Special Procedure

Special procedure: All Epiphyseal ACL

By Dr. Lucas Murnaghan

With the increased participation of growing athletes in organized sport, pediatric ACL injuries are becoming more common. Recent literature has demonstrated that early and reliable stabilization of the rotational and translational instability of the knee is crucial for the preservation of meniscal and articular cartilage integrity. The surgical management of ACL injuries in the growing athlete requires special consideration. Traditional ACL reconstructions cross the open growth plates about the knee: distal femur and proximal tibia. Growth disturbance following such reconstructions has been reported and presents a concern due to the percentage of overall growth of the lower extremity that these growth plates contribute. In response to this, Allen Anderson from Nashville, TN described an all-epiphyseal ACL reconstruction. His technique allows for an anatomic reconstruction that spares thephysis. My preferred technique is a modification of his original description and keeps not only the femoral and tibial tunnels within the physis, but also the fixation of the graft. My indication for this procedure is a patient with greater than three years of growth remaining.

Technical Steps

Using this technique, my standard ACL set-up provides all of the equipment necessary. I use mini C-arm fluoroscopy for visualization of the epiphysis and ensuring that my tunnels are accurately placed. I begin with harvesting the tendons of gracilis and semitendinosus and prepare the graft on the back table to form a quadrupled hamstring graft. Knee arthroscopy follows with management of meniscal or cartilage pathology. I use fluoroscopy to achieve a perfect lateral of the distal femur in order to place the guide wire for the femoral tunnel. The position is confirmed arthroscopically and over-reamed to the size of the graft. Similarly, the tibial tunnel is drilled using fluoroscopic guidance.


I use a knee immobilizer for 2 weeks post operatively for comfort and begin early work on regaining full extension. I use a closely supervised goal-based physiotherapy protocol post-operatively with return to sport at 6 months once return to sport criteria have been met. I follow my patients with annual clinical examinations and radiographs until skeletal maturity.


Once the tunnels are prepared, the graft is passed from proximal to distal and the Endobutton Direct is flipped on the anterior cortex of the tibia. The graft is tensioned in 20 degrees of flexion and the femoral side fixated with an interference screw. Stability and knee range are confirmed and surgical sites closed.

legend names
“It is hard to express what the SickKids experience has meant to me. I have been stretched in so many different ways. If I had to pick out one thing it would be the approach to tackling difficult problems. There is no way to see everything in a fellowship that one will encounter throughout an individual’s lifetime. However, SickKids has provided me with a principle-based approach to clinical problem solving that I greatly appreciate. It is one of the many benefits of training at a program with such a wide array of staff and fellows with different educational backgrounds. This is a special place.”
