Final answer:
During MPFL reconstruction, the correct positioning of the femoral attachment site of the graft is determined using anatomical landmarks and intraoperative measurements.
Step-by-step explanation:
During MPFL reconstruction, the correct positioning of the femoral attachment site of the graft is crucial for optimal outcomes. To determine the correct positioning, surgeons typically use anatomical landmarks and intraoperative measurements. The most common landmark used is the adductor tubercle, which is located on the femur near the medial epicondyle. The graft is typically attached to the femur just distal to the adductor tubercle. Intraoperative measurements, such as the width of the patella and the patellar height, are also used to ensure accurate placement of the graft attachment site.
