Suprapatellar plica syndrome

Case contributed by Dr Andrew Dixon


Anterior knee pain. ?quadriceps tendinosis

Patient Data

Age: 35
Gender: Female

Fluid within the suprapatellar recess of the knee joint with synovial thickening and hypervascularity indicating synovitis. Unusual morphology of the fluid with the impression of a central septation and mass effect upon the superior aspect of the quadriceps fat pad. 


MRI confirms that the unusual appearance of the suprapatellar pouch of the knee on ultrasound is due to a complete suprapatella plica entrapping fluid, producing localized synovitis and distorting the quadriceps fat pad.  There is minor central quadriceps insertional tendinosis. The superior extent of the synovial abnormality has not been completely imaged. No other significant finding.
