Hi,
I found that old habits die hard. Because of limping for so long, standing with my right leg slightly bent and all weight on my left leg, I found that I was still walking that way after surgery and standing that way too. It was drilled into me by my PT that be sure to heel toe walk and right now you really have to be very conscious of doing that. Use a regular stride and deliberately use the heel... roll to the toe. Also, did you have a pain pump used for your incision. If you did, that may be why you are still feeling numbness. I would have numbness off and on on the inside of my thigh, but not on the outside. But, like Pat said, all people are different.
When walking with your cane, be sure to be holding it on the opposite side of the operated leg and try to use the heel/toe walking. Remember.... you can walk normal now -- you don't have to limp because of the pain... that's what I found out anyway. I was off the cane at 3 weeks postop around the house and just used it while out. Completely off the cane at 5 weeks postop.
Good luck and keep us posted...
