Radiographic visualization of patellar tendon grafts for the reconstruction of the anterior cruciate ligament.

Abstract

The new biodegradable interference screws offer very many advantages for anterior cruciate ligament replacement with patellar tendon. However, their radiolucency makes it impossible to identify the anchorage sites. We describe an imaging technique of the plasty and its anchorage sites by means of a radiopaque contrast that is commonly used in radiology (Iopamidol; Bracco, Milan, Italy). It is an easy technique that does not extend the time of surgery, it is harmless, and allows us to identify malpositioning or impingement of the plasty.
