Hello Doctor, I would be grateful if you could advise me on my condition. In 1993, while riding a two wheeler scooter, I met with an accident and got my right knee injured. In x-ray it was deteted to be torn ligament injury. The doctor attended to me did not advised for surgery at that time. Since then, I am unable to walk faster or run or play any out door game as while do ing so,my leg from knee is weak and it tilt/bend inside on its own due to ligament injury. Presently I am 50 years old. Can surgery cure this condition completely and I may be able to run and play games. Also tell me the cost of treatment in Delhi, India. Thanking you in anticipation.
