To describe a combined anterior cruciate ligament (ACL) and posterolateral corner (PLC) reconstruction technique designed to address technical challenges associated with multiligament knee injuries.
Methods:
A technical reconstruction method is presented using autologous hamstring tendons for ACL reconstruction and the peroneus longus tendon for anatomic PLC reconstruction. The technique employs a single shared femoral tunnel for both the ACL and fibular collateral ligament, aiming to reduce the risk of femoral tunnel convergence and minimize the need for multiple fixation devices.
Results:
The described technique enables anatomic reconstruction of the ACL and key stabilizing structures of the PLC using readily available autologous grafts. The use of a single femoral tunnel simplifies the surgical procedure, decreases the likelihood of tunnel convergence, and reduces implant requirements while maintaining appropriate graft positioning and fixation.
Conclusion:
Combined ACL and PLC reconstruction using hamstring and peroneus longus autografts with a shared femoral tunnel is a feasible and reproducible technique. This approach may simplify complex multiligament reconstructions, reduce surgical morbidity, and provide an effective alternative for restoring knee stability without reliance on multiple femoral tunnels or extensive fixation hardware.
