Concomitant Anatomic PCL and FCL Reconstructions With Partial Lateral Meniscectomy.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanics

Background:

• Fibular collateral ligament (FCL) injuries often occur with multiligament knee injuries, causing significant instability.
• Grade 3 posterior cruciate ligament (PCL) tears disrupt knee biomechanics and increase osteoarthritis risk.
• Concomitant FCL and PCL reconstruction is crucial for reducing knee laxity and optimizing function.

Purpose of the Study:

• To describe the surgical technique for combined anatomic FCL and PCL reconstruction.
• To evaluate the clinical outcomes and biomechanical benefits of this combined reconstruction.

Main Methods:

• Stepwise surgical approach involving open and arthroscopic techniques.
• Lateral approach with peroneal neurolysis, FCL tunnel preparation, and autograft harvest.
• Intra-articular work including PCL tunnel preparation and graft fixation in a specific order.

Main Results:

• Anatomic FCL reconstruction in multiligament injuries improves patient outcomes.
• Studies show significant improvements in functional scores and reduced gapping after FCL reconstruction.
• Anatomic double-bundle PCL reconstruction also demonstrates significant functional and objective outcome improvements.

Conclusions:

• Anatomic FCL and PCL reconstructions effectively restore native knee stability.
• These techniques provide superior clinical outcomes compared to nonanatomic reconstructions.
