Standing Computed Tomography (SCT) Imaging of the Knee Joint

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03446404

Brief Summary:
This study will help us decide the best way to image the knee for diagnostic purposes: Knee computed tomography vs knee x-ray. The computed tomography will provide a weight bearing 3D view.

Condition or disease Intervention/treatment Phase
Osteoarthritis, Knee Diagnostic Test: Standing Computed Tomography Not Applicable

Detailed Description:
This will be an ancillary study to the Multicenter Osteoarthritis Study (MOST) second renewal #201511711). Using a prototype Curve Beam Standing Computed Tomography (SCT) scanner to get a 3 dimensional picture of the knee joint, bilaterally. This scanner by Curve Beam 175 Titus Ave, Suite 300, Warrington, Pennsylvania 18976, has been approved by the Food and Drug Administration (FDA) for ankles and feet. This has been modified to do the scan of the knee but is not yet approved by the FDA for the knees. The proposed ancillary study would add the key benefit of providing more sensitive and accurate identification of prevalent knee osteoarthritis (OA) at baseline and incident knee OA at follow-up than is available with plain radiographs. In addition, it would enable biomechanical modeling of the knee joint on a larger scale than achieved in any prior study, allowing testing of biomechanical hypotheses regarding mechanisms of disease development and progression that have not been possible on this scale previously.

Arm Intervention/treatment
MOST Cohort
One portion of the cohort will be age 62-92 years, average age approximately 71 years, at the start of this study. This cohort will consist of participants who already have symptomatic knee OA, in many cases advanced disease, or who had risk factors at the start of the Multicenter Osteoarthritis Study but have not developed symptomatic knee OA. All of the existing cohort who have 1 or 2 "native" knees will be approached providing native knees are not considered to be Kellgren-Lawrence grade 4 (bone on bone). The other portion of the cohort will consist of subjects with knee pain, aching or stiffness at baseline and participants without any knee symptoms in the previous 30 days. Both knees with Kellgren-Lawrence grades of radiographic OA of 0, 1, or 2 in the tibiofemoral (TF) and patellofemoral (PF) compartments.
Diagnostic Test: Standing Computed Tomography
Provides weight bearing 3D view of knees.
Other Name: SCT

Primary Outcome Measures :
  1. Change in Joint Space Width [ Time Frame: Baseline and 2-years ]
    3D measurement of distance between articular surfaces of tibia and femur
