    Abstract:
    Major amputations of the lower extremity may be required after trauma and a variety of underlying diseases such as peripheral vascular disease, diabetes, and malignancies. The goal of any major amputation is an optimal functional result with a maximum limb length in combination with optimal wound healing. The preservation of the knee joint is essential for successful rehabilitation, and this is best achieved by the Burgess below-knee amputation (BKA). Whenever a BKA is not possible, the Gritti-Stokes amputation is our first choice. This technique mainly consists of a through-knee amputation with the creation of a pedicled patella flap consisting of the patella, patellar ligament, and overlying soft tissue. After osteotomy of the distal femur and resection of the articular surface of the patella, the anterior flap is rotated in order to cover the femur defect while performing a patellofemoral arthrodesis. The aim of this paper is to describe our surgical technique and experience with GSA and to point out the important steps of this procedure. In conclusion, GSA is an excellent surgical option for patients requiring major lower limb amputations where BKA cannot be considered. Particular attention must be paid to careful preoperative evaluation and optimization of comorbidities. A meticulous surgical technique is warranted, including atraumatic tissue handling and an optimal patellofemoral arthrodesis technique.
