I've posted "my story" elsewhere, however felt compelled to comment here: Since bone can take up to 2 years to heal and adhere to the insert I felt that walking and not running for that length of time would put me in the "least likely to need revision surgery" category. I walked, walked, walked. 1st a mile then a few, then 5 &10 + mile hikes after 3-4 months out. Next 15 & 20 mile hikes 6 mos out. @ 1 year I was at the top of Kilimanjaro happy and well. @ 2 years I started jogging. 1 mile then a few a couple of days a week. Now, 2.5 years out I run 2-4 miles two to 3 times a week and hike Hills (for those who know- Koko Crater- and the likes on Oahu) regularly. 6mph jogger, so no speed demon. 160 lb, 5'10" 64 yrs and keeping a healthy lifestyle. I have been given my mobility back and so I chose a conservative path back to where I am now. Recently finished a 1/2 marathon. Ecstatic Doctors can work such magic!
Good luck and take your time, you have the rest of your life.
