From my research when Dr's say the implant is good it probably is. For whatever reason orthopedic Drs will not look for other issues other than the implant. Most likely mine is caused by soft tissue or ligaments but how do I know until I find a Dr that will go the extra effort. Good luck with Mayo hopefully they will help you. My request was not accepted. I have found good information on You Tube videos of other causes for pain but still need a diagnosis.
