alternative term for Jägerhut-patella

[Guest guest]

Hello all,

A " Jägerhut-Patella " is a form of patella dysplasia, where the medial part

of the trochlea of femur is (practically) absent, and the patella is formed

accordingly (supposedly like a 'huntsman's hat', well, a German one;).

Could anyone provide me with some 'official' term for this kind of patella

dysplasia, preferably in Latin and/or English and/or Dutch?

Kind regards & many thanks in advance,

Albert

Hello Albert,

The kneecap certainly seems to be a Germanic specialist field!

Wiberg is your man - he is responsible for a classification of

patellar " shapes " . (There is also a doctor Baumgartl with his own

classification.)

I found this American article, which refers to the hunter's cap:

http://www.kneehippain.com/patient/pain/abnormalities.html

" When viewed in axial cross-section, the medial bony facet can be

excessively small, there may be no separate medial and lateral bony

facet, the patella may look like a hunter's cap (as described by

Wiberg) or a pebble - to name but a few abnormalities. "

Apart from that, I have found plenty of references to patellar or

femoral trochlear dysplasia, but there is nothing particularly

specific about abnormal patellar shapes.

Good luck!

Sue
