TKR with correction of hyper extension

Posted by badthumb @badthumb, Apr 13 10:13am

My surgeon (not at Mayo) did my TKR, found & corrected a hyper extension. This recovery has been slower with pain holding on longer than my regular TKR (done at Mayo). Bend reached 136 degrees, I can walk with no issues. The medial side was EXTREMELY sensitive to touch for 8 months and continues to be painful when bent beyond 90 degrees. Medial knee has occasional surges of sharp pain when extended, and random sensitivities and pain under/near medial and lower side of patella. How much of this may be considered "normal" for this type of correction vs TKR alone. I will reach 1 year mark in 60 days.

I had TKR 9/2024. I have hyper extension ever since. Surgeon says it’s a neuro/muscular problem. I had 10 months of PT and resistance strength training for 10 months. Using a metal brace and a walker . Will see a neuro/muscular specialist for EMG etc.
any thoughts?

I am confused by your post. Are you saying that you have had two TKRs done: one at Mayo and one somewhere else? If yes...when was each done. Mayo has been doing minimally invasive surgeries for some time, not traditional ones.

How was each done? What method was used? Did the surgeon in each use a tourniquet? What about alignment?

OR, are you saying that you have had one TKR that was done at Mayo and a revision done somewhere else?

steveinarizona:
I apologize for the confusion.

My right knee had a TKR at Mayo in 2022. The results have been fantastic!

I had my left knee done elsewhere in 2025 (sadly because husband did not want the long drive to Mayo).

The local ortho (also a highly praised physician and facility) found more damage than expected (mentioning a cartilage groove), did a TKR and corrected for hyper extension during the same replacement. His notes did say my patella was thin and he was unable to remove as much as normal.

In my post I was hoping for opinions of others who may have had a similar procedure performed (TKR plus correction of hyper extension) and whether their recovery was different, and how, compared to their regular TKR.

As far as your question about technique, tourniquets, etc., I have no knowledge of procedures used, except that the most recent used robotic assistance. Neither of my replacements were "minimally invasive".
