Posterolateral Corner Reconstruction of the Knee Using Gracilis Autograft and Biceps Femoris

We introduce our technique for posterolateral corner reconstruction, which is based on the principle described in Arciero's technique for anatomic reconstruction of lateral collateral ligament (LCL) and popliteofibular ligament (PFL) to gain static stability in varus strain and external rotation. This technique uses a doubled gracilis autograft to reconstruct the PFL and a split biceps tendon transfer to reconstruct the LCL. Using this technique an anatomical LCL and PFL reconstruction can be performed in combination with anterior cruciate ligament or posterior cruciate ligament reconstruction without contralateral graft harvest or allograft. The technique also enables an isolated reconstruction of LCL or PFL when required and can be performed to augment an acute repair.
