*2.2. Patient Positioning*

After the induction of general anesthesia, the surgery was performed with the patient in the prone position, with the hip and knee at 20 and 30 degrees of flexion, respectively (Figure 2a). Previously, and in order to center the incision, we identified the stumps of the conjoined tendon (Biceps and semitendinosus) and SMT stumps with the aid of US and MRI (Figure 2b). In our patient, the distance between the ischial tuberosity and the gluteus fold was 3 cm, whereas the joint tendon and SMT were 7 and 10 cm away from the ischial tuberosity, respectively. Once the sterile prepping and draping were completed, the entire extremity was draped so that we could manipulate the hip and knee joints during the surgery to assess and adjust the graft tensioning.
