In order to do a pectineal ligament repair, the properitoneal fat must
be swept up off the transversalis fascia covering pectineal ligament.
This also exposes the iliac vessels and the upper end of the femoral
canal. The pectineal ligament is about two centimeters deeper than the
inguinal ligament.
In order to bring the falx back to the pectineal ligament without tension,
a relaxing incision is made in the deep layer of anterior rectus
sheath in the cleft beneath external oblique aponeurosis. The falx
is sutured to pectineal ligament up to the rim of the femoral canal where
a transition stitch makes the jump from the deeper pectineal plane
to the level of the iliopubic tract and inguinal ligament. The remainder
of the suture line is completed as in the iliopubic tract repair.

The "tension-free" prosthetic mesh onlay repair (Lichtenstein)
is done by suturing non-absorbable mesh anteriorly over the inguinal
floor. Tails of mesh are sutured around the cord to create a snug internal
ring. The mesh becomes incorporated by tissue ingrowth.
One other type of open hernia repair, the preperitoneal mesh repair (Stoppa)
has been superseded by the laparoscopic placement of mesh. A hybrid minimally
invasive preperitoneal mesh repair (Kugel) has recently been introduced
which has the advantages of the anterior and posterior approaches without
the disadvantages of large incision and laparoscopic technology.
