P.T. is what makes or breaks a full recovery.
That’s what I would have thought. When my wife got her first TKR, she did a ton of P.T. and used a fancy machine that slowly flexed her knee for several hours a day. She recovered fine. When she got her second TKR, there was a communications and scheduling SNAFU. It was two weeks before she finally got to P.T. They did one session and sent her home with a few exercises to do on her own. Second recovery was better than the first. Go figure.
