Posterolateral corner knee injuries often accompany cruciate ligament tears, leading to instability. A novel surgical technique using a split Achilles tendon allograft effectively reconstructs these complex injuries, improving outcomes.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Knee Biomechanics

Background:

  • Posterolateral corner injuries frequently occur with cruciate ligament tears, causing significant knee instability (varus, posterior translation, external rotation).
  • Undiagnosed or untreated posterolateral corner injuries can lead to cruciate ligament reconstruction failure.
  • Surgical consensus favors combined reconstruction for posterolateral corner injuries, whether isolated or associated with cruciate ligament tears.

Purpose of the Study:

  • To introduce and describe a novel surgical technique for reconstructing the posterolateral corner of the knee.
  • To address common pitfalls in posterolateral corner reconstruction, including concurrent repair of key structures, isometry restoration, and anatomical repositioning.

Main Methods:

  • A new technique for posterolateral corner reconstruction utilizing a split Achilles tendon allograft is presented.

  • The method focuses on reconstructing the popliteus, popliteofibular ligament, and lateral collateral ligament.
  • Emphasis is placed on achieving isometry of the lateral collateral ligament and accurate popliteus repositioning with secure fixation.

    • Main Results:

    • The described technique allows for concurrent reconstruction of essential posterolateral structures.
    • It aims to restore isometry for the lateral collateral ligament.
    • The method facilitates precise repositioning of the reconstructed popliteus and ensures secure graft fixation.

    Conclusions:

    • The novel split Achilles tendon allograft technique offers a viable solution for complex posterolateral corner knee injuries.
    • This approach addresses critical aspects of reconstruction, potentially improving functional outcomes and reducing revision rates.
    • Concurrent reconstruction of the posterolateral corner with cruciate ligament injuries is recommended for optimal results.
