I had a TKR last july and I am now 11 weeks pregnant. I have noticed that during sleep at night i am tossing and turning alot. When i turn in the bed I notice that the joint feels a little looser and pops and catches where it has not before. It sometimes hurts when it does this. It is just not the same and feels a little loose. Yesterday it swelled for no reason and when I walked down the stairs i had a bad pain right over my knee cap. Still this morning it is the same. I know they say your joints loosen when you are pregnant but what happens to a knee replacement.
These symptoms are quite common during pregnancy don't worry about them use simple analgesics like paracetamol
