I tore my knee ligaments up about 30 years ago.
One doc told me I needed immediate surgery or I would have trouble walking for the rest of my life. He was quacking loudly as I left his office. Second opinion from a sports injury specialist said a pro ball player should get surgery, but in my case, with or without surgery as I got older the knee would give me grief.
I healed to the point that I could do what I wanted to do. Mtns, horses, hiking, dancing with the stars etc. But as I age I have had to drop some activies. No dancing With the stars or mtn climbing.
I can still move enough to chase " Yes Dear" but as age takes its toll I can't remember why.
It took about 4 mos before I could get very active.
Take it easy, and in my case the WCB doctor would have got a kick in the junk, except my knee was fubar.
