Patient: I had a meniscus in my left knee repaired in Dec. 2014. My knee keeps swelling up and causing a lot of pain. Have been back to the surgeon several times and got a shot of cortisone on one occasion which helped briefly. It is getting to the point that it is getting hard to work or perform my daily routine. The doctor says that I have some arthritis, but not an excessive amount for 66 years old. So what should my next step be.
