Yikes. Months? I've had two top surgeries. First one was Jan. 2009. The surgeon botched it, big time, so I needed another complete surgery this past Sept. (The first one was such a disaster that my revision qualified as medically necessary and was covered by insurance.)
But anyhow... after each surgery, my recovery was the same: I was back to running 3 1/2 weeks after surgery, and back to light weight-lifting (nothing above the shoulders) after 6 weeks. Returned to my full weight-lifting routine around 8 weeks after surgery.
No problems whatsoever. I might have good genes: My dad has had around 10 surgeries over the years, with very quick recovery times.
