The purpose of this study is to assess the intra-operative and post-operative effects of tourniquet use during ACL reconstruction. We hypothesize that: 1. Limited tourniquet use will not significantly impact arthroscopic visualization nor the time it takes to complete an ACL reconstruction. 2. Limited tourniquet use will lead to significantly less patient pain intra-operatively and in the immediate peri-operative period. 3. Patients who undergo an ACL reconstruction with limited tourniquet use will have earlier return of quadriceps functions as compared to those undergoing reconstruction with the use of a tourniquet.

Anterior cruciate ligament (ACL) surgery patients experience physical trauma, both in the physical injury itself and following surgery, and face potential long-lasting adverse effects such as muscle weakness, diminished joint function, hip pain, and fear. Many of these patients report more significant anxiety and depression following surgery, which can further compound these patients' adverse outcomes. This study is a single-blind, randomized controlled trial design to evaluate the effects of a remotely-delivered 8-week mindfulness intervention on patient-reported outcomes (PROs) following ACL reconstruction surgery.

The purpose of the research is to investigate the effect of preoperative Cryoneurolysis of the knee on postoperative pain management in patients undergoing autograft anterior cruciate ligament (ACL) reconstruction (a surgical procedure that makes a new ACL using the patient's own tendon). Cryoneurolysis is an approved process of applying extreme cold temperatures to targeted nerves in order to decrease or eliminate pain. . If you take part in the research, you will be randomly assigned (assigned by chance, like a flip of a coin) to Group A (standard care) or Group B (standard care plus Cryoneurolysis). Participants in both groups will undergo standard ACL reconstruction and receive standard preoperative and postoperative pain management. Participants in Group B only will also receive a standard treatment of Cryoneurolysis to their surgical knee within 7-10 days before their scheduled surgery. Participants in both groups (A \& B) will be asked to bring their remaining postoperative pain medication to their postoperative follow-up appointments for review by study personnel. Participants will also be asked to complete a survey about their knee activity, function and symptoms at these appointments. Your time in the study will last until the completion of the 12-week postoperative follow-up appointment.

Optimal knee joint loading, which refers to the forces acting on the knee caused by daily activities such as daily steps, plays an essential role in maintaining knee articular cartilage health and reducing the risk of osteoarthritis (OA). After anterior cruciate ligament reconstruction (ACLR), individuals take fewer daily steps as compared to uninjured controls resulting in insufficient knee joint loading to joint tissues, but it is unclear how changes in daily steps impact knee joint cartilage health in OA development. Therefore, the overall single arm, longitudinal pre-test post-test study objective is to determine the mechanistic links between knee joint loading as measured by daily steps and comprehensive magnetic resonance imaging (MRI) measures of knee joint cartilage health post-ACLR. The central hypothesis is that individuals post-ACLR who take low daily steps will demonstrate deconditioned, less resilient cartilage characterized by poor tibiofemoral cartilage composition and greater cartilage strain.

Loss of skeletal muscle mass (atrophy) and strength in the lower limb are consequences of elective knee surgery as result of prolonged disuse from limb immobilization and impaired mobility, as well as pathophysiological trauma. The highest rates of skeletal muscle mass and strength loss occur during the 2-week post-surgery period, considered the early phase of outpatient recovery. Alternative to resistance exercise and pharmacology, nutritional intervention represents one strategy to combat skeletal muscle disuse atrophy. Essential amino acids (EAA) and omega-3 fatty acids are known to independently potentiate rates of skeletal muscle protein synthesis and attenuate skeletal muscle atrophy in humans. However, the combined actions these nutritional strategies on skeletal muscle have not been explored in a pathophysiological context, such as surgery. With the ultimate goal to test the efficacy of the combined nutritional strategy to attenuate skeletal muscle disuse atrophy in the future, the aim of this present pilot study is to explore the feasibility of recruitment and retention of anterior cruciate ligament reconstruction (ACLR) outpatients from a single centre across 18 months for a 6-week nutritional intervention. Participants will consume either an intervention of omega-3 fatty acids and EAAs, or a placebo control of safflower oil and non-essential amino acids (NEAA), for 4 weeks before and 2 weeks after elective ACLR surgery. Furthermore, this pilot will characterize secondary outcomes of skeletal muscle mass, strength, and power, and integrated rates of muscle protein synthesis, as well as report participant adherence to protocols and incidence of adverse events.

This trial is testing whether adding an internal brace during ACL surgery helps patients recover faster and have better outcomes. It focuses on young adults and athletes who need strong and stable knees. The brace is supposed to make the new ligament stronger and more stable while it heals. Internal bracing of the anterior cruciate ligament (ACL) reinforces the ligament and encourages natural healing by protecting it during the healing phase and supporting early mobilization.

