Arthroscopic fixation of the fractures of the intercondylar eminence via transquadricipital tendinous portal.

Abstract

We describe a new technique for arthroscopic reduction and internal fixation of fractures of the intercondylar eminence of the tibia. In this technique cannulated screws are placed through a new portal (transquadricipital tendinous) instead of anteromedial arthroscopic portal. Twelve patients who were treated with this technique for displaced types II and III fractures of the intercondylar eminence of the tibia were reviewed after a mean of 49 months. At follow-up all patients had excellent or good results, without any case of nonunion of the fracture or related complications, such as functional instability. Placement of cannulated screws through transquadricipital tendinous portal achieves fragment reduction easily, provides rigid fixation while avoiding arthrotomy, allowing early mobilization and return to activity.
