“…Farrow and Parker (21) evaluated the risk of injury to these structures, except for the genicular artery, in cadavers, and drilled the femoral tunnel by means of knee arthrotomy, using bone structures as the reference points for standardized placement of guidewires with the knee flexed at 90 degrees, in a position that was slightly lateral to the medial femoral condyle and slightly above the anterior cornu of the medial meniscus. They concluded that the femoral tunnel should be drilled with the knee flexed at a minimum of 110 degrees, in order to diminish the risk of injury to lateral structures.…”
