It's been 5 weeks since left tkr and I've had it! I exercise twice a day, I ice twice a day, I have one of those little peddling bikes that you can sit on a chair and peddle and I do that for a 1/2 hour a day and still my knee is so stiff and tight. I'm beginning to wonder if I made the right decision to have this done. I am highly discouraged right now with all this, I expected more. I walk but as I walk I feel the knee tighten up even more. Has anyone one else experienced this? I'm beginning to think the worst and I don't want to give up. I promised myself I would fight through this, but I'm having second thoughts.
