Claim:
1. A system for applying a treatment to a defect in a first bone or a second bone of two bones forming a joint, the system comprising: a reduced-pressure source for providing a reduced pressure; a positive-pressure source for providing a positive pressure; a bladder formed of (i) a reduced-pressure chamber formed by flexible walls having an opening adapted to substantially surround the defect when positioned against the first bone and having a port in fluid communication with the reduced-pressure source; and (ii) a bracing chamber formed by flexible walls and adapted to be positioned against the second bone and having a port in fluid communication with the positive-pressure source for providing positive pressure to prevent the bracing chamber from collapsing when positive pressure is provided thereto; wherein a portion of the walls of each of the reduced-pressure chamber and the bracing chamber form an interior wall of the bladder; and a manifold disposed within the reduced-pressure chamber between the interior wall and the opening in the reduced-pressure chamber, and formed of a porous material adapted to distribute reduced pressure to the defect and provide structural support between the first bone and the interior wall to prevent the reduced-pressure chamber from collapsing when reduced pressure is provided thereto.
