Filter by:Currently the diagnosis of OA is based on radiographs and clinical findings, which is limited to detecting late-stage disease. There is a pressing, unmet clinical need for robust assessment of early changes in cartilage health. Towards this goal, extensive efforts are ongoing to develop quantitative MRI for cartilage matrix analysis. MR T1ρ and T2 relaxation times have shown to be promising imaging biomarkers for early cartilage degeneration and prediction of disease progression. However, many challenges remain to clinically applying these techniques, including lack of standardized acquisition and quantification methods, and long acquisition times. The study aims to develop novel, fast and reproducible MR T1ρ and T2 relaxation time imaging methods on MR systems from multiple vendors and establish a platform for standardization and cross validation of these measures as a tool for clinical trials using such techniques. Following method validation, patients at risk for osteoarthritis will be tested.
The study is a prospective randomized control trial consisting of subjects requiring ACL reconstruction with BTB autograft. Subjects were randomly divided into two groups following their inclusion in the study. One group underwent the normal ACL rehab protocol as determined by the participating surgeons. The study group underwent normal ACL rehab modified by use of a tourniquet for blood flow restriction during selected exercises.
This study will evaluate the efficacy of the Graymont X ERIS Knee Splint brace in the postoperative period of ACL reconstruction to improve range of motion, specifically the achievement of terminal extension and time-to-achievement compared to the standard hinged knee brace. This will be directly measured with goniometric angle and heel-height measurements relative to the contralateral side. Other metrics will include standard, validated patient reported outcomes and requirements for additional interventions to treat extension deficits including, but not limited to, additional therapy, intraarticular injections, oral corticosteroids, manipulation under anesthesia, or arthroscopic arthrolysis.
While there are a number studies that have reported on the use of BFR in the adult population, there is limited information about the use of BFR in the adolescent population. This study aims to evaluate the use of BFR training in conjunction with traditional ACL (anterior cruciate ligament) reconstruction rehabilitation in adolescents. The purpose of this study is to evaluate the addition of BFR-based exercise to traditional methods of physical therapy. Does the use of BFR-based exercise improve strength, hypertrophy, functional and patient reported outcomes after ACL Reconstruction in the adolescent population?
A prospective study, with outcomes including re-rupture rate and return to sport will be collected following ACL reconstruction. In keeping with the surgeon's standard practice, patients 24 years and under that are skeletally mature, will receive a quad tendon autograft; patients 25 years of age and over will receive an allograft All-Inside ACL reconstruction. These two cohorts will then be randomized into two groups, one with bone marrow/DBM and InternalBrace augmentation, and one without. The study procedures will involve use of x-rays, MRI, CT scan, and surveys at varying time points to assess radiographic, imaging and clinical outcomes.
Postoperative protocols for orthopedic procedures on the lower limb often require a period of immobilization to protect the surgical site. The consequence of this immobilization is muscle atrophy which can be severe, delaying a patient's return to activity and predisposing them to recovery complications or subsequent injury (1)(2). The current standard methods to assess lower limb muscle atrophy all have their respective limitations. Thigh circumference or isokinetic strength values are indirect measures of atrophy and can be inaccurate. Magnetic resonance imaging (MRI) of muscle cross-sectional area (CSA) is time-consuming and expensive. Computed tomography imaging of muscle CSA is expensive and exposes the patient to radiation (3). For these reasons, none of the current methods are ideal for regular use in the clinic. Musculoskeletal ultrasound is a promising measurement tool to assess muscle atrophy in postoperative patients. Ultrasound is non-invasive, cost-effective, does not involve radiation, and can give direct images of muscle size (4). Musculoskeletal ultrasound requires further research on its potential as an evaluation tool for postoperative lower limb orthopedic patients-specifically, whether ultrasound is a reliable and valid tool for quadriceps size measurements.
This prospectively study aims to evaluate the evolution of knee joint proprioception on isokinetic dynamometer before and after Anterior Cruciate Ligament (ACL) reconstruction and its relationships with muscle strength, self reported questionnaire and return to sport. This study will include 30 athletes with isolated ACL rupture, and treated with ACL reconstruction surgery and 15 healthy volunteers.
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.
The purpose of this study is to examine the long-term appearance and resorption rate of biocomposite screws used during ACL reconstruction on X-ray and computed tomography (CT).
