Reduced pressure, compression systems and apparatuses for use on joints

A flexible, reduced-pressure dressing assembly for use on

• a patient's joint, the dressing assembly comprising:
• a flexible bolster body having a first side and a second side, the bolster body formed from a bolster material;
• a plurality of flexion joints operable to allow the flexible, reduced-pressure dressing assembly to flex with the patient's joint, wherein the plurality of
• flexion joints comprises a first plurality of bolster modules formed on a first side of the bolster body, a second plurality of bolster modules formed on the second side of the bolster body, each bolster module having a bolster ridge, and wherein each flexion joint of the plurality of flexion joints has a resting
• angle alpha greater than or equal to 60 degrees;
• and a drape extending over the bolster ridges of the first side of the bolster body, wherein the drape is formed from an elastomeric material and is operable to stretch longitudinally at least 80 percent of the drape's un-stretched length.
