Application of Superior Lateral Genicular
Artery Perforator Flap for Knee Defects
Introduction
and Objectives
The knee is the human
body’s biggest joint and is susceptible to trauma, severe burn injuries, tumor,
infection, and post-surgical complications, such as hard-wire or prosthesis
exposure. These injuries may result in substantial consequences, such as
tendon, bone, joint, and ligament injuries and exposure of essential
structures. Local flaps, muscle flaps,
perforator flaps, and free tissue transfers have been identified and used for
the soft reconstruction of the knee.
This study aims to
evaluate the use of fasciocutaneous flaps originating from the superior lateral
genicular artery, located on the distal of the thigh, in knee reconstruction.
Materials and Methods
Between 2018 and 2022, this flap was used in 5 patients suitable for these
evaluations. We chose five patients with soft tissue defects around the knee and
reconstructed defects with the SLGP flap.
Results
Two patients had marginal necrosis of the
distal tip of the flap. These patients' marginal flap loss management was with
debridement and primary closure. Primary donor site closure wasn’t possible,
managed with split skin grafts. No late complications were observed in the
donor area or the covered defect site.
Discussion and
Conclusion
The most
important advantage of the superior lateral genicular artery perforator flap
over other options is that it has characteristics similar to the skin of the
knee and knee circumference. Even though a perforator flap that can be obtained
from the superior medial of the knee and is based on the descending genicular
artery has been defined, fasciocutaneous flaps originating from the medial knee
remain thicker than the lateral region.
The superior
lateral genicular artery is reliable with consistent anatomy. Although the need
for grafting of the donor site may develop, the superior lateral genicular
artery perforator flap is a reasonable option for soft tissue defects in the
knee region.
