This an open, uncontrolled multicenter clinical study to assess the safety and performance of the WK-6 surgical mesh in adult patients with unilateral inguinal hernia.

The primary objective is to determine the safety of the WK-6 surgical mesh. Data will be compared retrospectively with published studies on inguinal hernia mesh.

The secondary objectives are to explore the performance of the surgical mesh by measuring the pain pre and post surgery as well as a number of relevant variables for establishing the performance of the mesh. Data will be compared retrospectively with previous studies on inguinal hernia mesh with a follow-up of at least one year.

Primary Outcome Measures:
  • Frequency of Adverse Events or Serious Adverse Events [ Time Frame: 12 months ]
    Safety is assessed by monitoring the incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs) related and unrelated to the mesh and rehabilitation. AEs and SAEs will be collected during surgery and throughout the follow up period. Possible adverse reactions with the use of any prosthesis may include but are not limited to infection, inflammation, extrusion, dhesion, fistula formation, seroma formation, hematoma, and recurrence of the hernia or tissue defect.

Secondary Outcome Measures:
  • Pain [ Time Frame: 12 months ]
    The experienced pain will be measured by an ungraded Visual Analogue Scale (VAS). VAS will be assessed before the surgery and during the follow up period and elucidate the pain experienced during different conditions. A symptoms questionnaire and an analgesics diary will be used to assess the performance of the WK-6 surgical mesh for use in inguinal hernia repair.
