Laser heat therapy could ease knee pain without smoke

This study tests whether adding a special laser treatment (CO2 infrared laser moxibustion) to standard exercise can reduce knee pain and improve movement in people with knee osteoarthritis. About 68 adults aged 55-65 with knee arthritis will receive either exercise alone or exercise plus the laser treatment over 8 weeks. Researchers will measure pain, knee motion, and cartilage changes at 3 and 6 months to see if the laser provides extra relief.
