I am 70 years aged male ailing from chronic Osteo arthritis left knee. So far have avoided replacement surgery and depended on periodic 3-4 years interval injections that helped me retain my mobility of free movement to my satisfaction. I shall now like to try out the cold laser therapy treatment. I need to know its curing ability by regenerating inoperative cells of cartilage and also the Hospital preferably located in NCR/Delhi area where you recommend me to undertake this treatment.
