Area of Science:

Orthopedic surgery
Knee biomechanics
Sports medicine

Background:

The posterolateral corner (PLC) is vital for knee stability, especially with anterior cruciate ligament (ACL) deficiency.
Understanding PLC injuries is increasingly important in managing knee instability.

Purpose of the Study:

To review current concepts of PLC injuries.
To discuss the role of the PLC in ACL-deficient and ACL-reconstructed knees.

Main Methods:

Review of recent literature on PLC injuries and their management.
Analysis of surgical techniques for combined ACL and PLC reconstruction.

Main Results:

Single-staged, combined reconstruction is the optimal approach.
Successful outcomes reported in over 90% of patients undergoing reconstruction.
Techniques to avoid tunnel collision during multiligament reconstruction are highlighted.

Conclusions:

Simultaneous treatment of concomitant PLC and ACL injuries is essential.
Thorough understanding of local anatomy, diagnostic methods, and surgical techniques is critical for successful clinical outcomes.
