Video Summary - Anatomic Posterolateral Corner Reconstruction Using Single Graft Plus Adjustable-Loop Suspensory...

The video demonstrates a surgical technique for anatomic posterolateral corner reconstruction of the knee using a single graft and an adjustable-loop suspensory fixation device. This method allows for differential tensioning of the grafts involved in the reconstruction.

Key Scientific Concepts and Methodology:

Surgical Procedure Overview:
- Examination under anesthesia to confirm the presence of a posterolateral corner injury.
- Harvesting of the semitendinosus autograft through an oblique incision.
- Creation of fibula and tibial tunnels for graft placement.
Step-by-Step Methodology:
- Incision and Harvesting:
  - Make an oblique incision for autograft harvesting.
  - Develop full thickness subcutaneous flaps.
- Nerve Identification:
  - Perform common peroneal nerve neuralysis.
- Tunnels Creation:
  - Create fibula tunnel using a base pin and a 6mm drill.
  - Create tibial tunnel starting medial to the tibial tubercle using a 7-7.5mm drill.
- Graft Passage and Fixation:
  - Pass a shuttle suture through the tibial tunnel.
  - Create femoral and tibial ACL tunnels arthroscopically.
  - Drill popliteus and fibular collateral ligament (FCL) tunnels.
  - Fixate the grafts using interference screws.
- Adjustable Loop Mechanism:
  - Use an adjustable loop device to allow differential tensioning of the popliteal fibula ligament and FCL grafts.
- Final Steps:
  - Repair biceps avulsion using high-strength sutures.
  - Assess final construct and tension adjustments.
