Abstract

Background

The first description of local fascio-cutaneous flaps used for the coverage of soft tissue defects of the limbs originates from the 1980s. Over the years, this technique has advanced, and in the meantime, a sub-group of flaps named perforator-based propeller flaps has gained increased attention. In our study, we aimed to demonstrate our experience of operating surgeries with perforator-based propeller flaps and to compare this technique with other flap techniques, which are to reconstruct tissue defects of the knee, lower leg, and foot.

Methods

A systematic retrospective search for flap procedures for defect reconstructions in the knee, lower leg, and foot from our database was performed. All data between January 2010 and August 2018 were considered. We identified 56 procedures performed on 14 female and 42 male patients with the mean age of 54.13 years. Reconstruction procedures consisted of 34 free flaps, 14 perforator-based propeller flaps, and eight other perforator-based flaps. Compared to free flaps, the perforator-based propeller flaps had shorter surgery duration by 46.6% (p < 0.0001) and the complication rate in the cases of perforator-based propeller flaps was reduced by 31.14% (p = 0.0315). Furthermore, the operations carried out with perforator-based propeller flaps resulted in a significantly lower rate of revisions by 36.03% (p = 0.0204), compared to those with free flaps. The majority of the donor sites of free flaps were self-closing with the direct suture (p = 0.004).

Conclusions

Based on our findings, we can propose the applicability of perforator-based flaps in treating defects of the knee, lower leg, and foot. With a correct indication, perforator-based propeller flap represents a promising alternative to free flaps, with its significantly shorter surgery duration, lower complications rate, and lower revision rate. However, both techniques of the free flap transfer and the transfer of local pedicle-based flap possess their advantages and disadvantages. Therefore, it is hard to define which microsurgical technique is exclusive in treating lower leg defects.
