I had my kneecap replaced about two months ago due to a football injury that happened almost 4 years ago.
At the time, they told me the best they could do was remove a tendon in my knee and hope my knee would work.
Well it worked okay, but I still had problems from my kneecap.
So I finally decided medical expertise had to advance some in the past four years,
When I got to the doctor, they told me that it would easily be fixed with a replaced kneecap.
OT:
You should probably have a medical examiner look at it and suggest what to do, in the past 12 years you'd be supprised how many medical advancements they've made.
