Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the effect of the Össur Rebound dynamic ACL brace on knee kinematics evaluated using dynamic stereo X-ray (DSX) imaging during functional activities. Brace performance will be evaluated before and after ACL reconstruction.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NA

Intervention Model

SINGLE_GROUP

Evaluation of knee stability with brace wear. Control is same subject without the brace.
Primary Study Purpose

BASIC_SCIENCE

Blinding Strategy

NONE

Investigators and participants cannot be blinded as to whether or not the brace is worn.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Knee Brace

ACL-reconstruction patients will be issued an Ossur Rebound ACL Brace at the time of enrollment in the study, prior to surgery. They will use this brace throughout their rehab and physical therapy.

Dynamic X-ray imaging of the knee will take place prior to surgery, and again upon clearance from physical therapy 7-9 months after surgery. The injured knee will be imaged with and without the brace, and the contralateral limb will be imaged for use as a control.

Group Type EXPERIMENTAL

Ossur Rebound ACL Brace

Intervention Type DEVICE

ACL-reconstruction patients will be issued an Ossur Rebound ACL Brace at the time of enrollment in the study, prior to surgery. They will use this brace throughout their rehab and physical therapy. The intervention (brace) will be applied only to the surgical limb.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Unilateral, complete ACL (Anterior Cruciate Ligament) ruptures (must be documented by prior MRI)
* No other concomitant lower extremity injuries and an uninjured contralateral limb
* Acute ACL tears that will be scheduled for ACL reconstruction with Dr. Robert F. LaPrade
* Minimal swelling and pain
* Able and willing to perform the required study activities

Exclusion Criteria

* Previous surgery or significant injury to either knee
* Relevant surgery, procedure, injury, or condition in the past two years which may affect knee pain or general movement patterns on either side
* Diagnosis of osteoarthritis, rheumatoid conditions, cancers, or other conditions which may affect musculoskeletal health
* Women who are pregnant, or trying/planning to become pregnant during the next 10 months
* Known balance or vestibular disorders
* Persons with a history of significant radiation exposure, whether occupational or medical in nature (Anyone with a history of medical radiation therapy, for cancer or other conditions, is excluded from the study. Those who have an annual occupational radiation exposure greater than 25mSv may not enroll.)
* Persons with a pacemaker, hearing aid, aneurysm clip or artificial heart valve, or other forms of loose metal implants
* Allergy or sensitivity to silver or latex
* Adults lacking capacity to consent for themselves


* Participants who do not pass their return-to-sport test within 7-9 months of ACL-Reconstruction surgery will be excluded from the second phase of testing.
* Participants who no longer pass the MRI screening at the time of Phase 2 testing (for example, who have a new loose metal implant), will be excluded from the MRI portion of the testing only.
