Hello and thank you for your question,
There should not be a problem with you flying for an hour. You might need to get up several times and walk back and forth during that flight just to keep blood circulating but otherwise there is no contraindications for flying.
If you had plates put in during surgery, you might need a note from your surgeon so that if the security alarms go off, you can show the security your medical clearance.
I hope you find this information helpful. Please feel free to follow-up with any other questions you might have.
