From bilateral torn meniscus to TKR and still swelling and in pain

About five years ago I was told I had Degenerative Joint Disease and that I had torn the meniscus in both knees. Arthroscopic surgery was done and it was downhill from there!! Pain worsened as did the swelling. Finally in 2002 I could not go on and this time I was told that both knees needed TKR due to Osteoarthritis. My knees were rubbing bone on bone. In October, 2002 I had the left TKR, In November, 2002 I had the knee surgically manipulated because I could not bend it beyond 45 degrees. The pain and swelling from day one never ceased. I continued to complain about pain in a particular area on the inner aspect of the knee and well as the regular pain. Generally, when I get up in the morning the knee is less swollen but as the day progresses, particularly if I run errands and or cook, etc. any activity that requires me to be on my feet, the knee swells and of course with the swelling comes more pain. I am now being told that I may have to have another surgical procedure to correct the kneecap which is rubbing as I use the leg and this rubbing is causing inflamation and in turn the pain and swelling. Originally, both TKRs were to have been completed by April, 2003 and I would be back at work. Now it would appear I may never get back to work. I haven't even mentioned the depression or the financial implications!!! I am a 57 year old single female with a mortgage and not much else unless you count pain and swelling.
