Thanks so much to the KneeGuru and Heather for the advice! This board is a great place--it was so comforting to find out that somebody else had had this happen, too.
I went back in to see my surgeon yesterday. He said that I'm right in thinking that it is not infected (not hot, nor do I have a temp). He almost exactly echoed your words, Heather, and said that some people just heal slower and it is taking more time for this wound to knit back together--the problem is that it is exactly where my knee bends, so the incision pops back open.
I am now wearing a knee immobilizer, which keeps my whole leg totally straight. I think it will also serve to keep my whole body immobilized as walking with it has given me aches and pains in my back and everywhere else!! Also, continuing to take my antibiotics. He will re-check me on Monday.
I guess age does play a factor in this type of surgery. I had both knees operated on at 18, and then again at 32--all were lateral release and general clean-up of arthritic damage. The first set was easy--I was out dancing a week after surgery at 18. The second set of surgeries took longer to for the pain and swelling to reduce--I also had them about 5 weeks apart, which was stupid (I learned the meaning of "no leg to stand on"
during that rehab process! ).
Now, at 39, I can't even get the silly wound to close up!
Thanks again for your kind words and advice -- GREAT MESSAGE BOARD!!
