Gastrocnaemius-propeller extended miocutanous flap: a new chimaeric flap for soft tissue reconstruction of the knee.


PURPOSE Soft tissue defects involving the anterior aspect of the knee are a frequent finding in a number of pathological conditions. The aim of this article is to describe a new pedicled flap consisting of a conventional medial gastrocnaemius muscle flap associated with a propeller flap based on a perforator of the medial sural artery. MATERIAL AND METHODS Five males ranging in age between 26 and 72 years underwent a reconstruction of the soft tissue of the knee by means of the described procedure. Three patients sustained complex tissue loss subsequent to high-energy trauma; two losses were due to septic complications after elective knee surgery. RESULTS Four flaps survived allowing adequate proximal tibial metaphysis and patella coverage. One patient underwent early above-the-knee amputation due to life-threatening septicaemia. DISCUSSION The described chimaera flap consists of a medial gastrocnaemius flap with a skin paddle that is elevated on a perforator of the medial sural artery and then rotated according to the propeller flaps' principles. It provides effective coverage of large soft tissue defects of the knee. In the authors' experience, the propeller flap portion proved to be particularly useful to cover the patella, while the muscle flap was used to cover the proximal metaphysis of the tibia and fill the dead space if present.
