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

1. A Study of Performance of a New Investigational Prosthesis Design and Explore How Mimicking the Human Ankle May Enhance Maneuverability of Walking

   Rochester, Minn.

   The purpose of this study is to see how you walk with an investigational new type of ankle-foot prosthesis that has been developed, which can allow motion in more than one direction.

2. Anterior Vertebral Body Tethering (AVBT) Using Dynesys System Components to Treat Pediatric Scoliosis

   Rochester, Minn.

   The Researchers want to assess the short-term safety of Anterior Vertebral Body Tethering (AVBT) in skeletally immature subjects with moderate to severe scoliosis.

3. Hamstring Strain in High School Athletes

   Minneapolis, Minn., Rochester, Minn.

   The purpose of the current study is, 1) Determine the effectiveness of injury prevention programs for prevention of hamstring muscle strains, 2) Identify how these programs impact athletes' flexibility, muscle stiffness, strength, and power, and 3) Determine the ability of a state-of-the-art imaging technology, shear wave elastography to predict future hamstring muscle strain injury.

4. A Study to Evaluate the Incidence of Infrapatellar Branch of the Saphenous Nerve Encounters during Knee Arthroplasty

   Jacksonville, Fla.

   The aim of this study is to evaluate the incidence of infrapatellar branch of the saphenous nerve encounters during the standard medial parapatellar approach to the knee during arthroplasty.

5. Direct Anterior vs. Anterolateral Approach for Hip Arthroplasty After Femoral Neck Fracture in the Senior Population

   Rochester, Minn.

   Displaced femoral neck fractures are one group of hip fracture patients that are commonly treated with cemented hemiarthroplasty (HA) or total hip arthroplasty (THA). In the elective hip arthroplasty population, the direct anterior approach (DAA) has shown to be effective in helping patients to quickly obtain high postoperative function. This approach has also been shown to be effective in arthroplasty for displaced femoral neck fractures in a few studies. However, the only studies that directly compare two approaches for hip arthroplasty for femoral neck fractures utilize the anterolateral approach (ALA) versus posterior approach (PA) or DAA versus PA. No studies of which we are aware directly compare the DAA to the ALA. The DAA and ALA are the two most popular approaches for bipolar hemiarthroplasty at our institution, so we are setting out to determine the differences between them.

6. A Study to Compare Bone Ultrasound to Xrays for the Evaluation of Forearm and Clavicle Fracture Healing

   Rochester, Minn.

   The purpose of this study is to compare the use of ultrasound to traditional xrays to evaluate fracture healing over time in patients with radius/ulna (arm) fractures.

7. Sex Disparities in Arthrogenic Muscle Inhibition Following ACL Injury

   Rochester, Minn.

   Incidence of anterior cruciate ligament (ACL) ruptures disproportionately affect female athletes at a rate 4-6 times greater than male counterparts. In addition, females have a reinjury rate 16 times that of healthy female controls and 4 times that of male ACL reconstruction (ACLR) counterparts. After ACL injury and throughout rehabilitation, a ubiquitous impairment that limits athlete progression to return to sport (RTS) is atrophy of the musculature surrounding the knee, termed arthrogenic muscle inhibition (AMI).The focus of the study is to develop an objective, reproducible, and reliable measure of neuromotor activation (directly correlated with AMI) and neuromuscular elicited muscle stiffness for both injury prevention and rehabilitation.

8. Scoliosis Shared Decision Making

   Rochester, Minn.

   Analysis of video encounters between providers, patients, and families will be used to develop a shared decision making tool for patients deciding between surgery and observation for scoliosis treatment.

9. Survey of Preferences Regarding Spinal Implants

   Rochester, Minn.

   The purpose of this study is to evaluate patient and parent willingness to participate in a proposed randomized controlled trial evaluating a low vs. high implant density for surgical treatment of scoliosis.

10. RCT Comparing Robotically-Assisted vs. Manually-Executed Total Knee Arthroplasties

    Rochester, Minn., Scottsdale/Phoenix, Ariz.

    This study will explore if there are any difference in functional outcomes between two different surgical procedures for total knee replacement: robot-assisted versus manually-executed total knee arthroplasty.
