Hi James,
My prayers for your rapid and complete recovery. I know about knee surgery, having had it back in the Dark Ages before there was arthoscopic stuff, etc.. Dr. said "Don't limp and you don't need crutches or a brace". Played 10 days later between draining sessions. Now I need a new one, too! Just listen to the Doc, do what you are supposed to do and don't feel like you have to be 100% in two days..
Looks like we will flip a coin as to whether I get shoulder, neck or knee surgery first! HAHAHA
Best Wishes!
Bill
