Historically, hernias were repaired using "primary suture repair," where the edges of the defect were simply pulled together and sewn. This created high tension on the tissue, often leading to the sutures tearing through and the hernia recurring.

The Lichtenstein Revolution

The modern standard of care is the "tension-free" repair, popularized by Dr. Irving Lichtenstein. This method involves placing a piece of prosthetic mesh over the defect. Instead of pulling tissue together, the mesh acts as a bridge or scaffold. This approach has reduced the recurrence rate for inguinal hernias from over 10% to less than 1%.
