Since knee surgery my standing balance is worse. I have repeatedly stumbled backwards because I cannot feel when I am leaning too far behind vertical. Losing my balance was the first symptom of my two brainstem strokes.
My strokes were caused by narrowing of the vertebral artery that supplies blood to the pons. The pons in the brainstem is the bridge to the cerebellum which controls balance.
There is a chance that bending my neck back to put a breathing tube down my throat during surgery put a kink in the vertebral artery in my neck. If a 15 minute meniscal repair surgery impaired my balance, I do not want to see what happens after a longer knee replacement surgery.
Bottom-Line: I am serious about the exercises I got from my latest PT.
