A system (10) for providing reduced-pressure treatment to a moveable tissue site, such as a joint (18), includes a flexible dressing bolster (32). The flexible dressing bolster has a first side and a second, inward-facing side (36), and a plurality of flexion joints (40) formed on the flexible dressing bolster. The system further includes a sealing subsystem (60) for providing a fluid seal over the flexible dressing bolster and the patients epidermis and a reduced-pressure subsystem (80) for delivering a reduced pressure to the sealing subsystem. The sealing subsystem and reduced-pressure subsystem are operable to deliver a reduced pressure to the moveable tissue site. The flexible dressing bolster is operable to allow articulation or movement of the moveable tissue site. The sealing subsystem may include a drape (62) with folds. Other systems, apparatuses, and methods are presented.
