ACL autograft

Hamstrings tendons need to be combined and folded to make the autograft construct.

From where is the autograft taken?

Autograft can be harvested from the patient's own hamstrings tendons, the patellar tendon, the quads tendon or in some cases also the iliotibial band.

Surgeons probably have the most experience with harvesting the graft from the patellar tendon.

• Quote from peer-reviewed paper:

  "....there is no consensus to what the best graft option is to replace the injured ACL....[but the] decision must be made prior to surgery regarding the type of graft that will be used...."

The biological advantages of autograft

Although harvesting autograft material from the patient leaves them with a harvest site that may be a bit compromising, autograft has the advantages of being genetically identical to the tissue it is replacing.

Also it is not treated with any chemicals or physical processes and it is warm and fresh. The new ligament construct will still need, however, to re-establish a blood supply and re-fashion itself to fit its new purpose.

  "....A third option is the quadriceps tendon (QT), which can include a bone block from the patella (BQT)."
