A bioengineered molecule designed to bind together key components found in the fluid that surrounds joint areas may improve lubrication and minimize friction. This could potentially slow the degeneration of cartilage tissue that occurs in knee osteoarthritis, according to a study conducted in rats and funded in part by the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases. The study was published in Nature Materials. The synovial fluid that bathes our joints is composed of several types of lubricants, including hyaluronic acid (HA) and lubricin. In healthy joints, this fluid ensures that tissues move together smoothly and without
Using magnetic resonance imaging (MRI), a team of scientists has detected structural changes in the knee joint that precede signs of osteoarthritis seen on X-rays. The study, which was supported in part by the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), calls into question the assumption that damage to cartilage is the primary underlying cause of osteoarthritis. The findings appeared in the journal Arthritis and Rheumatology.
Musculoskeletal conditions like spinal stenosis and anterior cruciate ligament (ACL) tears in the knee affect people of all ages and can be debilitating. Recently reported long-term data from two large-scale studies funded in part by the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases provide clinically valuable insights into the outcomes associated with treatments for these common, and sometimes costly, orthopaedic problems. Benefits of surgery for spinal stenosis diminish over time Data from the Spine Patient Outcomes Research Trial (SPORT) suggest that patients with severe low back pain caused by common spinal conditions who undergo surgery initially have
