Abstract:
Objective: To investigate the feasibility and effectiveness of the superior lateral genicular artery perforator flap for repairing of soft tissue defects in extremities. Methods: Between September 2010 and October 2017, 11 cases of skin and soft tissue in extremities were repaired with the superior lateral genicular artery perforator flap. There were 10 males and 1 female, with an average age of 37.6 years (range, 6-72 years). The causes of injury were traffic accident in 6 cases, machine injury in 1 case, falling down injury in 1 case, falling from height in 1 case, crushing injury in 1 case, and electric injury in 1 case. The defects located at the forearm in 1 case, knee in 5 cases, popliteal fossa in 2 cases, shank in 1 case, and foot and ankle in 2 cases. The area of the wound ranged from 8.0 cm×4.5 cm to 27.0 cm×8.0 cm. The interval from injury to admission was 6 days on average (range, 3-12 days). The area of perforator flap ranged from 9.0 cm×5.5 cm to 28.0 cm×9.0 cm. There were 8 cases of pedicle flap and 3 cases of free flap. All the donor sites were closed directly. Results: Eight flaps survived without any complications and the donor sites healed by first intention. Two flaps had arterial crisis and 1 flap had venous crisis after operation, and the wounds healed after symptomatic treatment. There was no hematoma and secondary infections in all patients after operation. Ten patients were followed up 2-48 months (mean, 13.1 months). All flaps had satisfied appearance and texture. There was no motion limitations in the hip and knee joints of the operated legs. Conclusion: The superior lateral genicular artery perforator flap not only can be used to repair the soft tissue defect around the knee joint as pedicle flap, but also can be used to repair the forearm and foot skin and soft tissue defects as free flap, which is a feasible way to repair soft tissue defects in extremities.
