OBJECTIVE: To investigate whether higher daily cumulative hip moment at baseline is associated with subsequent radiographic progression of hip osteoarthritis (OA) over 12 months. DESIGN: Fifty patients with secondary hip OA, excluding patients with end-stage hip OA, participated in this prospective cohort study. Joint space width (JSW) of the hip was measured at baseline and 12 months later. With radiographic progression of hip OA (>0.5 mm/year in JSW) as dependent variable (yes/no), univariable and multivariable logistic regression analyses were performed to assess the association between load-related parameters during gait (i...

The extracellular matrix (ECM) of articular cartilage is comprised of complex networks of proteins and glycoproteins, all of which are expressed by its resident cell, the chondrocyte. Cartilage is a unique tissue given its complexity and ability to resist repeated load and deformation. The mechanisms by which articular cartilage maintains its integrity throughout our lifetime is not fully understood, however there are numerous regulatory pathways known to govern ECM turnover in response to mechanical stimuli...

OBJECTIVE: Among high risk individuals, whether knee lesions in tissues involved in osteoarthritis can improve prediction of knee osteoarthritis is unclear. We hypothesized that models predicting 1) incident osteophytes and 2) incident osteophytes and joint space narrowing can be improved by including symptoms or function, and further improved by lesion status. DESIGN: In Osteoarthritis Initiative participants with normal knee x-rays, we assessed cartilage damage, bone marrow lesions (BMLs), and menisci...

OBJECTIVE: Whether meniscal extrusion and bone marrow lesions (BMLs) are independently associated with the risk of knee osteoarthritis (OA) is unknown. METHODS: Data was extracted from the Osteoarthritis Initiative (OAI) cohort. Participants were grouped according to the absence (Kellgren-Lawrence (KL) grade ≤ 1, n = 2120) or presence (KL ≥ 2, n = 2249) of ROA. Baseline meniscal extrusion and tibial BMLs were assessed. Tibial plateau cartilage volume was assessed at baseline and 72 months, while radiographic disease was assessed at baseline and 48 months...

INTRODUCTION: Matrix metalloproteinases and 'aggrecanase' ADAMTSs are well established to play key roles in osteoarthritis (OA) through degradation of extracellular matrix type II collagen and aggrecan, and are thus potential targets for development of OA therapies. OBJECTIVE: This paper aims to provide a comprehensive review of the expression and potential roles of other, lesser-known ADAMTSs and related adamalysins (or ADAMs) in cartilage, with a view to identifying potentially protective or homeostatic metalloproteinases in the joint and informing consequent selective inhibitor design...

OBJECTIVES: Studies show limited improvement in the frequency of engaging in life activities after joint replacement. However, there is a paucity of research that has examined factors, including other life events, which influence engagement following total hip replacement (THR). This research sought to identify factors associated with engaging in life activities following THR. METHODS: A prospective cohort study was conducted with 376 people who had a THR for osteoarthritis...

OBJECTIVE: Preclinical evidence suggests that increased cholesterol levels might be involved in the pathophysiology of osteoarthritis of the hand (HOA), but evidence from observational studies remains scarce. We aimed to analyse the association between hyperlipidaemia and incident HOA. DESIGN: We conducted a matched (1:1) case-control study using the UK-based Clinical Practice Research Datalink. Cases were patients aged 30 to 89 years with an incident diagnosis of HOA between 1995 and 2014...

OBJECTIVE: To investigate the presence of inflammation and resolution pathways in osteoarthritis (OA). DESIGN: Tissues were obtained from knee OA patients and control rheumatoid arthritis (RA) patients. Cells in synovial fluid (SF) were visualized by flow cytometry. Cytokines and chemokines were measured by multiplex assay. Lipid mediators (LMs) were determined by targeted lipidomics using liquid-chromatography mass spectrometry. RESULTS: SF of OA patients contained less cells, especially neutrophils, less cytokines and comparable levels of chemokines compared to RA controls...

OBJECTIVE: Lipocalin-2 (LCN2) is an adipokine that was first identified in neutrophil granules. In the last years it was recognized as a factor that could impair chondrocyte phenotype, cartilage homeostasis as well as growth plate development. Both pro-inflammatory cytokines and glucocorticoids (GCs) modulate LCN2 expression. Actually, GCs were found to be LCN2 inducers, suggesting that part of the negative actions exerted by these anti-inflammatory drugs at cartilage level could be mediated by this adipokine...

OBJECTIVE: To investigate the longitudinal association between endogenous sex hormones and knee OA structures and pain. METHOD: We examined 200 participants (mean age 63.0 ± 7.3 years) from a clinical trial of vitamin D supplement for symptomatic knee OA. Serum levels of estradiol, progesterone, testosterone and sex hormone binding globulin were analyzed at baseline and 24 months later. Magnetic resonance imaging scans of selected knee were obtained at both baseline and follow-up for the measurement of cartilage volume, cartilage defects, bone marrow lesions (BMLs) and effusion-synovitis volume...
