Basti chikitsa which is being called Ardha Chikitsa is considered as the best treatment for Vata Vyadhi. Anuvasana basti is a type of Snehabasti which is indicated in Vata vikaras. Janusandhigata vata is one among the vata vyadhi characterized by sandishula, shotha, vedana during prasarana and akunchana of sandhi, vatapurna druthi sparsha and occurs mostly in old age due to Dhatukshaya which limits a person’s routine activities. Acharya Charaka has mentioned the use of Snehana, Swedana, Basti and Mruduvirechana as the treatment of Vatavyadhi. Janusandhigata vata can be correlated to Osteoarthritis of Knee Joint. Osteoarthritis of Knee Joint is characterized by focal loss of Articular Cartilage, Subcondral osteosclerosis, osteophyte formation at the joint margin and remodelling of joint contour with enlargement. Principally targets the patella-femoral and medial tibio-femoral compartments but eventually spreads to affect the whole of the joint. 

       The prevalence of osteoarthritis of Knee Joint rises progressively with age and it has been estimated that 45% of all people develop knee osteoarthritis at some point during life. Management includes Analgesics/topical NSAID, Oral NSAID, Joint replacement surgery, Strengthening exercises, etc. Now a days because of multiple influencing factors and bala of the patient, 1152ml/Dwadasha prasrutika niruha quantity is rarely practiced.
