Randy, Perhaps you might have some adhesions around your knee cap? I also really pushed more with my first tka than my second. I recently had to have surgery to remove the scar tissue which has trapped my knee cap. After the surgery, I had a really slow recovery. My pt cautioned me that scar tissue or adhesions form when an inflamed knee is exercised.
So, it was slow, slow slow for me--three weeks of no pt, just sitting on the couch with ice. I still cannot believe how long it tooK. I am at 12 weeks now and just beginning to start really working out. I am sorry to hear of your knee and hope it gets resolved soon. It sounds like you have a great pt team. Kelly
