Gallic Acid and Stretching Decrease Osteoarthritis Markers in Cartilage Cells

A healthy diet and a little exercise appear to be good for arthritis, even on the cellular level. A team led by Washington State University researchers used gallic acid, an antioxidant found in gallnuts, green tea and other plants, and applied a stretching mechanism to human cartilage cells taken from arthritic knees that mimics the stretching that occurs when walking. The combination not only decreased arthritis inflammation markers in the cells but improved the production of desired proteins normally found in healthy cartilage.

While still at an early stage, the findings suggest a new procedure could be developed to treat cartilage cells extracted from a patient to grow a supply of cells or a tissue to be re-implanted.

“We found the com...

Novel assessment of Platelet-Rich Plasma Treatment shows Efficacy in Patients with Osteoarthritis

Knee joint pain

A pilot study conducted by researchers at Baylor College of Medicine combined wearable technology and patient-reported outcomes to assess the efficacy of platelet-rich plasma (PRP) treatment in osteoarthritis (OA).

The results, published in the journal Regenerative Medicine, showed that a single injection of leukocyte-rich/PRP in the knee joint significantly improved functional mobility, pain and quality of life after six weeks. The study supports using this combined approach to further evaluate this and other emerging biological therapies for musculoskeletal disorders in larger clinical trials.

“OA is a leading cause of disabilities, affecting nearly 52 million Americans,” said first and corresponding author Dr...

With Gene Therapy, scientists develop Opioid-Free solution for Chronic Pain

A gene therapy for chronic pain could offer a safer, non-addictive alternative to opioids. Researchers at the University of California San Diego developed the new therapy, which works by temporarily repressing a gene involved in sensing pain. It increased pain tolerance in mice, lowered their sensitivity to pain and provided months of pain relief without causing numbness.

The researchers report their findings in a paper published Mar. 10 in Science Translational Medicine.

The gene therapy could be used to treat a broad range of chronic pain conditions, from lower back pain to rare neuropathic pain disorders — co...

Novel technique ‘Stuns’ Arthritis Pain in Shoulder and Hip

A novel outpatient procedure offers lasting pain relief for patients suffering from moderate to severe arthritis in their hip and shoulder joints, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA). Researchers said the procedure could help reduce reliance on addictive opiates.

People with moderate to severe pain related to osteoarthritis face limited treatment options. Common approaches like injections of anesthetic and corticosteroids into the affected joints grow less effective as the arthritis progresses and worsens.

“Usually, over time patients become less responsive to these injections,” said Felix M. Gonzalez, M.D., from the Radiology Department at Emory University School of Medicine in Atlanta, Georgia...
