Legg calve perthes now evovled to hip dysplasia and i now have pains when being too active. what to do? some say a ganz(pao) operation could be good?

Listen to hip doc: Lcp disease distorts the shape of the hip joint. A ganz osteotomy attempted to gain coverage over the deformed femoral hip that the acetabulum no longetr is able to provide. It can give relief from the joint pain and increase your function. There are over osteotomies i=of the pelvis as well. See a doc that specializes in hip problem with extensive experience and long term results.
