Reconstructing complex peripatellar defects using the descending genicular artery perforator flap.

Background: Complex peripatellar defects are commonly reconstructed with free flaps or pedicled muscle flaps, whereas pedicled fasciocutaneous perforator flaps are commonly overlooked. The descending genicular artery perforator (DGAP) flap is a versatile flap that offers thin and pliable tissue that provides ideal 'like with like' peripatellar soft tissue defect reconstruction. This paper aims to demonstrate the safe use of a pedicled fasciocutaneous DGAP flap for extensive traumatic peripatellar defect reconstructions and to exhibit the surgical pearls via a case series.
