My dad is a month removed from knee replacement. He’s 62. Been limping around for years after a partial MCL tear and insufficient repair.
Already looks like he’s walking better than before. What i’m Saying is that the replacement may be a blessing in disguise.
Keep in mind that doctors’ first duty is to do no harm. “You can’t run” anymore is their advice to avoid harm. Take the PT seriously, and have her wear out that titanium knee. The surgical techniques and the hardware are only getting better.
