Purpose

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.

Biospecimen Retention: Samples Without DNA

Biospecimen Description:

Bone/cartilage tissue will be collected after the total knee replacement surgery. The tissue will further studied using advanced MR imaging techniques.

Estimated Enrollment:	145
Study Start Date:	August 2006
Estimated Study Completion Date:	December 2012

Groups/Cohorts	Assigned Interventions
1 Healthy volunteers without knee pain.
2 Patients with mild arthritic symptoms and radiographic changes (Kellgren Lawrence score of 1, 2)
3 Patients with severe pain and functional limitations associated with knee arthritis (Kellgren Lawrence score of 3, 4).	Procedure: Total Knee Replacement
4 Patients with acute anterior cruciate ligament (ACL) injuries with associated osseous contusion.	Procedure: ACL Reconstruction Surgery
5 Patients with posttraumatic knee injury or degenerative condition and will have cartilage resurfacing procedures.	Procedure: Cartilage Resurfacing Surgery

Detailed Description:

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.

Criteria

Inclusion Criteria:

Healthy volunteers will have had no previous knee symptoms or surgery
Patients with mild arthritic symptoms and Kellgren Lawrence score of 2
Patients with severe arthritic symptoms and Kellgren Lawrence score of 3, or 4
Patients with acute ACL injury with associated bone contusion and bone edema
