My TKR 12/23 did not provide a good result.

Many months of severe pain along the lateral side walking and stairs were basically impossible.

My surgeon was not helpful (read: loser) and I fired him.

Four opinions from well qualified surgeons (UCSF, STANFORD , etc) diagnosed mid flexion instability.
(Research this if you think this may be your problem. It is an area that knee surgeons debate as it is not completely understood.
There is a ‘gap’ in the knee /implant that is too large allowing it to ‘slide’ around. Not good.

My first revision to correct this was to increase the size of the spacer /insert to tighten up the knee.
I knew this was a 50:50 gamble and it did not help. ( the recovery was very quick which was an upside)
The second revision 4/26 resolved the severe lateral pain but I don’t think my knee will ever be right or pain free.

Recommend

Do some research /reading so you can ask good questions; when you find a well qualified surgeon who will listen to and work with you.
Good luck
