Hi Weezl, Are you more worried about the appearance of the knee, sizewise, or the way the knee is operating? I think it's two different things...... I'm 6 1/2 months post op and my new knee "appears" larger then my god given knee. I measured and the joint is one inch larger around. I do not think I am swollen. I think the dynamics of the knee is just different then my natural one. I really don't care as long as it works and the new knee seems to be working fine. Yes, I have a man knee also but I guess that's okay as long as they don't shoot me with testosterone!
If you have decent flex, movement and a limited amount of pain for this point in the recovery, personally, I wouldn't worry about a knee size difference. I'm happy to be rid of that horrible pain and have a knee that works. Of course, it's a whole different story if you feel excess pain or movement in the joint. I'm afraid I couldn't tell you much about that or even the symptoms.
Soon, I'll have my second tkr. Since I've had a scar that looked like a tkr scar on the 6 1/2 month old knee for 20 years, I'm going to tell the surgeon pre-op to make sure the scars match!!!! If I'm going to have another scar in my collection then I want them to match and be symetrical for once!
Good luck! Karen
