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 use better magnetic resonance imaging (MRI) techniques to examine the knee and the bony and soft tissue changes so as to better predict the progression of osteoarthritis and acute knee injuries.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will examine the pathophysiology of bone marrow changes, relationship between trabecular bone and cartilage changes; and evaluate T1p relaxation methods and its' relating to cartilage loss. The protocol is geared towards sequences utilizing 3 Tesla magnetic resonance imaging (MRI) that will enable the measures of cartilage volume and T2. Measures cartilage volume and T2 are more established MR methods for studying osteoarthritis (OA).

All OA and Anterior cruciate ligament (ACL) subjects will undergo MR imaging of the knee joint at 3 Tesla at baseline,, and three annual follow up time points. Regions of interest will include the total tibial and femoral cartilage, and sub-division such as the medial and lateral compartments of the tibial and femoral cartilage to account for localized disease activity and progression.

Bone marrow edema size, MR spectroscopy based marrow fat/water content, and trabecular bone microarchitecture underlying the edema will be measured in the OA and ACL groups to determine whether there is any distinction between these measures in OA and in traumatic ACL injury, cross-sectionally and longitudinally, and their relation to cartilage loss and OA progression.

Eligibility Criteria

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

Inclusion Criteria

* Healthy volunteers will have had no previous knee symptoms or surgery
