The superior lateral genicular artery flap for reconstruction of knee and proximal
leg defects
Reconstruction of defects around the knee region requires thin and pliable skin. The
superior lateral genicular artery (SLGA) flap provides an excellent alternative to
muscle-based flaps. The anatomy and the surgical techniques of the SLGA flap were
reviewed and the results of cases using the SLGA flap for coverage of knee and proximal
leg defects were analyzed. SLGA flaps were performed in two cases and followed up
for at least 6 months. Twelve articles on the use of the SLGA flap were also identified.
A review of 39 cases showed that the mean diameter of the perforator supplying the
skin of the flap was 1.04 mm, while the mean diameter of the SLGA at its origin was
1.78 mm. The mean length of the pedicle measured from the origin of the popliteal
artery was 7.44 cm. The average dimensions of the flap were 14.8 × 6.6 cm with primary
closure of the donor site in 61.5% of cases. Of these cases, 38.5% were due to trauma,
23.1% were post-burn complications, 12.8% were defects after resection of tumors,
and 10.3% were for ulcers post-bursectomy. The most common complication was flap tip
necrosis. All studies reported favorable outcomes with complete wound healing.
