the Cross Bracing Protocol more clinically effective and cost effective compared to early ACL reconstruction surgery? 180 people across five Australian cities, with a recent ACL injury, will be randomly allocated to one of two treatments. 1. Cross Bracing Protocol People who are allocated to the bracing treatment will: * wear a knee brace for 12 weeks * see a sports doctor * have 23 visits to a physiotherapist who will supervise their knee rehab over 12 months. * have two knee scans; 3 and 18 months after they enrol 2. Anterior Cruciate Ligament Reconstruction Surgery People who are allocated to the surgery group will: * have surgery within 8 weeks of enrolling in the study * have 15 visits to a physiotherapist for their knee rehab over 12 months after surgery. * have one knee scan 18 months after they enrol. All participants will: * complete surveys at the beginning and 3, 6, 12 and 18 months later so the main trial outcomes can be collected, as well as additional information about their knee. * have knee imaging (Magnetic Resonance Imaging or MRI scan) so the overall condition of their knee can be assessed, as well as whether their ACL has healed.

Anterior cruciate ligament (ACL) injury is a prevailing problem among sports participants, especially in non-contact sports. Studies have reported that 70-84% of ACL injuries are non-contact in nature, and movements like changing in direction while running, cutting and pivoting on a planted foot have resulted in a majority of ACL injuries. Even after ACL reconstruction (ACLR) surgeries, study has reported a 30-50% prevalence of developing patellofemoral joint (PFJ) pain in 1-2 years post-operation. Whole body vibration (WBV) therapy has been gaining attention as an effective method of training in recent years. It has been proved to have a positive effect on improving muscle strength, muscle activities, muscle power and loading during drop jump. Though duration of WBV may differ according to the effect of interest, several studies have had positive results with a 8 week WBV therapy in increasing muscle strength, proprioception, and post-ACLR knee functions. Further investigation on the underlying mechanism and possible application are to be continued to explore more possibilities with the WBV therapy.

Anterior cruciate ligament (ACL) injury is the most common knee injury among athletes who play contact sports involving pivoting. ACL reconstruction (ACLR) combined with rehabilitation is the standard treatment for ACL tears in athletes, and rehabilitation is one of the keys to success. The overall return to sport rate is 80%, but the return to pre-injury level of sport is only 65% and the return to the same level of competition is only 55%. The recurrence rate is close to 20%. During rehabilitation and sports practice, proprioceptive information is essential for adjusting the muscle sensorimotor loop and enabling optimal movement. Athletes can thus be classified as plastic or rigid . Our hypothesis is to show that the proportion of "plastic" patients 9 months post-operative following ACL reconstruction is higher than that found in the same population 3 months post-operative, thus demonstrating the progression of proprioceptive integration abilities after ACL reconstruction surgery.
NCT07333092
The aim of this study is to investigate the effects of proprioceptive exercises on balance, kinesiophobia, and functionality after anterior cruciate ligament surgery.
NCT07043569
With the intention of improving rehabilitation after anterior cruciate ligament reconstruction, the present project investigates the influence of a targeted strength and blood flow restriction training intervention (BFR training) on the regeneration of muscle mass, strength and functionality of the knee joint. BFR training is characterized by the combination of external venous vascular occlusion with light strength training and still enables users to achieve gains in muscle mass and strength that are comparable to training with high mechanical loads. The positive effects of BFR training in the course of knee arthroplasty have already been demonstrated by our working group as a prehabilitative approach, i.e. as a training intervention prior to surgery. In the present project, the framework conditions of outpatient rehabilitation at the Bonn Center for Outpatient Rehabilitation will now be used to prove whether sports science-controlled strength and BFR training has a similar effect in the postoperative rehabilitation phase. The interventions are carried out as part of the exercise therapy units in outpatient rehabilitation ETM01 in accordance with the S2k guideline on anterior cruciate ligament rupture. Strength and BFR training in medical training therapy supplements the daily exercise therapy to ensure implementation in the rehabilitation process in line with the guidelines.
NCT03365908
This study will compare the outcome of pain interventions that are considered standard of care during the surgical treatment of ACL injuries. The comparison will be looking at pain control during and after ACL surgery as well as functional outcomes in patients that had a nerve block versus those who did not. The investigators hypothesize that pain control will be equal between both groups.

