If it's an option Lynn, check out Dr. Dearborn here in Cali.
http://www.dearbornsah.com/ He's one the best Orthopedic Surgeon's out there. At age 70, my Mother had both of her knees replaced by him...at the same time! It's been several years now and she still doesn't have a problem with her knees. He now has his own floor at the hospital staffed with his own people to help you with your recovery.
They also do hips there...
I have a torn meniscus in my right knee and I'm avoiding arthroscopic knee surgery for as long as I can.
