Below are current clinical trials.

Filter this list of studies by location, status and more.

1. A Study of Clinical Outcomes of Ultrasound-guided Carpal Tunnel Release Performed in a Procedural Room Setting

   Albert Lea, Minn.

   The purpose of this study is to document the primary investigator’s clinical experience performing Ultrasound Guided Carpal Tunnel Release (USCTR) in the clinic procedure room setting through retrospective and prospective analysis of these now routinely collected clinical outcomes. 

2. A Study to Evaluate Preventative Saphenous Nerve Neurectomy in Primary Total Knee Arthroplasty

   Jacksonville, Fla.

   The purpose of this study is to evaluate the incidence of chronic knee pain at 6 months following primary total knee arthroplasty. Secondary outcomes include incidence of knee numbness, postoperative sensory loss or change at the knee, range of motion (ROM), resting pain with Visual Analog Scale (VAS), Knee Injury and Osteoarthritis Outcome Score (KOOS), quality of life measurement assessed by SF-36.

3. A Study to Evaluate Outcomes of Pectoralis Minor and Brachial Plexus Release

   Rochester, Minn.

   The purpose of this study is to to assess the clinical and radiographic outcomes of patients who have undergone shoulder arthroplasty.

4. A Study to Create a Registry of Non-Fusion Spinal Deformity Correction in Adolescent Idiopathic Scoliosis

   Rochester, Minn., Minneapolis, Minn.

   The primary purpose of this study is to evaluate the effectiveness of non-fusion surgical treatment of Spinal Deformity Correction in Adolescent Idiopathic Scoliosis.

   The Post Approval Study (PAS) is gathering data on the Tether device and it's efficacy and safety.

5. Early Outcomes of Volar Capsulodesis for the Treatment of Scapholunate Ligament Injury

   Rochester, Minn.

   The purpose of this study is to:

   1. To provide a comprehensive review of Mayo Clinic’s experience with volar SLIL capsulodesis
   2. Investigate the relationships between patient risk factors and clinical variables with functional outcomes and patient satisfaction
   3. Determine rates of complication, revision surgeries and salvage for failure

6. Knee Biologic Preservation: Functional and Clinical Outcome

   Rochester, Minn.

   The main purpose of this study is to evaluate the clinical and functional outcomes of patients undergoing biologic knee preservation surgery. Secondary purpose is to identify possible correlation between outcome and pre-operative radiological findings (i.e. bony abnormalities such as mal-alignment, size of cartilage defect).

7. Genetic Expression in Osteolysis, Infection, Arthrofibrosis & Metal Reactions in THA & TKA: A Microarray Analysis to Characterize Individual Host Response to the Molecular Mechanisms of Loosening and Arthrofibrosis

   Rochester, Minn.

   This study is being conducted to determine gene and protein expression profiles (i.e. which genes and proteins are turned off and on) of those with a possibility of developing osteolysis, infection, arthrofibrosis or metallosis of their THA/TKA.

8. A Study to Evaluate Awake vs. Asleep Spine Surgery

   Jacksonville, Fla.

   Patients undergoing spine lumbar surgery will be asked to perform short exams/questionnaires aimed at determining cognitive function, quality of life, health outcomes twice post surgery with a baseline performance prior to surgery.

9. A Study to Validate the Patient-Specific Functional Survey in Patients with Carpal Tunnel Syndrome

   Rochester, Minn.

   The purpose of this study is to determine if the Patient-Specific Functional Survey (PSFS) is a valid and reliable measure to evaluate functional difficulties with carpal tunnel syndrome.

10. 3D US Imaging of Acute Nerve Root Avulsions in Injuries of the Brachial Plexus

    Jacksonville, Fla.

    The purpose of this study is to address a knowledge gap. Early diagnosis of nerve root avulsion injuries following brachial plexus trauma remain a barrier to the early treatment of these complex injuries.  Traditionally, an observation period of 6 months following brachial plexus injuries has been utilized to allow for reinnervation.  Reinnervation is not possible in the setting of nerve root avulsion from the spinal cord and waiting for reinnervation in this setting unnecessarily delays treatment and potentially compromises outcome.  Having the ability to provide a real time evaluation of nerve root integrity would obviate the need of other more expensive and complex advanced imaging such as CT/myelography, currently considered the good standard.
