Increased risk of osteoarthritis in patients with atopic disease 

Objectives To determine the incidence of osteoarthrits (OA) in patients with atopic disease compared with matched non-exposed patients.Methods We conducted a retrospective cohort study with propensity score matching using claims data from Optum’s de-identified Clinformatics Data Mart (CDM) (January 2003 to June 2019) and electronic health record data from the Stanford Research Repository (STARR) (January 2010 to …

Insight into the assembly of lipid-hyaluronan complexes in osteoarthritic conditions

Interactions between molecules in the synovial fluid and the cartilage surface may play a vital role in the formation of adsorbed films that contribute to the low friction of cartilage boundary lubrication. Osteoarthritis (OA) is the most common degenerative joint disease. Previous studies have shown that in OA-diseased joints, hyaluronan (HA) not only breaks down …

Development of Osteoarthritis in Adults With Type 2 Diabetes Treated With Metformin vs a Sulfonylurea

Metformin may have a protective association against developing osteoarthritis (OA), but robust epidemiological data are lacking.Objective To determine the risk of OA and joint replacement in individuals with type 2 diabetes treated with metformin compared with a sulfonylurea.Design, Setting, and Participants This retrospective cohort study used claims data from the Optum deidentified Clinformatics Data Mart …

RORβ modulates a gene program that is protective against articular cartilage damage

Osteoarthritis (OA) is the most prevalent chronic joint disease which increases in frequency with age eventually impacting most people over the age of 65. OA is the leading cause of disability and impaired mobility, yet the pathogenesis of OA remains unclear. Treatments have focused mainly on pain relief and reducing joint swelling. Currently there are …

Exercise-induced piezoelectric stimulation for cartilage regeneration in rabbits

Osteoarthritis is a common condition, but curative therapies are limited. Here, Liu and colleagues developed a biodegradable scaffold using PLLA [poly(L-lactic acid)] nanofibers that when placed under applied force generated a piezoelectric charge, leading to improved chondrogenesis in vitro. Rabbits with osteochondral defects in the medial femoral condyle that were treated with the PLLA scaffold …
