Table 4 Essential properties of hernia meshes used for groin and abdominal wall hernia repair
Tensile strength (abdominal wall)22 N/cm (cranial/caudal )
32 N/cm (lateral)
Tensile strength (groin)16 N/cm
OrientationNo specific orientation for meshes with isotropic properties
For meshes with anisotropic properties: orientation in the appropriate direction to match the physiological stretchability
Pore sizeDepending on the used raw material and the foreign body reaction, respectively. To achieve a high effective porosity: for PP meshes a pore size ≥ 1000 µm should be used; for PVDF meshes a pore size ≥ 600 µm should be used
