Fracture complication with the plate

Back in Nov 2017, I fractured the right femur above and right next to a prosthetic knee implanted in 2006 which showed no wear as of last summer. It was a spiral fracture. I never had any pain in that knee after the implant of the replacement.....until now. When I mentioned it to the repairing surgeon, he said if it still bothers me after a year, he will remove the plate. I have an appt with the surgeon who did the implant of the prothesis. Has anyone ever had a supporting plate removed from the location of fracture? When I mentioned it to my physical therapist he said by then the plate has "grown" into the bone itself. That sounds like a complicated surgery and might have several possible complications which might make that "repair" not worthy of consideration.
Would appreciate any thoughts in this regard. @gailfaith .
