Dear Kris,
Well I can absolutely see why you would feel the way you do about your knees. Let them not overwhelm you with insecurity or distorted body image. Why? Because however "we" see ourselves...to other people it is only half as bad! It effects us more because it is our own body. Last summer when my knees were like you described, LARGER THAN MY THIGHS, I thought people would gawk & stair...but I was surprised that they were more "concerned & interested" that FREAKED OUT! lol.
OK, I might not remember correctly...but what rheumatic disease do you suffer? Was it RA?
From what I understand, the soft tissue behind your knee is severely swollen? This would be behind the patella? (Just want to make sure I know what I'm looking at!)
If the soft tissue is involved only, this sounds like marked edema stemming from something.
In rheumatic diseases a knee would look like this from: bone overgrowth, collagen overgrowth, long term damage from RA/OA, an infection of some sort like osteomyletis, or as simple as an acute flare resulting in tremendous fluid accumulation.
When did this occur?
Can you describe the pain if any?
Also, take your temperature to see if you have a fever.
Imobilizing the knees by wrapping them, elevation, and some ice application can reduce some swelling.
If this is acute...the knees should return to normal appearance once the edema goes down.
If this is something that has been developing over time & is actual joint deformity, than an orthopeadic surgeon consult is needed along with a rheumatologist.
What is your history with all of this that is going on?
Take care & please write back soon. I would like to help you more...but I need a wee bit more information. Sincerely, Erin
