Reconstruction of Broad Soft Tissue Defect around Knee with Combined Perforator Flaps

Abstract

Perforator flaps have been commonly used in reconstruction of soft tissue defects nowadays, however, it is very important to apply them properly according to the characteristics of recipient site. Since there is no universal flap appropriate to various types of defects, there have been a number of researches to apply appropriate perforator flaps suitable to recipient sites. Recently, achievements have been made by applying chimeric flaps based on perforators from a source artery and combined flaps based on perforators from different source arteries. For examples, combined flaps of deep femoral perforator and gracilis perforator, lateral circumflex femoral artery and tensor fascia lata perforator and lateral vastus muscle and anterior, lateral thigh perforator have been suggested in the literatures. It is a key point to use appropriate perforator flap minimizing donor site morbidity according to the location and size of defects. We are describing a case of covering a soft tissue defect at the knee with combination of medial sural artery perforator flap and medial vastus medialis artery perforator flap.
