1. A buttress assembly for reinforcing tissue layers joined by surgical stapling, wherein the buttress assembly comprises:
(a) a laminated base material comprising:
(i) a knitted textile mesh layer comprising an absorbable synthetic material, the knitted textile mesh layer comprising a first mesh surface and a second mesh surface, wherein the first mesh surface is configured to contact at least one of the tissue layers joined by the surgical stapling,
(ii) a first film layer comprising a first film surface and a second film surface, wherein the first film surface contacts the second mesh surface of the knitted textile mesh layer, wherein the first film layer is configured as an adhesive layer, and
(iii) a second film layer comprising a third film surface and a fourth film surface, wherein the third film surface contacts the second film surface of the first film layer, wherein the fourth film surface is configured to face away from the tissue layers joined by the surgical stapling, wherein the second film layer is configured as an adhesion barrier to prevent tissue from adhering to the fourth film surface; and
(b) an adhesive located on the fourth film surface of the second film layer, wherein the adhesive is configured to provide releasable adhesion of the buttress assembly with an end effector of a surgical stapler,
wherein the knitted textile mesh layer defines a knit pattern, wherein the knit pattern is oriented obliquely relative to a longitudinal axis of the buttress assembly.
