Adult human joint cartilage lesions do not spontaneously heal. Patients with isolated articular cartilage lesions make up perhaps some 1% of the total number of patients examined by arthroscopy. Symptoms such pain and locking, and the suggestion that the untreated lesions may progress to osteoarthritis form the basis for current attempts to repair articular cartilage by cell transplantation and ot

Objective: To further our understanding of the pathogenesis of chondromalacia of the patella (CM), we have studied the release into knee joint fluid and serum, obtained from patients with CM, of molecules associated with the metabolism of joint cartilage matrix and synovium. Methods: Interleukin-1 α (IL-1α), interleukin-1 β (IL-1β), interleukin-6 (IL-6), stromelysin-1 (MMP-3), interstitial collage

Objective. To study the long-term outcome of surgical removal of a meniscus in the knee with regard to radiographic signs of osteoarthritis (OA). Methods. Of the 123 patients who underwent an open meniscectomy due to an isolated meniscus tear in 1973 at Lund University Hospital, 107 were followed up 21 years later by clinical examination and by review of knee radiographs obtained with weight beari

We report the incidence of total hip replacements performed in Iceland between 1982 and 1996. During this period, 3403 hip arthroplasties were done. The annual number of procedures increased from 94 hips in 1982 to 323 hips in 1996. Annual rates of total hip replacements due to primary osteoarthrosis per 105 inhabitants were 68 in 1982-1986, 90 in 1987-1991, and 114 in 1992-1996. In the years 1992

Objective: To compare the sensitivity of WOMAC and the two added dimensions Sport and Recreation Function and Knee Related Quality of Life in subjects with radiographic knee OA to that in controls. To study the influence of age on the reported outcomes. Design: Outcomes were compared between subjects having had meniscectomy 21 years ago and which at time of follow-up had definite radiographic OA (

Objective. To investigate the in vitro effects of 6,7-dihydroxycoumarin (esculetin) on the production of matrix metalloproteinases (MMP) in rabbit articular cartilage, and the in vivo effects of orally administered CPA-926, a prodrug of esculetin, on cartilage destruction in rabbit experimental osteoarthritis (OA). Methods. In vitro studies were performed using rabbit articular cartilage explants.

In China, the strategic use of personal relationships is pervasive in transactions with government authorities as well as in inter-firm relations. Explanations as to when and why firms rely on guanxi emphasize a close link between organizational resources, environment and corporate strategic choices. Our study shifts attention to the importance of CEO preferences, specifically risk aversion, and s

Based on small to moderate effect sizes for the wide range of symptomatic treatments in osteoarthritis (OA), and on the heterogeneity of OA patients, treatment guidelines for OA have stressed the need for research on clinical predictors of response to different treatments. A meta-analysis to quantify the effect modified by the predictors using individual patient data (IPD) is suggested. The initia

Objective: To update evidence for available therapies in the treatment of hip and knee osteoarthritis (OA) and to examine whether research evidence has changed from 31 January 2006 to 31 January 2009. Methods: A systematic literature search was undertaken using MEDLINE, EMBASE, CINAHL, AMED, Science Citation Index and the Cochrane Library. The quality of studies was assessed. Effect sizes (ESs) an
