Abstract

Partite patella is a known cause of anterior knee pain, especially in adolescents and young males, although most patients are asymptomatic. Symptomatic partite patella is usually revealed on magnetic resonance imaging (MRI) as bone marrow edema within the opposing bone fragments. We present a case of unusual bilateral symptomatic multipartite patella in an adult who presented with quadriceps fat pad edema and mass effect as well as slightly edematous signal changes within the bone fragments on MRI. This case indicates that symptomatic partite patella can also present with edema-like imaging findings in the adjacent soft tissue due to chronic mechanical irritation.

Highlights

Bipartite or multipartite patella is a developmental variant resulting from the failure of the secondary ossification centers to fuse with the main body of the patella
quadriceps (suprapatellar) fat pad (QFP) edema or impingement syndrome, which may be associated with anterior knee pain, is an inflammatory process within the quadriceps fat pad and may be analogous to Hoffa’s disease of the infrapatellar fat pad [4,5]
We describe an unusual case of symptomatic multipartite patella, who presented with slightly edematous signal alterations within the bone fragments along with QFP edema with mass effect, both diagnosed on magnetic resonance imaging (MRI)
