This is interesting. The extra bone is found in 39% of people, if what I read is correct.
I think any good surgeon would know this and not misdiagnose as a baker's cyst or loose body in the knee capsule. These likely would only be seen on a lateral X-ray. I don't know if the TKR would cause the labella bone to cause pain or aggravation. It certainly won't be helped by pain killers, NSAIDs, patches and gels.
If I were in this situation I'd ask if removing the small bone would help. Should be able to be removed with a scope, I think.

heyjo,
I am proof that a TKR can cause a fabella bone to cause horrible pain.
Fabella syndrome is a rare but relevant cause of pain post-total knee arthroplasty (TKA) due to mechanical irritation of the posterolateral tissues of the knee1234. The symptoms of fabella syndrome are posterolateral pain and a catching sensation (or clicking sound) with knee flexion14. The fabella can also get in the way of knee replacement surgery and cause pain and discomfort on its own5.
