Well, there is a new drug, a synthetic compound similar to the fluid in normal knees. I'd contact my orthopedic specialist and inquire about this option, fairly new. Yes, this is a synthetic molecule similar to the fluid of a normal joint. It is injected into the joint usually about once a month for 3-4 times to see if it will relieve the pain of osteoarthritis. The early studies have demonstrated that it helps for about 2-3 years to delay joint replacement.
Risks center around infections at the injection site.
I have been experiencing swelling in the left foot and knee. I am also taking cardizem, lanoxin, and zocor for high blood pressure and cholesterol. No, asymmetrical swelling usually indicates a problem with the venous return from that leg. I have had two surgeries on my left knee. I continue, however, to have a lot of cartilage and fluid problems in my left knee.
