To date, the use of the quadriceps tendon as an autograft option in primary paediatric Anterior Cruciate Ligament (ACL) reconstruction has not been well studied. The 2018 International Olympic Committee (IOC) Consensus Statement now outlines the quadriceps tendon as a possible autograft option. However, no Randomised Control Trial (RCT) has examined the efficacy of the quadriceps tendon autograft in primary paediatric ACL reconstruction compared to the historical "gold-standard" soft-tissue hamstring autograft in this population. In light of its evidence for favourable outcomes in the adult population, and the (albeit limited) evidence showing safety and promise in the paediatric population, clinical equipoise exists for assessing its impact on outcomes in paediatric patients at the index surgery. This trial aims to demonstrate feasibility of a global RCT that will evaluate the efficacy of soft-tissue quadriceps versus hamstring autograft tendons on re-operation, return to sport, and knee function among paediatric patients undergoing primary ACL reconstruction.
The purpose of our study was to compare osseous integration of the bone block in Achilles tendon allograft ACL reconstruction using a cortical button versus biocomposite interference screw fixation. The primary outcome was bone block incorporation within the femoral tunnel at six months. Our null hypothesis was that there is no difference in osseous incorporation or outcome with either type of femoral fixation in primary ACL reconstruction with Achilles tendon allograft. Our secondary outcomes were pain and clinical outcome scores between the two groups.
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
The purpose of this study is to evaluate the effect of the Össur Rebound dynamic ACL brace on knee kinematics evaluated using dynamic stereo X-ray (DSX) imaging during functional activities. Brace performance will be evaluated before and after ACL reconstruction.
The proposed study will establish novel relationships between intra-articular mesenchymal stem cell (MSC) recruitment, synovial inflammation, biomarkers of cartilage degeneration and joint inflammation, clinical patient factors, and downstream alterations in cartilage composition and morphology to provide novel insights into the pathoetiology of post-traumatic osteoarthritis (PTOA) after ACL injury and reconstruction. The study aims to enroll N=38 total patients with primary, isolated rupture to their anterior cruciate ligament (ACL), who have agreed to participate in the study and who will undergo primary surgical reconstruction by an orthopaedic physician at our two sites. Patients will undergo baseline magnetic resonance imaging (MRI), baseline clinical evaluation, and undergo a baseline blood draw. Subsequent imaging and clinical evaluations will be longitudinally performed at several postoperative timepoints up to 12 months postoperatively.
Primary objective of the study is to evaluate efficacy of the surgical technique for ACL reconstruction using an osteoconductive scaffold, enlaced into the hamstring tendon autograft, compared to the traditional technique.
The purpose of this single-center, double-blinded randomized control trial with prospective data collection is to assess the ability of platelet rich plasma (PRP) treatment to reduce the level of pro-inflammatory synovial fluid biomarkers following an acute anterior cruciate ligament (ACL) tear. The study will collect and analyze synovial fluid of patients presenting with an acute anterior cruciate ligament (ACL) tear with a second synovial fluid sampling at the time of surgery. It will compare synovial fluid biomarker levels between those receiving an intra-articular Platelet Rich Plasma (PRP) injection versus an intra-articular saline injection serving as a control. Post-operative clinical outcomes will also be assessed, including post-operative pain levels, incidence of post-operative knee stiffness and patient reported outcome scores.
After anterior cruciate ligament (ACL) injury, the involved quadriceps may demonstrate weakness due to decrease in quadriceps activation. However, elapsed time from the injury may affect muscle strength by restoration of the quadriceps activation. The injury is characterized by joint instability that leads to decreased activity, unsatisfactory knee function, and poor knee-related quality of life in the short term, and it is associated with an increased risk of osteoarthritis on the knee. This study was designed to compare muscle strength, questionnaire and knee function in patients with different exercise training.
Collagen based -membrane derived from amniotic tissue can be used to help reestablish the natural synovial lining of the reconstructed ACL, in effect acting as both a barrier from the synovial fluid and as a scaffold to contain autologous mesenchymal stem cells and growth factors contiguous with the graft, thus aiding and perhaps accelerating the natural maturation and ligamentization process of the implanted graft tissue. Acceleration and improvement in graft maturation and strength would be a significant advancement in sports medicine allowing safer and earlier return to sports and activity
The objective of this study is to evaluate the use of wrapping an ACL graft with a collagen matrix tissue wrap and injecting autologous bone marrow aspirate concentrate under the wrapping and into the graft. Investigators hypothesize that this method of augmenting ACL surgery will accelerate and improve the graft maturation and ligamentization process. Investigators propose to test this hypothesis with a series of cases of ACL reconstructions evaluated with post-operative MRI mapping sequences and validated clinical outcome measures
