Active clinical trials for "Anterior Cruciate Ligament Injuries"

A comparison of two anesthetic techniques-- the Adductor Canal Block (ACB) and the Adductor Canal Block with Infiltration of the interspace between the popliteal artery and the capsule of the posterior knee (ACB/IPACK)-- in patients undergoing bone-tendon-bone (BTB) anterior cruciate ligament (ACL) reconstruction.

The aim of this pilot study is to understand the biological changes that occur within the knee joint following injury to the anterior cruciate ligament (ACL). This will be achieved through aspiration and analysis of the haemarthrosis which fills the knee following injury. The study will look at inflammatory and healing responses using DNA, RNA and protein analysis. This, combined with high resolution imaging of the knee and surrounding soft tissue structures, may enable a more patient specific approach to treatment of ACL injury.

Study population The investigator set the sample size to 200 patients. Primary outcome Diagnostic accuracy of ultrahigh field MRI (T7) compared to high field MRI (T3 or less) for detection of meniscal injuries associated with acute ACL injury Secondary outcome Influence of 1) Location of injury and 2) meniscal tear pattern (modified WORMS18,19) on the sensitivity of high field MRI compared to ultrahigh field MRI for detection of meniscal tears

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).

Knee injuries, especially those to the ACL, are common among physically active people. Preventing these injuries from happening is critical to limiting the long-term pain, disability, and arthritis associated with these injuries. Our study is going to examine new ways to provide feedback about the way people move to determine if these are better at modifying movement patterns to prevent injury than current standard treatments. If you participate, you will be asked to undergo a movement analysis in a research laboratory while you perform tasks such as landing from a box and running and cutting. After this initial assessment, you will be randomly allocated to one of 3 treatment groups. Each treatment group will perform 4 weeks (3x/week) of exercises to change the way people land from a jump. Participants will then report for follow-up movement analysis testing 1- and 4-weeks after completing the intervention.

The objective of this study is to answer the following questions: Does the appearance of the reconstructed anterior cruciate ligament (ACL) vary in appearance on PET/MRI depending on graft type and time after surgery? What is the appearance of the native ACL on Positron Emission Tomography/Magnetic Resonance Imaging (PET/MRI)?

The aim of the study is to examine the influence of number of the harvested hamstring tendons on subjective and objective outcomes of primary anterior cruciate ligament reconstruction.

Currently, most patients with an anterior cruciate ligament (ACL) injury undergo surgery. There is a general belief that surgical reconstruction is necessary to return to sport safely and to limit premature knee osteoarthrosis or additional meniscal damage. However, there is unsufficient scientific evidence for this belief. Moreover, several studies show that a reconstruction does not guarantee successful return to sports or the prevention of osteoarthritis or meniscal injuries at all. Therefore, an immediate surgery after an ACL injury is more and more questioned. The only qualitative RCT that exists (KANON trial) could not demonstrate that an immediate reconstruction is an added value (in terms of symptoms, knee function, activity level, osteoarthritis or incidental meniscal damage) compared to a conservative approach consisting of progressive rehabilitation and delayed surgery if there was persistent knee instability. In a future multicenter RCT the investigators want to 1) verify these results and 2) search for predictors that predict which patients from the conservative group do well without delayed surgery. This information is invaluable to physicians as it allows them to decide which treatment is best for the patient. Before performing a large, adequately-powered RCT that compares both treatment options, the investigators will run a pilot study that assesses the feasibility to recruit ACL patients for such RCT. This seems necessary, as many patients still believe that timely surgery is a prerequisite for restoring knee function, for returning to sports and for preventing cartilage degeneration. These preferences for surgery might affect recruitment and adherence to the protocol. Therefore, a pilot study will performed that demonstrates whether a large RCT is feasible with regard to 1) participant recruitment, 2) adherence to the treatment arm they were allocated to and 3) protocol feasibility. The findings of this pilot study will help deciding about progressing to a future definitive RCT.

The purpose of this study is to evaluate subjective and objective clinical outcomes and imaging data of subjects undergoing reconstruction or revision of LCA reconstruction using OrthoPure XT
