A different unhappy triad in the knee: a case of acute simultaneous rupture of Patellar Tendon, Anterior Cruciate Ligament and lateral meniscus treated in one stage and review of literature.

We present a case report of a 43-year-old male patient with simultaneous ruptured of anterior cruciate ligament (ACL), patellar tendon (PT) and lateral meniscus tear, occurred during a tennis match. This combinate tear is not frequent, and literature reports only few cases. Clinical diagnosis can be difficult and the support of MRI and X-Ray is needed.

The Evolgate: a method to improve the pullout strength of interference screws in tibial fixation of anterior cruciate ligament reconstruction with doubled gracilis and semitendinosus tendons.

Purpose: The goal of the study was to investigate the biomechanical properties of a new device for tibial fixation in arthroscopic anterior cruciate ligament reconstruction using doubled semitendinosus and gracilis tendons.

Type Of Study: Biomechanical study.

Methods: This study compares the initial pullout strength, stiffness, and failure modes of 7 pairs of 4-strand human semitendinosus and gracilis grafts fixed to porcine tibias using either the Evolgate (Citieffe, Bologna, Italy) or 1 round threaded titanium interference screw.
