A Comparative Study to Evaluate the Efficacy of Janubasti with Erand Taila and Ksheerabala Taila in the Management of Janu Sandhigata Vata (Knee Osteoarthritis): A Single Blind Randomized Active Control Comparative Clinical Trial Protocol

Osteoarthritis is a chronic degenerative joint disease characterized by cartilage loss, osteophyte formation, subchondral sclerosis, and synovial changes, presenting with pain, stiffness, swelling, crepitus, and reduced mobility. In Ayurveda, it resembles Sandhivata, caused by Vata aggravation, Dhatu kshaya, ageing, and reduced Shleshaka Kapha, leading to pain, swelling, stiffness, and impaired function. Modern treatment is mainly symptomatic with limitations. Though Charaka Samhita describes Erand as Vatahara, evidence on Erand Taila Janubasti remains unavailable.
