Cayenne Medical, Inc., announced in a press release that a new independent clinical study published in the February 2010 issue of Orthopedics reports Cayenne’s AperFix System provides a safe, efficient and secure means of arthroscopic reconstruction of the PCL due to traumatic injury.
The AperFix System is a femoral and tibial fixation device originally designed for soft tissue ACL reconstruction. AperFix is proven to restore native knee kinematics through a simple, single-incision all-inside technique that allows the implant to be inserted transtibially, or anteromedially, through a single-tunnel eliminating the need to drill through the femoral cortex, Cayenne noted.
The study, titled Arthroscopic PCL Reconstruction with a Novel All-Inside Femoral Fixation Device: A Single-Incision Technique, is authored by John W. Uribe, MD; Luis Vargas, MD; and Brian M. Leo, MD.
“PCL reconstruction with the AperFix System is designed to alleviate the challenges some surgeons may experience with conventional BTB (bone-tendon-bone) allografts or soft tissue grafts utilizing cortical fixation techniques,” James W. Hart, president and CEO of Cayenne Medical, stated in the press release. “This study not only highlights the flexibility of the system as a solution for multiple ligament reconstructions, it also shows the novel procedure provides superior fixation and knee stability for patients and ease-of-use for surgeons due to aperture fixation.”
In the study, six active PCL injury patients successfully underwent PCL reconstruction surgery using the system. At 6 months, all patients achieved restored knee stability and full, symmetric range of motion, allowing them to return to their previous level of activity. Full recovery following PCL reconstruction surgery typically requires six to 12 months.
The study’s authors concluded that the single-incision all-inside femoral fixation technique efficiently performs arthroscopic soft tissue PCL reconstruction. They cited benefits compared to traditional methods, which include reduced bone and soft tissue injury, eliminated need for patient repositioning during surgery and a simplified passage of the allograft through the posterior aspect of the tibia.
