Neuroplasticity Associated With Anterior Cruciate Ligament Injury

ACL Injury

Activation of the brain for knee movement changes after anterior cruciate ligament (ACL) reconstruction. The brain activation profile after ACL reconstruction indicates a shift to a visual-motor control strategy, as opposed to a sensory-motor control strategy to control the knee movement. Recent research suggests that ACL reconstruction rehabilitation protocols should also consider neurocognition and its role in exercise, neuromuscular control, and injury risk to improve the effectiveness of the intervention. However, there is currently no evidence of the feasibility of neurocognitive exercise in a primary rehabilitation program that aims to restore movement function after ACL damage. The purpose of this study is to assess whether conventional ACL injury training with additional cognitive training based on virtual reality is as effective as the sole conventional ACL injury training in participants with ACL injuries.

Improving ACL Reconstruction Outcomes: CBPT

ACL InjuryACL - Anterior Cruciate Ligament Rupture2 more

The overall objective of this study is to conduct a two-group randomized trial to examine the efficacy of cognitive-behavioral based physical therapy (CBPT) for improving knee function, return to sport, and quality of life outcomes in patients following ACL reconstruction (ACLR). The study consists of two treatment groups: telephone-based cognitive-behavioral based physical therapy for ACLR (CBPT-ACLR) and telephone-based Education. The central hypothesis is that the CBPT-ACLR participants relative to the Education group will demonstrate significantly greater improvement in postoperative outcomes at 12 months following surgery.

Arthroscopic ACL Reconstruction: Hamstring Versus Quadriceps

Anterior Cruciate Ligament InjuryAnterior Cruciate Ligament Rupture

The use of hamstrings and quadriceps autografts as an alternative option for reconstruction of the anterior cruciate ligament has good clinical results: however, both techniques have not been compared among them, which is why this study is intended. The use of quadriceps tendon autograft in anterior cruciate ligament repair presents similar or better results compared to autograft of the hamstrings. The objective of the study is to compare the clinical effectiveness of anterior cruciate ligament reconstruction between the use of quadriceps tendon autograft versus hamstring autograft.

Anterior Cruciate Ligament InjuriesLigament; Rupture4 more

The use of implants for conventional anterior cruciate ligament (ACL) graft fixation has been associated with several problems including graft injury, implant osteolysis, implant migration and soft tissue irritation. Implantless ACL surgery offers additional benefits involving lower cost, improved graft incorporation and ease of revision surgery. The investigators aimed to compare the functional outcome of implantless bone-patellar tendon autograft using press-fit fixation technique and hamstring autografts using implant.

Factors Affecting the Speed of Recovery After ACL Reconstruction

Anterior Cruciate Ligament InjuryACL Injury1 more

The purpose of this study is to find out how postoperative pain affects recovery after anterior cruciate ligament (ACL) repair. Complete recovery after ACL repair involves healing of tissues at the surgical site, but also recovery of strength of the muscles that control movements at the knee. Some pain is normally experienced after ACL repair; the severity is variable from one individual to another. Pain is usually controlled by intravenous and oral (by mouth) pain medicines. It is also frequently controlled by numbing nerves that supply sensation to the knee joint and surrounding tissues. This procedure is called a nerve block. The investigators want to determine if standard methods of pain control after surgery affect future pain control, and the ability to exercise and recover muscle strength after surgery. The investigators are also interested in determining what other factors, such as age, gender, anxiety, or coping skills might be predictive of pain severity and speed of recovery. As part of the study, the investigators will record subject's ratings of pain severity, use of painkiller medicines, and muscle bulk measured by standardized tests, at various time intervals in the first 6 months after surgery. The investigators will also ask them to complete two questionnaires,one that enquires about subject's responses to pain in the past (catastrophizing test), and one that measures anxiety they might have about surgery or pain on the day of surgery. The investigators will be studying approximately 180 people who are having ACL repair at University of Washington. Subjects may be involved who are having multiple ligaments repaired including the anterior cruciate ligament

Electrical Stimulation and Eccentric Exercise for Anterior Cruciate Ligament (ACL) Injury

Anterior Cruciate Ligament Injury

Quadriceps muscle weakness is a common consequence of ACL injury. This muscle weakness is considered to result from neural inhibition preventing full muscle contraction and is referred to as arthrogenic muscle inhibition (AMI). AMI hinders rehabilitation by preventing gains in strength, increasing the risk of re-injury, and potentially placing patients at risk for chronic degenerative joint conditions. Quadriceps weakness that occurs following ACL injury is also thought to be caused by muscle atrophy which is thought to manifest due to alterations in muscle architecture, selective fiber atrophy or even neural deficits such as AMI. Importantly, interventions that are designed to counter this muscle weakness are required in order to promote long-term knee joint health. Hence, the purpose of the current study is to determine the efficacy of interventions that target quadriceps weakness to improve quadriceps muscle function and biomechanics in patients prior to and following ACL reconstruction. Specifically, the efficacy of neuromuscular electrical stimulation aimed at improving quadriceps neural activity and eccentric exercise intended to minimize quadriceps muscle atrophy will be investigated. The investigators expect that patients who receive the electrical stimulation therapy will demonstrate improvements in quadriceps strength and activation. Furthermore, it is expected that patients who receive both the electrical stimulation and eccentric intervention will demonstrate markedly greater gains in quadriceps strength and activation than patients who receive only the electrical stimulation therapy or standard of care post-surgery. The investigators also hypothesize that the patients who receive the electrical stimulation therapy and/or eccentrics will display knee motion similar to uninjured control subjects.

Prospective Femoral Versus Femoral and Sciatic Nerve Block for Anterior Cruciate Ligament (ACL)...

Anterior Cruciate Ligament Tear

The investigators propose that a preoperative femoral and sciatic blocks vs a femoral block only, prior to ambulatory anterior cruciate ligament (ACL) reconstruction will lead to a decrease in opiate consumption, pain scores, and post-anesthesia care unit (PACU) length of stay. The investigators are prospectively randomizing patients to either a femoral or a fem/sciatic block and monitor outcomes.
