Bone-Patellar Tendon-Bone Graft

  • Disadvantages
    • Donor site morbidity
      • Knee cap pain
      • Crepitus and tendinitis
      • Quadriceps weakness
    • Rare
      • Patella fractures

Hamstrings Grafts

  • Advantages
    • Less donor site morbidity
      • Decreased knee cap pain
      • Decreased tendinitis
      • Less quadriceps weakness

But Why Sacrifice Hamstrings When…

  • Hamstrings are important rotational and anterior stabilizers of the knee
  • A role similar to the ACL

  • Also known as donor cadaveric grafts
  • As opposed to your own tissue which is known as autografts
