By Erin Allen Left foot. Right foot. Don't limp. Repeat. That's been the droning cadence in my head for the last couple of weeks, as I've taken my first steps since ACL surgery on Feb. 26. I had six weeks of non-weight bearing, and I'm finally walking again. The sensation is strange. I feel this pressure in my knee, as if I can sense my joints squash against each other. I proceed at a pretty slow pace, because I'm having to consciously think about the movement I'm making. Hee
