osteoarthritis
"Synvisc gave me significant, almost immediate relief from the bone-on-bone pain in my knees. Since then, as I continue to learn about my knee problems, I now understand that some of the pain is in the tendons around my knees, which are inflamed due to severe bow-legs. Still don't understand why the bowing is increasing with my age, but this forces my tendons to stretch in an incorrect manner, more on the inside of each leg than on the outside.  Unfortunately Synvisc cannot address this problem, although it does provide a nice separation between the joint surfaces which also suffer from excess pressure on the inside portion of each knee. I am currently looking into shoe wedges to improve leg straightness by preventing excess supination."
