Knee and Ankle Reconstruction With Reverse Anterolateral Thigh and Free Anterolateral Thigh Flap From One Donor Site.

Traditionally, the anterolateral thigh (ALT) free flap is used in distal lower extremity reconstruction. Reverse ALT flap has become one of the most popular choices for knee joint soft tissue defects. A 53-year-old man sustained a degloving injury in the right lateral side of the lower extremity from the lateral malleolar area to the knee joint area. The contamination was severe, necessitating serial debridement and negative pressure wound therapy. After 4 weeks, no more soft tissue necrosis was evident. No more microorganism growth was confirmed by swab culture. ALT free flap using proximal perforator was planned for lateral malleolar area reconstruction and reverse ALT flap using distal perforator was planned to cover knee joint after confirming the pedicle length was sufficient for simultaneous knee and lateral malleolar area reconstruction.
