Posterior cruciate ligament (PCL) injuries with grade III laxity suggest lateral structure damage. Combined PCL and posterolateral corner reconstruction effectively restores knee stability.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Knee Biomechanics

Background:

  • Posterior cruciate ligament (PCL) injuries often occur with concurrent damage to the knee's lateral structures.
  • Grade III laxity in PCL injuries is a significant indicator of potential posterolateral corner involvement.
  • Isolated PCL reconstruction may not fully address instability when the posterolateral corner is also compromised.

Purpose of the Study:

  • To describe a surgical technique for posterolateral reconstruction in the knee.
  • To evaluate the efficacy of combined PCL and posterolateral reconstruction for restoring knee stability.
  • To highlight the importance of addressing combined injuries for optimal patient outcomes.

Main Methods:

  • Description of a specific posterolateral reconstruction surgical procedure.

  • Utilizes allograft tissue and interference screw fixation (autograft is an alternative).
  • Performed in conjunction with an intra-articular PCL reconstruction.

    • Main Results:

    • The described posterolateral reconstruction procedure, when combined with PCL reconstruction, successfully restores rotary and posterior knee stability.
    • This combined approach addresses the complex instability associated with concomitant PCL and posterolateral corner injuries.
    • The technique provides a viable surgical option for managing these combined knee ligament injuries.

    Conclusions:

    • Suspect lateral structure compromise in PCL injuries with grade III laxity.
    • Combined PCL and posterolateral reconstruction is essential for restoring stability in these cases.
    • This surgical approach effectively restores both rotary and posterior knee stability.
