Free-style Approach to the Pedicled Lower Medial Thigh Perforator Flap

Abstract

Summary: Soft tissue reconstruction around joints such as the knee requires a few additional considerations compared with other regions. The overlying skin must be pliable, with adequate distensibility to maintain the range of motion as a hinge joint, and ideally be replaced with “like-for-like” tissue to restore its delicate contour. The advent of perforator flaps has provided reconstructive surgeons with thin, pliable flaps conferring superior aesthetic results, good preservation of joint range of motion, and less donor site morbidity. Utilizing locoregional options also allows replacement with “like-for-like.” We retrospectively reviewed lower medial thigh perforator flaps performed for traumatic and debrided infected knee wounds, using a free-style approach to flap harvest. The described technique was found to be reliable, with consistent anatomy. All flaps survived and successfully covered small- to medium-sized critical defects in healthy individuals and those with multiple comorbidities.