The goal of this pilot clinical trial is to compare anterior femoral cutaneous nerve block (AFCN) to adductor canal block ACB) for pediatric patients undergoing either anterior cruciate ligament (ACL) or medial patellofemoral ligament (MPFL). The aims of this trial are: * To measure postoperative functional outcomes in patients who received AFCNB vs. ACB. * To calculate postoperative opioid requirements in pediatric knee surgeries that received AFCNB vs. ACB. * To calculate pain intensity levels at rest and with ambulation in patients who received AFCNB vs. ACB. * To quantify sensory deficits in patients who received AFCNB vs. ACB. * To assess patient-reported outcome measures (e.g., pain expectation scale, pain management satisfaction, PROMIS Pediatric Short Form v1.0 - Physical Activity, PROMIS Scale v1.2 - Global Health) in patients 8-18 years of age who received AFCNB vs. ACB. Subjects undergoing ACL procedures will be compared between those who received the adductor canal block to those who received the anterior femoral cutaneous nerve block. The researchers will also compare individuals who underwent MPFL procedures and received an anterior femoral cutaneous nerve block with those who received the adductor canal block. Participants will: * Be randomized to receive either the AFCNB or ACB in addition to standard of care analgesia. * Maintain a patient diary to document daily pain meds/pain scores * Complete follow up surveys/questionnaires via telephone and during their office visits with surgeons.

KneeStim for ACL Injury

West Point, New York
The goal of this clinical trial is to examine the effects of 12 weeks of post-operative use of a novel wearable electrical stimulation knee sleeve device (KneeStim) on post-operative biomechanical function (gait). Participants will be United States Military Academy cadets aged 17-27 years. The main questions it aims to answer are: * Examine the effects of KneeStim wear on cadets' post-operative gait * Examine changes in site-specific skeletal muscle mass * Examine the changes in patient-reported outcomes * Assess time to return to full duty * Compare Bioelectrical Impedance Analysis (BIA) measurements to Magnetic Resonance Imaging (MRI) measurements (total thigh volume) * Determine the concurrent criterion validity of the KneeStim device compared to gold- standard metrics (3D Motion Capture) Participants will undergo body composition analysis, MRI, strength testing, standard of care rehabilitation, gait analysis, and complete surveys. Participants will wear the KneeStim during their standard of care rehabilitation visits for the first 5 weeks post-operative, and throughout daily tasks from 6-12 weeks. Researchers will compare a control group (standard of care + KneeStim controlled low intensity) to an experimental group (standard of care + KneeStim flexible intensity) to assess the aims previously mentioned..

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

While there are a number studies that have reported on the use of blood flow restriction training (BFRT) in the adult population, there is limited information about the use of BFRT in the adolescent population. This study aims to evaluate the use of BFRT in conjunction with traditional anterior ligament reconstruction (ACLR) rehabilitation in adolescents. The purpose of this study is to compare the addition of a BFRT based exercise protocol to a standard ACL rehabilitation protocol in adolescents. Does the addition of BFRT-based exercise improve strength, hypertrophy, and patient reported outcomes after ACLR in the adolescent population?

The overall goal of this project is to reduce risk of second anterior cruciate ligament (ACL) injury in vulnerable populations (active athletes between 14 = 24 years old) through the identification of relative injury risk groups based on subject-specific movement patterns prior to second injury, as well as through the determination of effect for differential rehabilitation protocols following initial ACL reconstruction and prior to return to sport. As nearly one-third of athletes who have a primary ACL injury and return to sport will experience a secondary injury, results from the proposed work will allow us to prospectively identify high risk patients who are the most appropriate recipients of enhanced treatment, including targeted training, which may reduce the risk of second ACL injury. Secondary ACL injury has the potential to end athletic careers, promote the development of osteoarthritis, and have debilitating effects on quality of life. Hence, the information gathered in this investigation will offer ACL injured athletes the optimal potential to reduce or potentially prevent these negative health effects before they are initiated.

The purpose of this study is to examine ACLR Rehabilitation with Exercise and Psychological Support (REPS), comparing two approaches for providing psychological support along with exercise during ACL reconstruction rehabilitation. In one group, physical therapists have received training that may boost emotional support during rehabilitation. In the other group, physical therapists will not have the training. Both groups will get similar exercises and participate in the same testing. Both groups will also watch short videos during rehabilitation that are specific to their group. Participants will not know to which group they are assigned until the end of the study. Participation will attend a total of four study visits over the course of 6 months, including 1 visit before the surgery and 3 visits during follow-up.

This study aims to determine the feasibility of implementing a mental skills training intervention for adolescent athletes who tear their ACL and undergo ACL reconstruction surgery alongside receiving standard-of-care clinical treatment. The study will also determine if the mental skills coaching program has any effect on the psychological readiness of patients to return to sport after undergoing surgery and postoperative recovery and rehabilitation. If feasible and if the mental skills training program shows promising effect on athletes' confidence in returning to sport, a large-scale clinical trial can be explored to assess the relationship between mental skills' impact on readiness to return to sport, which could in turn provide evidence on the benefits of integrating mental skills directly into standard clinical care.

Frequently Asked Questions

How much do Acl clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Acl clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Acl trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Acl is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Acl medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.
