Moderated Blood Flow Restriction After Anterior Cruciate Ligament Reconstruction

Anterior Cruciate Ligament Tear

The aim of this study is to determine if there is a difference in post operative rehabilitation after anterior cruciate ligament (ACL) reconstruction surgery while using moderated blood flow therapy vs. standard physical therapy. All patients undergoing ACL reconstruction, between the ages of 18-30, that consent to taking part in the study, and meet eligibility criteria, will be included in the study. Patients will be followed for two years to determine any differences in muscle strength, thigh circumference, knee range of motion, pain, functional and activity levels, patient satisfaction, levels of Human growth hormone HGH), Insulin-like Growth Factor (IGF), and Creatine Kinase (CK), KT2000, and Lachman physical examination.

3D Reconstruction of the Knee Based on MRI

ACL Tear

ACL tear is a pathology of the knee quite common in athletes mainly caused by a twisting movement. The diagnosis of ACL tear can be confirmed by MRI (magnetic resonance imaging). This method makes it possible to visualize the inside of the knee and to diagnose lesions associated with rupture of the ACL (in particular meniscal lesions). Obtaining a 3D model of patients' joints from a imaging is of growing interest to plan the gesture in preoperative but also to evaluate this gesture postoperatively. In orthopedic surgery, the baseline preoperative imaging is MRI. However, 3D models are generally obtained from a scanner-like imaging. In this context, obtaining a 3D model from MRI imaging would make it possible to have a model that fits into the care pathway patients, without subjecting them to irradiation and visualizing anatomical structures not visible on CT. However, the geometric precision and the reproducibility of the 3D reconstructions of joints reconstructed from an MRI remains unknown and must be evaluated to consider their clinical use.

Effect of Blood Flow Restriction Training to Muscle Strength, Dynamic Stability, and ACL Injury...

Healthy SubjectsSports Level 1

The goal of this randomized clinical trial study is to compare low-load blood flow restriction (LL-BFRt), sham LL-BFRt, and high-load eccentric training (HL-Et) in healthy level 1 sportsman. The main questions it aims to answer are: Does LL-BFR improve muscle strength better than sham LL-BFRt and HL-Et? Does LL-BFR improve dynamic stability better than sham LL-BFRt and HL-Et? Does LL-BFR prevent ACL injury better than sham LL-BFRt and HL-Et? Participants will be randomized into three intervention groups: LL-BFRt, sham LL-BFRt, and HL-Et. Participants will be asked to do: In LL-BFRt, participants will be asked to do LL eccentric training (including double leg squats, split squats, deadlifts, and monster walks) with a 30% of repetition maximum (RM) and 70% of arterial occlusion pressure (AOP). In sham LL-BFRt, participants will be asked to do LL eccentric training with a 30% of repetition maximum (RM) and 10% of arterial occlusion pressure (AOP). In HL-Et, participants will be asked to do LL eccentric training with a 70% of repetition maximum (RM). Researchers will compare LL-BFRt, sham LL-BFRt, and HL-Et to see if muscle strength, dynamic stability, and ACL injury prevention improve after the interventions and follow-up.

A New Dual Task Test Method for Football Players

Sports Physical TherapyMulti-Tasking Behavior2 more

Multitasking (Dual Task) is a measurement method to evaluate cognitive ability to execute multiple functions at the same time. To perform this test, while participant/patient performing a main skill (for example, walking), a cognitive skill is added (for example, counting 7 backwards from 100) to measure how much the completion performance of the activity is affected. Frequently used multitasking trainings are known as counting back from 100 and asking mathematical equations during a physical skill. Multitasking skill is rarely used in sports-related training, and it is generally used in the form of counting 7 backwards from 100, counting months and counting 5-letter words while walking over obstacles. However, multitasking training methods described and applied in the literature are not specific to football skills. For this reason, limited tests defined and applied in other clinical and sportive fields may not be sufficient in football players who perform activities that require high performance. Therefore, aim of this study is to develop a dual-task assessment method, which includes the cognitive loads experienced by football players during training and matches, and also covers the basic skills of football. As a result of this study, a football-specific dual-task test will be created and the capacity of the athletes will be measured by applying this test to healthy athletes. Also, this test will be conducted on football players with recent knee injury history, who wish to return to sport, and to evaluate their dual-task capacity and to correlate it with kinesiophobia and other performance tests

