BoneSmart: Knee Replacement & Hip Replacement Community & Patient Resources. This website is great for anyone who either had or is thinking of having knee or hip replacement. I had both my knees done 9 weeks apart in 2008 at New England Baptist Hospital in Boston. No problems. Surgeon was/is one of the best in the country. When I moved to TV, he gave me recommendation for a surgeon here for follow-up. PM if you want the name. I have never used him but have attended one of his seminars at Waterfront Inn.
