Standing Computed Tomography (SCT) Imaging of the Knee Joint

May 21, 2021 updated by: Neil A Segal

Standing Computerized Tomography (SCT) Imaging of the Knee Joint in People With or at Risk for Knee Osteoarthritis (KOA)

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

45 years to 92 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

The existing 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 MOST 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 KL grade 4 (bone on bone). The new 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 KL grades of radiographic OA of 0, 1, or 2 in the tibiofemoral (TF) and patellofemoral (PF) compartments.

Description

Inclusion Criteria:

Only participants in the Multicenter Osteoarthritis Study (MOST) who attend a 0/144-month visit at the Iowa site are eligible for inclusion.

Additional Inclusion Criteria Include:

  • Completed knee radiograph (posteroanterior view) at 0/144-month visit of primary MOST-second renewal study at the Iowa Site

Exclusion Criteria:

  • Bilateral Total Knee Arthroplasty

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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.
