title: Anterior cruciate ligament revision of a relatively new implant system.
abstract: Cayenne AperFix (Cayenne Medical, Inc, Scottsdale, Arizona) is a relatively new implant used in anterior cruciate ligament (ACL) reconstruction. To date, there have been more than 4500 primary reconstructions performed using the device, and removal of the implant during revision surgery has not been discussed in any published literature. The focal point of the procedure involves removing the center screw within the femoral component, followed by using a core reamer to extract the entire device, leaving behind a femoral tunnel with no defects that can accept a new graft. We present the case of failed primary ACL reconstruction in a 23-year-old man due to a single traumatic event. We discuss the technical challenges associated with this implant as well as the technique used for removal.
