If you you can get on and off your Expedition now you'll have no problem once you have progressed far enough in your recovery.

My wife had a TKR a couple of years ago and had no problem riding her Catrike Trail. The key for her was excellent physical therapy and faithfully doing her exercise routine at home. And, in addition to her home exercises I set up an EZ-1 recumbent on a trainer. It took her a little over a week to make a full pedal revolution but after that she progressed rapidly.
