Introduction:
Surgical defects of the popliteal fossa pose a reconstructive challenge to the surgeon, given the intimate relationship of this area with the knee joint and underlying vital neuro-vasculature.
Case Presentation:
An 88-year-old woman was treated for a biopsy proven invasive squamous cell carcinoma of the right popliteal fossa with Mohs micrographic surgery. The resultant defect (4.5 × 4.3 cm) was repaired using a random patterned bilobed flap with an undersized secondary lobe and porcine xenograft with excellent functional and cosmetic outcome.
Discussion:
Numerous approaches to reconstruction of the popliteal fossa have been proposed, including primary closure, secondary intent healing, skin grafting, random flaps, muscle flaps, fasciocutaneous flaps, freeflaps, and tissue expansion. Sub-optimal repair of the popliteal fossa can reduce mobility of the knee joint, carry a high risk of wound dehiscence and may result in significant scarring. Here, we present the use of a bilobed flap with an undersized secondary lobe, in a patient with limited tissue laxity, for the repair of the popliteal fossa.
Conclusion:
Utilizing a random pattern bilobed flap with an undersized secondary lobe is an excellent alternative for the repair of moderate sized popliteal fossa defects.
