What your PT showed you both is not elevating. It is a practice some people use for increasing extension. It's totally unnecessary at this early stage and should only be done for short periods later in your recovery. Keep on elevating as shown in this article - Elevation is the key to controlling pain and swelling - because you are aiming to decrease the swelling in your knee and leg. Get rid of some of that swelling and your knee will both bend and straighten more easily.I think my wife is a little upset that I'm not elevating the way the PT instructed. He said to just place a pillow under the ankle ( for extension). The PT measured my flex at 90, but didn't measure extension. I know you could stick a fist under my knee before surgery, so I know that needs a lot of work.
It sounds as if your knee was already bent before your surgery, so the muscles and tendons at the back of your knee will have shrunk a bit. It will take time, patience and gentle treatment to stretch those tissues again.
Don't let anyone hassle you about that or try to force your knee to straighten. You have plenty of time, because ROM, both flexion and extension, can continue to improve for a year or longer after a TKR. You don't have to meet any deadline.
One more thing: This is your knee and you are the only one who has the right to say what will happen to it. You are in charge of your recovery, not your surgeon, your PT therapist, or your wife.
