A system for providing reduced-pressure treatment to a moveable tissue site, such as a joint, includes a flexible dressing bolster. The flexible dressing bolster has a first side and a second, inward-facing side, and a plurality of flexion joints formed on the flexible dressing bolster. The system further includes a sealing subsystem for providing a fluid seal over the flexible dressing bolster and the patient's epidermis and a reduced-pressure subsystem 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 with folds. Other systems, apparatuses, and methods are presented.

1. 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 offlexion 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 restingangle 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. 2. The flexible, reduced-pressure dressing assembly for use on a patient's joint of claim 1 wherein the bolster body has a first lateral side and a second lateral side; and further comprising a first side recess formed on the first lateral side of the bolster body and a second side recess formed on the second lateral side of the bolster body. 3. The flexible, reduced-pressure dressing assembly for use on a patient's joint of claim 1 wherein the drape is coupled to the first plurality of bolster modules. 4. An apparatus for providing reduced-pressure wound treatment to a tissue site, the apparatus comprising: a flexible dressing bolster having a first surface and a second, inward-facing surface; wherein the flexible dressing bolster includes a plurality of flexion joints formed on said second, inward-facing surface; a drape at least partially covering the flexible dressing bolster; and wherein the drape includes a plurality of drape-extension devices to facilitate bending of the apparatus. 5. The apparatus of claim 4, wherein the drape-extension devices comprise a plurality of folds. 6. The apparatus of claim 4, wherein the drape-extension devices comprise comprises, ridges of additional drape material that provides the ability for the drape to stretch over longer distances. 7. The apparatus of claim 4, wherein the drape includes a drape extension around a perimeter of the drape; further comprising an intermediate drape layer having an aperture; and wherein the drape extension of the drape is coupled to the intermediate drape layer to at least partially enclose the flexible dressing bolster. 8. The apparatus of claim 4, wherein the drape includes a drape extension around a perimeter of the drape;further comprising an intermediate drape layer having an aperture;wherein the drape extension of the drape is coupled to the intermediate drape layer to at least partially enclose the flexible dressing bolster; andwherein the intermediate drape layer has a first side and a second, inward-facing side, and the second side is operable to adhere to the tissue site. 9. The apparatus of claim 5, wherein the plurality of folds are operable to unfold when the flexible dressing bolster is bent. 10. The apparatus of claim 5, wherein the plurality of folds includes at least one lateral fold. 11. The apparatus of claim 5, wherein the drape has a first side and a second, inward-facing side; wherein the drape includes a plurality of bond sites proximate the plurality of folds; and wherein each of the plurality of bond sites adhere to a portion of the drape. 12. The apparatus of claim 5, wherein each of the plurality of folds is formed by looping a portion of the drape. 13. The apparatus of claim 5, wherein the plurality of folds include a first fold and a second fold, wherein the first fold and the second fold each have a longitudinal length, and wherein a distance between the first and second fold exceeds the longitudinal length. 14. The apparatus of claim 5, wherein the plurality of folds include a first fold and a second fold, wherein the first fold and the second fold each have a longitudinal length, and wherein a distance between the first and second fold is substantially equal to the longitudinal length. 15. The apparatus of claim 4, further comprising: a tissue-interface layer disposed between the flexible dressing bolster and the tissue site. 16. The apparatus of claim 4, further comprising: an intermediate drape layer having an aperture;wherein the drape extension of the drape is coupled to the intermediate drape layer to at least partially enclose the flexible dressing bolster;a tissue-interface layer disposed between the flexible dressing bolster and the tissue site; andwherein the tissue-interface layer is at least partially disposed in the aperture of the intermediate drape layer.
