Neurosurgeon Triathletes

By /


I‘ve only met one neurosurgeon triathlete, but my guess is that there are more.  We treated then 67 year old Joe Maroon, M.D.’s knee with his own stem cells about a year and a half ago.  He hadn’t run in a triathlon in 5 years and then after treatment went on to complete the Hawaii Ironman. I recieved this e-mail from the 69 year old yesterday.  He gave his permission for me to post it:

Dear Chris,

I want you to know that I completed the Muncie half ironman Endurathon this past weekend despite high winds, thunderstorms during the entire bike and Indiana heat and winds during the walk/run.  I completed it in 7 hours, 31 minutes—4th in my age group.  I must say my knee is somewhat “sore” today (Monday) 4-5 out of 10 but I am walking, able to operate and fully functional.

I don’t think I could have ever done it without your administrations and help.

Thanks again,


Joseph C. Maroon, M.D.

Enough said.  Here are some stories and other posts on Joe:
