Just wanted to offer my experience to anyone considering bi-lateral resurfacing in the future. I'm a 60 year old active femaile who had my resurfacing(s) done at UCSF with Dr. Tom Vail 6 weeks ago. By week 4 I was without any walking aids or pain meds and at week 6 I'm swimming , going to water aerobics 3 times a week, walking, doing yardwork and all my housecleaning and working full time. I have a little stiffness if I sit too long or work out too hard but otherwise I'm pretty much back to normal. The first couple weeks are very hard but preparation is everything. I planned this surgery for 6 months so I had plenty of time to research and implement my pre-surgery exersize routines and post surgery needs. If you are considering a bi-lateral, I have a wealth of info.
