Active clinical trials for "Rupture"

The objective of this clinical investigation is to evaluate, in a controlled setting, the safety and performance of the BeGraft Peripheral (BGP) balloon expandable covered stent Graft System (Bentley InnoMed, Hechingen, Germany) implanted as bridging stent in FEVAR (fenestrated endovascular aortic repair) for complex aortic aneurysms.

The purpose of this trial is to investigate the efficacy of standard care versus standard care combined with an early progressive exercise program in improving the function of the tendon and leg muscles after non-surgical treated Achilles tendon rupture

The objective of this clinical investigation is to evaluate, in a controlled setting, the safety and performance of the BGP+ balloon expandable covered stent Graft System (Bentley InnoMed, Hechingen, Germany) implanted as bridging stent in BEVAR (branched endovascular aortic repair) for complex aortic aneurysms.

Early rehabilitation protocols have been studied in Achilles tendon (AT) rupture patients, but deficits in tendon biomechanical properties have been observed several years after the injury. AT rupture patients are unable to return to their previous levels of physical activity. They present deleterious adaptations in the plantar flexor muscles that lead to functional deficits, and deficits in the tendon's structural and mechanical properties. Eccentric contractions have been suggested to recover these muscle properties. This contraction is known to produce higher force compared to isometric and concentric contractions, and increases tendon stiffness. However, there is a lack of studies showing the effects of the eccentric training in AT rupture rehabilitation. We want to know if an isokinetic eccentric training program will determine the desired adaptations on triceps surae muscle-tendon unit's properties in patients subjected to the AT surgical repair. More specifically, the aim of this study is verifying the effects of a 12-week eccentric training program on triceps surae muscle-tendon unit's properties in subjects that were subjected to the AT surgical repair. 30 subjects will be randomized in two groups: (1) isokinetic eccentric training; and (2) traditional eccentric training control group. All participants will be submitted to a four-week control period, followed by a 12-week period of training for the plantar flexor muscles. Neuromuscular system properties, AT biomechanical properties and functional tests will be evaluated. Participants will be evaluated in four moments: at baseline; after 4, 8 and 12 weeks of rehabilitation. Tendon mechanical (stiffness, stress, strain), material (Young's modulus) and morphological (cross-sectional area and tendon length) properties; muscle architecture (thickness, pennation angle and fascicle length); and functional tests (heel rise resistance and height) will be analyzed between groups and periods. Effects and interactions will be analyzed with ANOVA two-way. Clinical effects will be analyzed using effect size and magnitude-based inferences.

The anterior cruciate ligament (ACL) is one of four strong ligaments connecting the bones of the knee joint. If overstretched, the ACL can tear. Reconstruction of a torn ACL is now a common surgical procedure. The amount of tension applied to the ACL during reconstruction may indirectly affect the possible onset of arthritis over time. The purpose of this study is to determine the effect of initial graft tension set during ACL reconstruction surgery on the progression of knee arthritis over at least a 15-year period.

The main purpose of this study is to determine if there is a difference in graft re-injury/failure rates between participants that have had an ACL reconstruction with a STG, BPTB or QT autograft. Additionally, to compare quality of life, patient reported outcomes and functional performance after ACL reconstruction with STG, BPTB and QT.

Patients with acute achilles tendon rupture will go through an acute ultrasound. Based on the distance between the ends of the tendon the investigators will decide if the patient is going to be treated with or without surgery.

Anterior cruciate ligament (ACL) tears are diagnosed by combining the patient's history and physical examination but clinical tests (e.g., Lachman, anterior drawer, and pivot shift) are less accurate within the first three weeks of injury. The Lever sign is a clinical test that has shown to have comparable diagnostic accuracy regardless of the time since injury, but this test has not been subjected to a randomised clinical trial and diagnostic values may be overestimated. Imaging modalities (e.g., MRI) are utilised when clinical diagnosis is not clear but are expensive and delay diagnosis. Hand-held arthrometry is an instrument that can be used in the clinical setting to provide an immediate, objective measure of ACL laxity, but this device has not been adequately validated. The first aim of this study is to determine the accuracy of hand-held arthrometry for diagnosing ACL tears following acute injury. A reliable and valid device could reduce healthcare costs and expedite appropriate treatment, thereby improving the management of patients following knee injury. The second aim of this study is to determine the diagnostic accuracy of the Lever sign test using a more robust study design than previously employed in other studies.

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).

The investigators will be evaluating the use of versawrap in the setting of distal radius fractures by placing membrane between plate and flexor tendons. Investigators will then evaluate tendon gliding morphology and number of tendon ruptures
