The suprapatellar bursa is an extension of the joint cavity above the kneecap.
When the septum is incomplete, ie a plica, then the pouch and bursa are effectively the same structure. A complete septum separates the two spaces.
Terminology
The term is generally used interchangeably with suprapatellar pouch, but really it is only when the suprapatellar plica forms a complete septum and splits the pouch in two that a distinct bursa exists. If excessive fluid forms in this bursa it may be called a suprapatellar cyst.

Suprapatellar pouch
