Swelling behind knee

Posted by rknee @rknee, Dec 20, 2020

My TKR was 3 months ago and the swelling behind my knee feels like a pocket of fluid. I think it’s the reason I can’t sit more than half an hour. My doctor just says “some people have that” or “give it time”. I have tried using the roller back and forth over it but it doesn’t seem to be reducing the swelling. Has anyone else experienced this and were you successful in reducing the pocket of fluid?

@rknee, you might find some helpful tips in this related discussion:

Swelling isn't uncommon, even 3 months after surgery. Are you still elevating your leg regularly? Do you know about doing foot pumps to keep the blood and lymph systems flowing?

Good afternoon @rknee. You are having some unwanted issues with your "new" knee I see. At three months post-surgery, I would hope for things to have settled down a bit but I know that knees are transplanted into unique different folks with different experiences. I notice that you have had only one knee replaced. What about the other knee? Does the non-surgical knee have the same "pocket of fluid"? Did the surgery knee have a "pocket of fluid" prior to the replacement?

The reason I am asking is that what you described sounds a bit like "Baker's Cyst". It is the way our bodies try to protect us. However, it can become a nuisance. My first effort was to go back to my orthopedic surgeon who did the appropriate imaging and have the fluid extracted prior to the surgery. He told me that the surgery would predominantly take care of it.

Now…that felt pretty "A-OK". Only one problem…..the pocket fills up again as long as there is something to disturb that area of the knee. He did not want me to constantly have to have the pocket drained and so recommended the replacement.

But guess what…..now the other knee, which has had no surgery has a "Baker's Cyst". We are using the MFR to keep it under control as I am not interested in having another knee replacement at this time. Here is the link to the Mayo Clinic discussion of Baker's Cyst.

I didn’t have the problem until after knee replacement and the non-surgical knee has no issues other than mild arthritis pain in the joint. I am not going to have surgery on that knee until I absolutely have to due to all the other problems I’m having after right knee replacement. I have stopped icing and elevating since my knee itself is better but sounds like it might help the back of the knee so I will start doing it again and see if it helps the Bakers Cyst go away. Thanks for the advice!
