Thanks. I'm a 4.0, could probably be a 4.5 if my body cooperated, but oh well.
ab70 - not really sure. It's definitely muscular, the mumford was just to give more clearance I think. They found little or no tearing at the time, and I rehabbed pretty quickly.
The knee is giving me the most concern at the moment. ACI is described as a pretty painful procedure with a 6-8 week non-weight-bearing period plus 3-8 months recovery time. And with a sub 50% success rate?
