Ever wonder how the way you walk may affect your knees? Have you ever had an ACL reconstruction? You may be able to take part in a study to learn more about how different types of force applied to your legs can affect your knee while walking on a treadmill.

Have you recently had an anterior cruciate ligament injury and will be undergoing anterior cruciate ligament reconstruction surgery? If so, you may be able to participate in a study comparing the effects on pain relief and arthritis prevention of metformin or placebo. Compensation provided.

We are conducting a research study to use graded exposure and mobile mindfulness meditation to address clinical outcomes in individuals 6-months to 10-years post-ACLR. This will help develop effective treatments to improve outcomes after ACLR. This study will last 5 weeks. Compensation provided.

Have you had ACL reconstruction in the past 9 months to 10 years? You may be able to take part in a research study to help us learn more about how the type of shoes you wear influences your walking mechanics.

Do you have a history of ACL reconstruction? You may be eligible to participate in a study using virtual reality and mindfulness meditation! We aim to explore psychological factors that may impact return to play outcomes after ACL reconstruction.

The purpose of this project is to quantitatively and qualitatively examine the adherence and acceptability of the Oura Ring, and to examine the accuracy of the Oura Ring to measure physical activity. *This study is a collaboration with the UNC Sports Medicine Institute*

Interested in participating in future research studies? Whether you have had a previous ACL injury or not, you may be able to take part in several research study opportunities. This registry simply collects your contact information and then we will reach out if any study opportunities are available.

Are you interested in participating in orthopedic research? Are you otherwise healthy, with no previous history of lower extremity orthopedic injury? If so, you may be able to participate in a research study to determine the gait patterns of an otherwise healthy population.

Up to 30% of individuals who injure their anterior cruciate ligaments (ACL) suffer another ACL injury following reconstruction surgery. Improving function of the hamstrings muscles may reduce the risk of a second ACL injury. This study will determine if a novel rehabilitation tool (local muscle vibration) improves muscle function and landing characteristics (biomechanics) that are linked to ACL injury risk. Compensation is provided.

Have you had ACL reconstruction? You may be able to participate in a research study examining how brain function might change after surgery. Compensation provided.
