Experienced Arthritics Here?

I have had knee arthritis since age 52. Stopped running at 55. Have done a lot of research on this and talked to a lot of folks that have had the knee scopes. None were happy with them including my younger brother. Coincidentally I am waiting for his call to pick him up from the WPB VA hospital and drive him to a nursing home as I read this thread. He just had a total replacement of his right knee. He is 62 I am 66 now. I continue to take Glucosamine chondroitin and fish oil which has helped along with exercise and some bike riding to strengthen the muscles that support the knee.
