I have been having problems with my knees for about 4 1/2 yrs, now. I started working on concrete floors and it all came about pretty quick. I got a pair of Z-coil shoes and they really help, but the situation is getting worse. We have no insurence and I have not even been to a specialist yet, only chiropractors and I finally said something to my M.D. I didn't want a trail with doctors if we could get insurance. So, they believe I have bone on bone. My mother just had both of her knees replaced last year, she is 80, I am only 54. Any suggestions? Anybody know of any programs that are out there to help the uninsured? Somebody suggested Cleveland Clinic, someone else thought Ohio State had a program?
