I have Lupus and because of steroids the blood flow to my hips stop and they were crumbling, back in 2003. I was told I needed both replaced. That same day I saw on a news program where a Pittsburgh doc was doing minimal invasive hip surgery. I called my Lupus doc 's nurse and she found him. I had my R done Dec. 2003 and my left L 2004. Up out of bed same day with both. I went out to dinner with my walker the same day I got of the hospital that was 5 days after surgery. The doc said he could have done both the same day but, because of my Lupus he said he wanted me to have rest inbetween. I had two small incesions one in front and one in back.
