I wish you the best possible recovery.
FWIW my younger brother, HS wrestler, college football, had a kneecap removed years ago from an auto accident. It was called his bad leg.
A few years ago, while riding 4 wheel ATV, he ran over his good leg, snapping tibia and fibula. He had surgery with rods.
Doctors told him that he would likely wind up with a limp. He went through painful physical therapy, and walks without a limp.
His advice to me when I later had a very serious shoulder fracture: Do the therapy, no matter how painful.
Again wishing you the best possible recovery.
I seem to thrive when facing adversity. I lean into it and push hard, like we do.
