Someone commented on this blog that her mother was afraid to have a hip replacement because she has scoliosis. I made sure my surgeon knew in advance about the scoliosis and adjusted so I was a bit less unbalanced after than I was before. It had absolutely no effect on my recovery, however, or on the severity of the operation.
I'm now 3.5 years out and I don't even remember I have it most of the time. Of course I still keep in shape assiduously, which was the way I was before.