Nordic Hamstring Exercise After ACL Reconstruction Reconstruction

ACL InjuryMuscle Weakness1 more

Anterior cruciate ligament (ACL) injuries constitute a significant portion of major knee joint injuries sustained by young, active individuals, and significantly increase risk for long-term disability. Yet the recommended solution to restore joint stability following injury--ACL reconstruction (ACLR)--does not prevent post-traumatic knee osteoarthritis (PTOA). Post-traumatic quadriceps (dys)function is a hallmark characteristic following ACLR, reported to accelerate the onset of PTOA after ACL injury, making the recovery of muscle function a primary concern to clinicians. However, hamstrings muscle function is drastically underrepresented relative to the quadriceps in the context of recovery from ACLR, which impedes the ability to develop targeted treatment approaches. Persistent hamstrings weakness is widely reported in patients who undergo ACLR with a hamstring tendon (HT) autograft, which increases ACL strain, and may contribute to higher graft failure rates in this population. To effectively treat muscular impairments, underlying neuromuscular adaptations known to occur in response to ACLR must be targeted. Eccentric exercise is uniquely suited to enhance neuromuscular function. The Nordic hamstring exercise (NHE) is a specific form of eccentric exercise that is clinically relevant and easy to implement, but has not been explored as an intervention for hamstrings neuromuscular dysfunction in patients who undergo ACLR with HT. To establish an evidence-based treatment model, the investigators will use a single-blind, randomized controlled clinical trial to establish the feasibility and efficacy of a 4-week NHE protocol in patients who undergo ACLR with HT. Separate factorial ANOVAs will be used to assess the effects of group (NHE, control) and time (baseline, 4 weeks) on selected outcomes. Effect sizes will be calculated for within- and between-group comparisons. The investigators expect to observe improvements in hamstrings neuromuscular function following the NHE protocol, and that those improvements will be greater than the control group. Additionally, the investigators expect the protocol to be feasible in terms of intervention adherence and patient retention. This study will identify specific barriers to the implementation of NHE in patients who undergo ACLR with HT, and will provide support for the application of an easy to implement clinical intervention able to address a complex neurophysiological problem.

The Effectıveness Of Structured Myofascial Chain Exercise Training After Anterior Cruciate Ligament...

Anterior Cruciate Ligament InjuriesAnterior Cruciate Ligament Rupture1 more

Anterior cruciate ligament reconstruction(ACLR) surgery accepts best choices which condicions are totaly ruptured ACL or partial ruputures when patients with high activity level. Rehabilitation after ACL is an indispensable element of treatment because ACL injury causes severe instability and early degenerative changes in the knee. Although there is no standard rehabilitation program after ACLR but the concept of "Functional Rehabilitation" is prefers nowadays which structred according to therapeutic goals, it is planned in three stages as early, mid-term and late-term. After the late-term goals are achieved safely and the individuals reach to needed criterias, the stage of returning to sports or activity is planned. Patients with an active life expectancy, the goal at the end of rehabilitation after ACLR is to return to activity or sports and to reach pre-injury performance. Most individuals fail to return to sports or activity after ACL due to long-term strength deficits, neuromuscular and biomechanical changes, knee instability, and early developing knee osteoarthritis. Addition to that; changes that affect both the knee joint and the whole body biomechanics occur even in individuals who successfully return to activity and sports after ACL. Although there are problems that affect the whole body by exceeding a single segment in rehabilitation after ACLR; there is no study using the myofascial chain exercises approach in the treatment of these problems. Hip, core or trunk stabilization exercises and neuromuscular trainings that include more than one body segment added to the ACLR program provides more positive effects on rehabilitation outcomes than regional applications. In this project, researches aim to investigate that the effectiveness of structured myofascial chain exercises training, which will be applied in the late period of rehabilitation after ACLR, on functionality, performance and participation.In project scope; After completing the early and mid-term rehabilitation after surgery, the volunteers who met the criteria for transition to late rehabilitation were divided into two groups; lower extremity exercise training will be given to the first group and myofascial chain exercise training will be given to the second group. The control group will consist of healthy volunteers. In addition to the control group; The operated and intact extremities of the volunteers in the experimental groups will be compared. The training session, in which preterm and postterm evaluations and the exercises are taught, will be carried out with the face-to-face method, and the ongoing exercise sessions will be carried out with the telerehabilitation method. Reasearch outcome measures will be evaluated with strength, flexibility, balance, endurance, activity performance against time measurements and self-assessment questionnaires. End of this project; important data will be obtained in the fight against the risks created by the deficits that continue after the ACLR. The deficits seen after ACL fails to individuals from returning to their pre-injury functional level; the desired success cannot be achieved in returning to work, returning to sports, and returning to activity. Due to this situation, which poses a global problem, even if there is a return to work or sports after injury, branch and job changes may be required and the desired level of performance cannot be achieved. In individuals who cannot return to activity, inactive life increases the risk of non-communicable chronic diseases as well as the increased risk of osteoarthritis. In case of success in the project, important information will be obtained in order to prevent both the quality of life and the cost of secondary health and social life problems associated with ACL injuries. The content of the program will be expanded to include other sports injuries by applying to follow-up projects for the registration of the method to be applied for the first time.

Blood Flow Restriction to Improve Muscle Strength After ACL Injury

Anterior Cruciate Ligament Injury

Quadriceps muscle weakness is a common consequence following anterior cruciate ligament (ACL) injury and reconstruction. Maximizing quadriceps strength following ACL injury is significant as diminished quadriceps strength has been linked to the osteoarthritis that affects over 50% of surgically reconstructed limbs. Given that knee joint health following ACL injury is predicated on restoring quadriceps strength, identifying treatment approaches capable of improving strength is paramount. Blood flow restriction training (BFRT) is a method where oxygen to the muscle is intentionally reduced during exercise/rehabilitation and may lead to more timely and substantial strength gains. In the proposed project, we will examine the efficacy of BFRT in patients who have undergone ACL reconstruction and suffer from substantial quadriceps weakness.
