I have seen this entity in the knee a couple of times without taking notice, interpreted it as some kind of ‘variant’..
This time I know for sure that it has .emerged during the last couple of years in this 65 yo woman. (I doubt it is symptomatic.. her problem is the probably the medial gonarthrosis.)
Does anyone know what this protuberance represent, and does it matter?
(sorry if similar has been posted before)

chapter’s on OA – single or multi volume editions of his textbooks – since
the 1st edition.
So it has been well described on XR long before MRI.
Some folk also describe it as a ‘button osteophyte’ but I much prefer
central or chondral osteophyte.
Cheers,
Rob

The process is beautifully described and illustrated in all Don Resnick’s chapter’s on OA – single or multi volume editions of his textbooks – since the 1st edition.
So it has been well described on XR long before MRI.

osteophyte..
I’m probably the only one in the entire world who didn’t know about this
entity.. and when I am finally able to google the correct string it is
all over the place..
Thank you Eddie, my favourite lecturer Phillip, Byron, Jan, Gustav,
Faraji, Daniel, Sergio, Justin, T Cantarelli, Avneesh, Donald (wow, I’m
starstruck 😀 ) , Robert, Dennis..
Love OCAD. Must do this more often.
And Avneesh, of course you have published an article on the subject, why am
I not surprised ?! Love it 🙂
Kind regards, Kristian