ACL injuries are incapacitating for both professional and amateur athletes, with long-term repercussions on performance and return to sport (RTS). Surgical reconstruction of the ACL is the main treatment option. Despite this, recurrence rates are high. Half of all recurrences occur within 8 months of reconstruction, and 70% within the first 6 months after RTS. Decision to RTS is therefore an important one, as returning too early can increase the risk of recurrence, while returning too late delays a return to pre-injury performance levels. As described by the Bern Consensus, RTS consists of three phases : * Phase 1: Return to participation (RTp) * Phase 2: Return to sport (RTS) * Phase 3: Return to performance (RTP) RTS decision must be based on multiple factors, including psychological, athletic and functional components, as well as specific nature of the patient's activities. However, few individual tests have been associated with a specific level of RTS. Furthermore, the majority of studies rely on subjective and non-objective assessments to determine whether the athlete has returned to their pre-injury level. It would therefore be relevant to study the RTS time of patients who have performed a combination of several objective functional tests whose results could be complementary, in particular the K-STARTS, the CMJ, the DJ and the measurement of soleus muscle strength.
NCT07129694
A randomized, multicenter study comparing the safety and efficacy of CT-ACL001, a regenerative ligament, with standard treatment in anterior cruciate ligament reconstruction
NCT07023653
This study aims to compare the functional outcomes of patients with ACL rupture following ACL reconstruction surgery using hamstring grafts, between the all-inside technique and the complete tibial tunnel technique. The hamstring graft, which serves as the tissue substitute for the damaged ACL, is harvested from the posterior thigh of the patient and used to replace the torn ligament during reconstruction
NCT07009392
Anterior cruciate ligament (ACL) reconstructions are common surgical procedures, but a significant number fail for reasons that are not fully understood. Silent infections have been shown to cause failure after other orthopedic surgical procedures such as fracture fixation and joint replacement. Silent and subclinical infections, as well as disruptions in the knee joint microbiome, could therefore be potential causes of failure after ligament reconstruction. Traditional infection diagnostic methods (microbiological cultures) are often inadequate to detect these silent infections due to a lack of sensitivity. New molecular techniques such as high-throughput sequencing or NGS (next-generation sequencing) overcome this sensitivity problem and have proven effective in diagnosing polymicrobial infections. Increased sensitivity compared to traditional culture has been reported in numerous studies, with some demonstrating the ability of NGS to isolate the infectious organism(s) in up to 82% of culture-negative cases. These studies demonstrate the importance of advanced sequencing technologies for the diagnosis and management of infections after ACL reconstruction, offering promising prospects for improving clinical outcomes. At the Jean Mermoz Private Hospital, ACL reconstruction is performed using a graft that is previously immersed in vancomycin. In this context, this study will characterize the knee joint microbiome in the context of ACL reconstruction with a graft treated with antibiotics.
NCT05323474
Following reconstruction of the anterior cruciate ligament (ACL), a standardized rehabilitation protocol is carried out by a physiotherapist. In France, a well-established rehabilitation consensus guides the first phase of 3 months postoperatively and patient compliance is generally excellent. The next phase should allow a return to sport (RTS) following a continuum depending on the objectives of the sport's patient, starting with a return to running activities (RTR) and a preparatory phase for a RTS which may be authorized at 6 months post-op. This multicentre randomized control trial aims to evaluate the effectiveness of an individualized and optimized rehabilitation program guided by monthly assessments carried out by physiotherapists from the 3rd to the 6th month postoperatively to reduce the risk of new ACL injuries (operated or healthy knee), compared to standard management.
NCT06979804
The goal of this clinical trial is to determine the effect of semiconductor sleeves on the treatment of Anterior Cruciate Ligament (ACL) or Anterior Cruciate Ligament and Meniscus (ACL+Meniscus) arthroscopic surgery. The effect of the sleeves will be analyzed through patient reported and clinically measured outcomes. The main questions it aims to answer are: * Do the semiconductor sleeves improve the functional outcomes compared to the placebo? * Will patients experience improved functional outcomes in a shorter period of time compared to the placebo? Researchers will compare semiconductor fabric sleeves to a placebo (a look-alike sleeve that contains no semiconductor material) to see if the semiconductor fabric better treats ACL and ACL+meniscus surgical patients. Participants will: * Wear semiconductor or placebo leg sleeve for 4 weeks and knee sleeve for the following 12 weeks * Complete patient reported outcome surveys
NCT04998656
The aim of this study is to compare the outcomes, ease of use, and cost of the Werewolf FLOW50 device to the institutional standard of care which is does not include the use of electrocautery devices during anterior cruciate ligament reconstruction (ACLR) surgery in patients 12-18 years of age using a randomized control trial design. The investigators hypothesize that a lower proportion of participants who undergo ACLR and are randomized to the Werewolf FLOW50 procedure will experience post-operative arthrofibrosis compared to those randomized to standard of care (control group).

