To Anyone. I had hip replacement surgery twice in the past year. The first was a standard titanium joint, which began dislocating after two months due to dyskensias. The second was a captured cup type, which has held now for three months, and feels more stable. I am 52 years old, and have had a slowly progressive case of PD since age 35 . I have been in good health, and able to lead my normal life pretty much. In the last year I developed some kind of acute inflamatory condition in the joint ending in aceptic necrosis of the femoral head. I have searched for YPD's who have had hip replacements with no luck. I'd really like to hear from anyone who knows about this, and has experience with the rehabilitation process. My muscles are quite atrophied after four months in a huge brace. My strength is slowly coming back--but very slowly, and I'm always afraid it will start to dislocate again, despite the captured cup. These weakened muscles overreact to the PD meds. and I have trouble with dyskenesia and dystonia in the hip when the rest of my body is fine. Thanks for any info. you might have. Claudia
