Imaging Biomarkers of Knee Osteoarthritis

Not Applicable

Completed

• Conditions: Osteoarthritis
• Interventions: Device: PRISMA 3T MRI scanner (Siemens Medical Solutions)

• Registration Number: NCT02888119
• Lead Sponsor: NYU Langone Health

Brief Summary

This study aims to develop, evaluate and translate highly accelerated imaging sequences (each protocol under 5 minutes) for in-vivo knee Osteoarthritis applications on a standard clinical 3T scanner using novel compression sensing and parallel imaging strategies.The overarching objective of the study is to establish a non-invasive imaging biomarker based on the development of rapid relaxation mapping with compressed sensing (CS) that will be clinically useful for assessment of early Osteoarthritis. A total of 90 subjects including 30 patients with high risk of developing knee osteoarthritis (OA), 30 patients with mild OA and 30 healthy controls will be accrued.

Detailed Description

Current noninvasive imaging methods to evaluate knee joints include plain radiographs, computed tomography (CT), and clinical morphological magnetic resonance imaging (MRI) of joint structures. These techniques can only detect later-stage, macroscopic joint structural abnormalities that are irreversible and not amenable to early therapy. This study aims to develop highly accelerated imaging sequences for ex-vivo knee OA applications on a standard clinical 3T scanner using novel CS and parallel imaging (PI) strategies.

Arm && Interventions

Group	Intervention	Description
High Risk for Osteoarthritis	PRISMA 3T MRI scanner (Siemens Medical Solutions)	"High risk of developing knee OA" has been defined by having knee pain but normal radiographs (Kellgren-Lawrence score 0 i.e. KL0) on both knees but at least one abnormal finding on clinical MR protocol such as overweight, prior knee injury (ligaments or menisci) or traumatic bone marrow edema lesions.
Mild Osteoarthritis	PRISMA 3T MRI scanner (Siemens Medical Solutions)	-
Healthy Controls	PRISMA 3T MRI scanner (Siemens Medical Solutions)	Controls will be age/gender matched to patients within 2 years of age.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in T1ρ Relaxation Time	Baseline, Month 24	MRI exam of accelerated 3D-T1p conducted on whole knee joint specimens to determine cartilage composition, measured as T1ρ relaxation time. T1ρ MRI relaxation times refer to the proteoglycan density within cartilage.; Images taken at baseline and at Month 24.
Change From Baseline in T2 Relaxation Time	Baseline, Month 24	MRI exam of accelerated T2 conducted on whole knee joint specimens to determine cartilage composition, measured as T2 relaxation time. T2 relaxation represents the time constant of the molecular motion of water in cartilage, which is influenced by the composition of collagen and specifically reflects changes to the extracellular matrix. Images taken at baseline and at Month 24.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Western Ontario and McMaster University OA Index (WOMAC) Score	Baseline, Month 24	The WOMAC is a 33-item self assessment of how participants feel about their knee and how well they can perform usual activities. The questionnaire contains 4 separately scored subscales - Symptoms; Stiffness; Pain and Function; and Daily Living. The total score is a percentage score from 0 to 100; lower scores represent less pain, less stiffness, and better physical function; higher scores indicate greater pain, greater stiffness, and worse physical function. A decrease in scores indicates participants' health improved during the observational period.
Change From Baseline in Knee Injury and OA Outcomes Score (KOOS)	Baseline, Month 24	Knee-specific instrument, developed to assess patients' opinion about their knee and associated problems. The KOOS evaluates both short-term and long-term consequences of knee injury. It holds 42 items in 5 separately scored subscales - Pain; Other Symptoms; Function in daily living (ADL); Function in Sport and Recreation (Sport/Rec); and knee-related Quality of Life (QOL). The total score is a percentage score from 0 to 100; 0 represents extreme problems and 100 represents no problems. An increase in scores indicates participants' health improved during the observational period.
Change From Baseline in Physical Activity Scale for the Elderly (PASE) Scores	Baseline, 24 Months	Self-assessment of multiple domains of activity in older adults. Questions evaluate both occupational and non-occupational knee bending, squatting and stair climbing. Total scores range from 0 to 400 or above and are quantified based on frequency values and weights for these activities. Higher scores indicate higher levels of physical activity. An increase in scores indicates physical activity increased during the observational period.
