Anatomical Repair With Achilles Tendon Allograft Augmentation for Distal Medial Collateral Ligament Ruptures

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanical Engineering

Background:

• Distal medial collateral ligament (MCL) ruptures can cause significant knee instability, particularly in athletes.
• High physical demands necessitate robust surgical solutions for MCL injuries.
• Existing techniques may not fully address the complex biomechanics of distal MCL avulsions.

Purpose of the Study:

• To describe a novel anatomical surgical technique for distal MCL rupture repair.
• To augment the repair using an Achilles tendon allograft for enhanced stability.
• To provide a reinforced anatomical solution for valgus instability in distal MCL tears.

Main Methods:

• Anatomical repair of distal MCL rupture utilizing a distal tibial anchor.
• Augmentation of the MCL with an Achilles tendon allograft, including a proximal bone block.
• Fixation of the allograft using an interference screw and continuous suturing techniques.
• Consideration of MCL axial traction and posterior oblique ligament fiber orientations during repair.

Main Results:

• The described technique provides a reinforced anatomical repair for distal MCL ruptures.
• The augmentation aims to effectively control valgus instability.
• The procedure addresses the biomechanical complexities of distal MCL avulsions.

Conclusions:

• This anatomical MCL repair and augmentation technique offers a reinforced solution for distal ruptures.
• The method is designed to restore stability and function in athletes with high physical demands.
• The technique considers crucial anatomical and biomechanical factors for successful outcomes.
