1 Tibial Inlay Technique Using Hamstring Graft for Posterior Cruciate Ligament Reconstruction and Remnant Revision  Wiroon Laupattarakasem, M.D., Manusak Boonard, M.D., Pat Laupattarakasem, M.D., Weerachai Kosuwon, M.D.  Arthroscopy Techniques  Volume 2, Issue 1, Pages e1-e7 (February 2013) DOI: /j.eats Copyright © 2013 Arthroscopy Association of North America Terms and Conditions

2 Fig 1 Bird’s-eye view showing the scenario for patient setup during the open popliteal approach for the tibial inlay technique. The patient is placed supine on an operating table equipped with 2 modular leg plates. The leg plate supporting the operative knee is dropped down, and the leg is transferred onto a work table with the hip fully externally rotated, flexed, and abducted. The other leg plate is abducted to provide more room for the surgeon to sit between the 2 lower limbs. The operating table is side tilted to further open up the popliteal area.

3 Fig 2 Outline for the harvest of the unicortical bone block from the footprint area of the PCL at the tibia. This material will subsequently function as the bone washer. The black dot represents the central drill hole for the cancellous screw.

4 Fig 3 The hamstring graft bundles are slung over the cancellous screw shaft for the tibial inlay technique using this graft for PCL reconstruction. The affixed sutures leading the free ends of the graft have been introduced into the medial femoral tunnel from the posterior compartment. The bone washer will then be driven together with the commercial washer to compress on the transfixed hamstring graft against the bone socket bed.

5 Fig 4 The peeled-off remnant fibers of the PCL and/or MFL with a thin layer of the attaching bone plate at the tibia are augmented with sutures. The remnant is pulled taut against the screw shaft and behind the hamstring graft bundles and will then be compressed together with the hamstring graft loop under the bone washer. It should be noted that the PCL/MFL remnant remains with significant integrity at the femur. The free ends of the hamstring graft have passed through the medial femoral tunnel.

6 Fig 5 Flow diagram showing the steps of the tibial inlay technique using semitendinosus (SMT) and gracilis (G) tendon graft for PCL reconstruction and PCL and/or MFL remnant revision to be fixed under tension at the tibia using a bone washer. Symbols with a solid arrow indicate activity performed by the surgeon; symbols with a dashed arrow indicate activity optionally performed by the assistant.
