Suncag,
Been there, done that. I had my right hip resurfaced in 2006 by Dr. Pritchett. It was a wonderful procedure and I was completely happy. Last spring, an MRI showed that I had some fluid build up around the joint. Dr. Pritchett recommended a revision. I consulted with several surgeons and most of them agreed. One would have replaced the entire joint with a THR; two others would have replaced the femoral component with a device that looked like a THR piece. After significant consultation, I went back to Dr. Pritchett. He replaced the acetabulum cup and left the femoral component alone. That was on Sept 18, 2018. Recovery has been very smooth.
Because I have osteopenia, Dr. P recommended a 4 month course of Tymlos, which is a bone building drug normally prescribed to patients with severe osteoporosis. Since bone health is key in the longevity of any prosthesis, i decided to do that. Will see if it makes a difference. Am hoping to have my HR (and THR in other hip) for a long time. Am an active 67 year old female.
