Paula, please try not to get discouraged, you are doing well and we all have ups and downs in this recovery, it's just that we don't like the downs. I'm upset that I seem to be making progress at a snails pace, but as you said a lot depends on how much your knee has been through already and you have had lots of surgeries previously. About the bruising you noticed, I've had what looks like bruising around the inscision until fairly recently. If we could see exactly what was done to our knees we'd probably marvel at natures ability to heal, and it would help us be patient.
I hope there are more good days in store for you.
Love, Tabby xxx
