Medial aspect of femoral notch in right knee demonstrating sequence of double-bundle posterior cruciate ligament reconstruction. A, Guide pin is inserted (through an 11-mm reamer between trochlear point and medial arch point, adjacent to cartilage) to re-create anterolateral bundle (ALB). B, An 11-mm diameter closed socket tunnel is reamed to depth of 24 mm for ALB. Posteromedial bundle (PMB) attachment is reproduced next, approximately 5 mm posterior to edge of articular cartilage of medial femoral condyle and distal to medial arch point (also with help of 7-mm reamer placed in medial wall to assess for final position). C, Closed socket tunnel is reamed to depth of 25 mm for second tunnel (PMB). Of note, bone bridge of 2 mm should always be present between tunnels. SEE TECHNIQUE 51.26.
