Adult tibial eminence fracture fixation: arthroscopic procedure using K-wire folded fixation.

The purpose of this article is to describe a new and simple technique for arthroscopic fixation of tibial intercondylar eminence avulsion fractures using folded surgical pin. This technique allows reduction and fixation of the bone fragment without using special equipment. After standard arthroscopic procedure to explore the knee and to remove fracture debris and blood clot, the bone block is reduced and advanced with the spike of the anterior cruciate ligament tibial drill guide. A 1.8-mm K-wire is drilled through the guide from the proximal tibia into the reduced fragment. It is bent on its end into the joint with a strong needle case. The K-wire is then pulled back until good fragment compression to the tibia appears with the wire starting unbending. Next, the other side is bent on the anterior tibial cortex and cut. This arthroscopic fixation allows elastic compression fragment stabilization that authorizes early weight bearing and rehabilitation programs. The material is extracted by traction after 6 months.
