BACKGROUND The purposes of the study were to determine the relevance and validity of in vivo non-invasive radiographic assessment of the CCLT (Cranial Cruciate Ligament Transection) rabbit model of osteoarthritis (OA) and to estimate the pertinence, reliability and reproducibility of a radiographic OA (ROA) grading scale and associated radiographic atlas.(More)
Clinical practice guidelines have been elaborated to summarize evidence related to the management of knee osteoarthritis and to facilitate uptake of evidence-based knowledge by clinicians. The objectives of the present review were summarizing the recommendations of existing guidelines on knee osteoarthritis, and assessing the quality of the guidelines using(More)
OBJECTIVE To compare type II collagen degradation using a new urinary specific marker in patients with rapidly destructive and those with slowly progressive hip OA. METHODS Twelve patients with rapidly destructive and 28 patients with slowly progressive hip OA were included in a prospective, cross sectional case-control study. Urinary levels of C-terminal(More)
OBJECTIVES To evaluate the rate of progression of radiological joint space narrowing (JSN) in patients operated on for hip osteoarthritis (OA) and to determine its predictive factors. METHODS STUDY DESIGN retrospective longitudinal trial of 61 patients who underwent total hip arthroplasty (THA) for hip OA (69 operated hips). Mean follow-up 81.2 +/- 9.9(More)
Joint space width (JSW) and narrowing (JSN) measurements on radiographs are currently the best way to assess disease severity or progression in hip osteoarthritis, yet we lack data regarding the most accurate and sensitive measurement technique. This study was conducted to determine the optimal radiograph and number of readers for measuring JSW and JSN.(More)
Using radioligand binding assays, histaminergic H1, serotoninergic, dopaminergic and Beta adrenergic receptors were studied in human normal and osteoarthritic cartilage. The four studied receptors were present in normal cartilage; serotoninergic, dopaminergic and Beta adrenergic receptors were significantly increased in osteoarthritic cartilage while(More)
The aim of the session was to discuss the current definitions of and criteria for hand osteoarthritis (OA) and to review the tools proposed for the clinical assessment of hand OA in research and trials. The American College of Rheumatology criteria for the classification and reporting of hand OA were discussed and their limitations noted; specifically, they(More)
Joint surface area (JSA) and mean joint space width (MJSW) at the hip were measured using a ICMS-Techline computer program to analyze digitalised frontal weight-bearing roentgenograms of the pelvis. With this technique, the portion of joint space studied is always the same in a given patient and is enclosed within an acute ECS angle whose apex C is the(More)
BACKGROUND Measurement of radiographic joint space width (JSW) and of joint space narrowing (JSN) is the currently recommended method for assessment of anatomical severity and structural progression of osteoarthritis (OA), respectively. A standard radiographic view of the pelvis is commonly used for measurement of hip OA but other views are available. (More)
