I was just curious if those of you with one new knee replacement notice a big difference in size with your other knee. I had a RTKR in January and it is feeling strong but it is hard to bend much beyond 90 degrees. My PT could push it to 105 with much pain but it always felt like knee was going to pop out of skin. It is much larger in size than my left knee which doesn't need to be replaced (hopefully never!) and I am wondering if this is normal? Could the size of it be prohibiting the bending??
