Evaluation of clinical symptoms and sonographic characteristics of femoral trochlear cartilage in primary knee osteoarthritis
Objective: This study was designed to evaluate the clinical symptoms and sonographic characteristics of femoral trochlear cartilage in patients with knee joint osteoarthritis (OA). Methods: This cross-sectional study was conducted on 94 patients with painful primary knee OA according to the American College of Rheumatology criteria with a visual analog scale pain score of 30 mm or more. Clinica...
متن کاملQuantification of bone marrow lesion volume and volume change using semi-automated segmentation: data from the osteoarthritis initiative
BACKGROUND To determine the validity of a semi-automated segmentation of bone marrow lesions (BMLs) in the knee. METHODS Construct validity of the semi-automated BML segmentation method was explored in two studies performed using sagittal intermediate weighted, turbo spine echo, fat-suppressed magnetic resonance imaging sequences obtained from the Osteoarthritis Initiative. The first study (n...
متن کاملQuantification of Knee Cartilage In Vivo In the MMT Model of Osteoarthritis in Rats Using MRI
Introduction Preclinical drug development in the area of osteoarthritis (OA) requires robust and reliable assessment of disease progression. The morphology of the articular cartilage is considered to be the primary marker of OA progression. However, the challenges of small animal in-vivo imaging and image analysis have limited the use of MRI in preclinical OA research. We present an approach fo...
متن کاملQuantitative Cartilage Imaging in Knee Osteoarthritis
Quantitative measures of cartilage morphology (i.e., thickness) represent potentially powerful surrogate endpoints in osteoarthritis (OA). These can be used to identify risk factors of structural disease progression and can facilitate the clinical efficacy testing of structure modifying drugs in OA. This paper focuses on quantitative imaging of articular cartilage morphology in the knee, and wi...
متن کاملKnee cartilage loss in symptomatic knee osteoarthritis over 4.5 years
The objective of this study was to describe the rate of change in knee cartilage volume over 4.5 years in subjects with symptomatic knee osteoarthritis (OA) and to determine factors associated with cartilage loss. One hundred and five subjects were eligible for this longitudinal study. Subjects' tibial cartilage volume was assessed by magnetic resonance imaging (MRI) at baseline, at 2 years and...
