I came home about 8 hrs after my Rt TKA. I had my husband who knew what to expect from my PKA 5 yrs ago. And you are usually still under the effects of the block so pain isn’t bad on that first day. Just be prepared when the block wears off and have everything in place that you are going to need. Ice machine, pillows, somewhere to place your meds and water near you. I was nervous about coming home but with Covid, I really didn’t want to be at hospital any longer than I needed to be.
