I tripped during a x-country race in 2008 and partially tear my left medial horn. I essentially had a piece of meniscus flapping in the breeze in my left knee. I was 48 at the time.
First doctor told me he couldn't fix it and that my running days were gone.
Second doctor told me he could perform surgery and reattach it but it may not heal correctly and I would still be in pain. There isn't a lot of blood flow in that area.
Third doctor was the orthopedic doctor for the NY Jets. (the advantages of living in the Tri-State area). He essentially told me to "man-up." He said that with the proper PT and sufficient amount to guts I should be able to go back to doing whatever I wanted, as longs as I didn't mind a little pain.
11 years later and here I am, still doing whatever I want, although there are nights when the only way I can go to sleep is with ALEVE. I don't go to PT any longer, but I still do the exercises on my own when I think about it. It isn't exactly brain surgery
Small price to pay.
