I was skiing when I tore my acl. I asked my OS what it meant and he said I should see my regular md and that it was probably due to age. I am 52. He said he wants to slow down my rehab. I'm just not sure exactly what that means . Should I be walking and how much? The past two weeks have been spent mostly in bed with my leg elevated amd iced. So much so that my back and neck are beginning to hurt worse than my knee and I simple walk down the hall is exhausting. The therapists say this is ok, to take it slow. I guess I just want something more concrete. I have wonderful guidelines for the exercises. It would be nice if it included something like get up and walk once every hour.
