Red light therapy is a non-invasive treatment that uses low-wavelength red and near-infrared light to penetrate the skin and underlying tissues around the knee. It is believed to support cellular energy production, improve circulation, and help reduce inflammation, which may contribute to decreased pain and stiffness. Some studies suggest that red light therapy can provide modest relief for people with knee conditions such as osteoarthritis, although results vary and it is generally considered a complementary treatment rather than a cure. Regular sessions may be needed to achieve and maintain benefits, and it should be used alongside appropriate medical care and exercise when recommended by a healthcare professional
