I was diagnosed with arthritis in my knees at age 52. I used to have to sleep with a pillow in between my knees to ease the pain. When I bought the MH at age 58 I could not drive more than 30 mins without getting that throbbing pain in my right knee and would have to extend my leg up on the dog house. That is when my wife learned to drive it. I later built a riser under the seat post that allowed me to extend my leg a little further. The seat could not go back anymore because it hit the slide. The raised seat helped a lot. I always drive in shorts and have various arthritis rubs next to me. In addition some trainers at the various gyms I went to over the years gave me some exercises to do to strengthen the muscles around my knees which helped even more. I have been taking Glucosamine chondroitin since 1998 and started taking fish oil in 2006. In taking the fish oil there was a noticeable difference. Now at age 69 I no longer sleep with a pillow between my knees and can usually drive several hrs before the pain sets in. So either I have convinced myself my knees are better or I just have learned to live with the pain better.
