Ya know that feeling you get in your knee(good or bad one...lol), where it's like your knee gets stuck and you have to move it to get it past that point, and it pops/cracks?  Today, I was getting dressed and didn't feel the pressure like when that would normally happen, but heard a pop, didn't hurt...but I've noticed since then, my walking has been easier, not feeling as tight in my knee.  Anyway, did anyone else have this, notice this after an ACL reconstruct?  I go back for a check up on Wed and will ask then, just thought I'd see here as well.
