[|Human|] Hi, I am interested in taking nonviscous hyaluronic acid treatments for knee pain. I am 69 years old and the doctor said the xray showed that the cartilage is almost gone. Is this a safe option for me ? I am trying to avoid knee replacement. Also, which is the best type for my treatment, and are nurse practitioners authorized to administer the injections?
[|AI|]  Dear patient injection of hyaluronic acid into the knee joint is helpful in early stages of osteoarthritis like stage 1 and 2. You said all the cartilage has gone means grade 4 osteoarthritis. In that case injection will not help. Better option is to go for total keep joint replacement. Hyaluronic acid injection should be given by authorized orthopedic practitioner expert in intra-articular injections. If you are not willing for surgery physiotherapy will be Better.
