Yeah find a guy who specializes in revisions. And these need not be revisions to a TKR. It can be a revision to a partial KR, or in my case, a piece of titanium that was placed where my left medial meniscus used to be. I would think that if someone participated in impact sports after a TKR, the part most likely to be damaged would be the prosthesis that replaced the meniscus. This is made out of a very hard plastic, and so much easier to damage than titanium prostheses.

I don't know what qualifies a surgeon as a specialist in revision surgery, but they can be found.

Finally, if you're researching new surgeons, I suggest a Dr. who has a degree from a well-known medical school or college, as well as a residency at a place like Mayo or Cleveland Clinic.

All the best to you! Joe
