Each year on October 12 the world observes Arthritis Day to bring attention to the medication condition and ways to find out to prevent and to treat it as there is no cure. However, apart from the traditional treatments like medication, physical therapy, lifestyle changes, and surgery to manage symptoms, there have ben new treatments in the recent times too. Before jumping into what those treatments are, let us first understand what is arthritis?It is a medical term for joint pain, inflammation, and stiffness, with over 100 different types. It also includes osteoarthritis and rheumatoid arthritis. Osteoarthritis: It is a progressive, degenerative joint disease where the protective cartilage cushioning the ends of the bones breaks down. It then causes pain, stiffness, swelling and reduced mobility and affects the hands, knees, hips and spine. Rheumatoid Arthritis: It is a chronic autoimmune disease that causes pain, swelling, stiffness, and warmth in the joints and affects mostly small joints of hands and feet in a symmetrical pattern. It occurs when the immune system attacks the body's own tissue, particularly the lining of the joints and leads to inflammation or even damage to cartilage and bones.What Are The New Treatment On Arthritis?As per the multiple new studies present at the American Society of Radiation Oncology (ASTRO), 2025, researchers from Korea, the US, and Germany reported that mild doses of radiation can significantly reduce pain and also improve mobility in patients with osteoarthritis. Radiation Therapy For ArthritisIn South Korea, a randomized clinical trial was conducted with 114 volunteers, who had knee arthritis, and were treated with 3 Gy of radiation, which had spread over six sessions. Researchers also noticed that 70% of participants experienced meaningful improvement in pain, function and overall functioning. This was way higher than the 42% improvement seen in the placebo group. Low-dose radiation is already common in the Europe. However, strong randomized data was limited till now. Dr Byong Hyuck Kim of the Seoul National University, who led the study also emphasized that here, the radiation doses are 10 to 20 times lower than cancer therapy levels and targets only the joints far from the vital organs. Artificial Cartilage Helps ArthritisResearchers from the University of Cambridge designed an artificial cartilage that could help with arthritis treatment. This 'cartilage' can sense tiny changes in the body, including arthritis flare-up and release drugs exactly when and where they are needed. The 'cartilage' is squishy in nature and can be loaded with anti-inflammatory drugs that are released in response to small changes in pH in the body. During arthritis flare-up, joint becomes inflamed and more acidic. The 'cartilage' becomes softer as the change in pH is noticed, especially when the acidity increases and it triggers the release of drug molecules that can be encapsulated within its structure. The entire study is published in the Journal of American Chemical Society.
