1. A system for applying negative pressure to a joint positioned in a treatment area, the system comprising:
a negative pressure dressing comprising:
a compressive layer having a thickness between a first surface and a second, treatment area-facing surface, the compressive layer comprising:
a first elongated portion configured to be positioned proximate the joint, the first elongated portion including a first end and a second end;
a second elongated portion spaced from the first elongated portion and configured to be positioned proximate the joint, the second elongated portion including a first end and a second end;
an interconnecting portion extending between the first elongated portion and the second elongated portion, the interconnecting portion configured to overlie at least a portion of the joint; and
a plurality of channels having a depth less than the thickness of the compressive layer formed in the first surface of the compressive layer and extending proximate the second surface of the compressive layer, the plurality of channels formed in at least one of the first end and the second end of the first elongated portion and at least one of the first end and the second end of the second elongated portion;
a plurality of ribs formed between adjacent channels of the plurality of channels, wherein a spacing between adjacent ribs of the plurality of ribs increases in a laterally inward direction; and
a sealing layer configured to form a seal around a perimeter of the negative pressure dressing.
