Introduction:

Medial Collateral Ligament (LCM) instability is associated with multi-ligamentary lesions. There are several procedures for the reconstruction of MCL, we present a percutaneous technique of augmentation. Our goal is to describe a new technique of reconstruction of the LCM by grafting and fixing with biocomposite screws.

Material and methods:

We present the technique in a total of 21 consecutive patients with MCL injury operated in the period of December 2011 to October 2014. Reconstruction of MCL was performed with long, tibial or long hallux tendon allografts in 18 patients and only one patient was used autograft. Eighteen of the 20 patients had associated lesions: 5 with medial meniscus injury, 8 with anterior cruciate ligament injury, (ACL), 8 with condral injury and 1 with lateral meniscus injury.

Conclusion:

The surgical technique presented is simple to perform, without damage to other structures and with a strong fixation.
