- The normal supra patellar plica is not continuous.
 - There is a gap in it ( fenestration) which allows fluid to circulate freely in the SP bursa above and below the plica.
- At times the SP Plica is continuous with no gap.
 - Normally we probably wouldn't notice it when reporting and it wouldn't really matter.
 - However…
 - If the SP plica is not fenestrated and there is a haemarthrosis or lipo haemarthrosis.
 - We may get the haemathrosis/ fat signal only in one section of the bursa.
- If you see differential signal in separate parts of the suprapatellar bursa. Â
- This is an indication of a continuous SP Plica.