Quadriceps muscle strength is one of the key determinants for patients to fulfill the Return-to-Play (RTP) criteria after an anterior cruciate ligament reconstruction (ACLR), in which the muscle size is directly linked to muscle strength. Quadriceps muscle atrophy is unavoidable after ACLR, but the rehabilitation program should increase quadriceps muscle mass. However, despite good rehabilitation compliance, some patient's progress is sub-par and fail to regain muscle mass. Quadriceps muscle atrophy can persist beyond the completion of the rehabilitation program in almost half the patients and the reason behind this is still unknown. This represents an area that requires significant investigation, as quadriceps muscle atrophy and weakness have been shown to be determinants of poor knee function, decreased performance in sports and increased risk of reinjury. Quadriceps muscle atrophy after ACLR is well documented. This can be due to a decreased ability to regain muscle mass with rehabilitation. Athletes are one of the high-risk groups for vitamin D insufficiencies. Vitamin D deficiency can potentially result in decreased hypertrophy when exercising the muscle, leading to a poorer outcome in rehabilitation. Vitamin D has long been recognized for its effect on musculoskeletal health. It can have a direct effect on muscle hypertrophy by acting on specific vitamin D receptors (VDRs) on myocytes, and sufficient or increased levels of vitamin D in patients have been found to correlate with an increase in the size, number, and strength of muscle fibres. Quadriceps muscle hypertrophy after ACLR is triggered by exercise training, facilitated by diet and a number of intrinsic factors. As the rehabilitation programs and diets are similar in patients with varying extents of quadriceps muscle atrophy, individual responses (intrinsic factors) to exercise training may account for the resulting persistent quadriceps muscle atrophy. In this study, the investigators hypothesize that the deficiency of vitamin D may contribute to persistent quadriceps atrophy and weakness. With a stringent double-blinded randomized-controlled-trial (RCT) research design, our proposal will then address the research questions: 'Does vitamin D supplements improve the vitamin D deficiency status in patients after ACL reconstruction?', and 'Does vitamin D supplements improve quadriceps muscle strength for patients after ACLR?'
NCT06190223
This study aims to evaluate the clinical and radiological outcomes of patients undergoing anatomical single-bundle anterior cruciate ligament reconstruction with periosteal-patellar tendon-bone autograft and press-fit tibial fixation technique. The study also aims to compare these outcomes with other reconstruction techniques in the literature. The research investigates the results of a novel surgical technique, providing a minimally invasive and faster rehabilitation for patients undergoing surgery due to anterior cruciate ligament rupture. The technique does not use any screws or staples for tibial fixation, but it carries similar risks as existing techniques. The technique, similar to the well-known bone-patellar tendon-bone (BPTB) autograft technique, creates minimal bone defect at the tibial tuberosity. Over time, the defect remodels and causes minimal clinical discomfort. Despite these limitations, the authors expect patients operated with the investigated new technique to experience less postoperative swelling, less pain, faster mobilization, and earlier rehabilitation.
NCT06783062
The primary objective of the study is to evaluate the impact of ACL injury and ACL reconstruction on voluntary activation during maximal voluntary contraction (measured by neurophysiological parameters) according to the contraction mode. The goal is to provide elements of knowledge to clinicians about the mechanisms of the activation failure depending on contraction mode, but also the resulting adapted clinical recommendations for conducting rehabilitation, and particularly for the use of different contraction modes. The main hypothesis is that activation failure is not equal according to the contraction mode during maximal voluntary contractions and neurophysiological parameters will be decreased in comparison with non-injured subjects. Secondary objectives are: * To analyze the evolution of neurophysiological parameters between sessions interspaced by several months according to the contraction mode. * To observe this time evolution depending on the treatment strategy chosen: rehabilitation or surgery plus rehabilitation.
