Rectus femoris branch: an alternative blood supply for a distally based anterolateral thigh flap

Successful raising of a distally-based anterolateral thigh (dALT) flap mainly depends on a well-developed lateral circumflex femoral artery (LCFA) descending branch and an intact vascular connection between the descending branch and the vascular network of the knee. However, in some clinical scenarios, the descending branch is hypoplastic or the vascular connection of the knee is compromised. We present six cases of using dALT flaps in soft tissue defect reconstruction of the knee with either of the above-mentioned conditions.
