Let me reverse the Nike Statement here to say JUST DONT DO IT. And I am not being flippant here. Most definitely worst decision of my life. 14 years of pain much worse than my original condition.
And the docs? They shrug their shoulders and disappear- because they know revisions are even less likely to work. I have seen experts from 5 states and NOBODY wants to go back in there.
Keep your original parts and try to deal with it. You have at best a 50% chance for success regardless of the false promotions from manufacturers and docs.
You will most likely not have results you hope for and the post-op recovery period is extremely long and painful.
For background I am , or was, an excellent athlete, doing tri’s, long distance cycling and tennis and basketball. Since the surgery I cannot walk without pain to the refrigerator - yet I can bike 40 miles- biking puts less stress on my on knee and I can compensate with good leg.
But even on bike it’s painful and I just grit my teeth and deal with it- as I swear at myself for volunteering for this horrible surgery…..
