Medial patella plica syndrome

Case contributed by Henry Knipe
Diagnosis almost certain

Presentation

Medial knee pain.

Patient Data

Age: 15 years
Gender: Female
mri

Thickened medial patellar synovial plica with a partial thickness chondral fissure of the adjacent medial patellar facet.

Remainder of the study is normal. 

Case Discussion

Thickened medial patellar synovial plica are commonly asymptomatic but a good clue on MRI as to whether they are symptomatic is chondromalacia or the adjacent medial patellar facet. In this case, there is no alternative explanation for medial knee pain.
