Ligament augmentation devices (LAD) do not improve outcomes for anterior cruciate ligament (ACL) reconstruction and may increase risks. Current evidence does not support routine use of LAD in ACL repair with biological grafts.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Sports Medicine

Background:

  • Anterior cruciate ligament (ACL) injuries are common, often leading to knee instability despite rehabilitation.
  • Reconstruction methods utilize autografts, allografts, or prosthetic materials.
  • Ligament augmentation devices (LAD) were developed to support biological grafts during their healing phase.

Observation:

  • LADs are designed to protect biological grafts during initial healing.
  • Experimental studies show LADs can share loads and are stronger than biological grafts.
  • Clinical use of LADs has not demonstrated significant advantages in ACL reconstruction.

Findings:

  • LADs can provoke inflammatory reactions and delay graft maturation in humans.

  • No significant benefits observed when using LADs with patellar tendon or hamstring autografts for ACL reconstruction.
  • Limited evidence for LAD use in posterior cruciate ligament reconstruction, with no clear advantages.

    • Implications:

    • LAD insertion introduces foreign material, increasing risks of synovitis, effusions, and infection.
    • Current evidence does not support the routine use of LAD in uncomplicated ACL reconstructions.
    • Further research is needed to clarify the role, if any, of LADs in specific ligament reconstruction scenarios.
