Here I am about a year after at least doubling the number of bone segments that comprise my patella. The funny thing is that although I had very little pain with my telemark fun last winter; I have chronic pain following two or more waterski sets. It is interesting in that the pain seems to lag the activity by two to four hours. Inflammation where the bone is damaged? Maybe, but I'm no doctor. "Everything in Moderation", is my plan - and so only one set for me at times. Still having a blast and skiing well.
