Hi Charlie,
I am wondering what kind of weight bearing you mean? Full weight on the operated leg, or, lifting weight with the leg or upper body? Either way I think the advice to take it slow and be cautious is key. Regarding weight bearing on the operated leg, the only direction I received was to "play with it", which I did and I retreated anytime I felt any discomfort - by that I mean when I went from 2 crutches to one, as soon as it did not feel good I grabbed the 2nd crutch for the rest of the day; when I went from 1crutch to the cane, same thing, as soon as it became uncomfortable I went back to the crutch, etc. For weights on the legs, if that is what you mean, I think you should have the guidance of a physical therapist.
Good luck! And pleeeeaaaase, don't overdo it. (Are you getting tired of hearing that?)
