Technique Guide VersiTomic® PCL Technique Michael A. Rauh, MD The opinions expressed are those of Dr. Rauh and are not necessarily those of Stryker VersiTomic PCL Technique Michael Rauh, M.D. is an Orthopaedic Sports Medicine specialist at the University at Buffalo. His surgical cases focus on the latest techniques in arthroscopic surgery of the knee, shoulder, and elbow, as well as, general orthopaedic reconstructive surgery, and trauma surgery. During his Sports Medicine Fellowship at the renowned Cleveland Clinic, Dr. Rauh worked with the Cleveland Browns, Indians, and Cavaliers. While in Buffalo, Dr. Rauh serves as the medical director and team physician for the Buffalo Bandits of the National Lacrosse League. Dr. Rauh is the Clinical Assistant Professor of Orthopaedic Surgery for the School of Medicine and Biomedical Sciences, University at Buffalo, where he teaches orthopaedic sports medicine fellows, residents, medical students, and conducts research. Michael Rauh, M.D Orthopaedic Sports Medicine specialist at the University at Buffalo and Clinical Assistant Professor of Orthopaedic Surgery, School of Medicine and Biomedical Sciences, University at Buffalo I ntroduction Surgeons should consider anatomy, scientific evidence and their own experience when deciding to perform this surgery as well as considering single versus double bundle PCL reconstructions. Arthroscopic Evaluation and Debridement 1. Care is taken to identify the anatomic insertion points of the PCL on both the femur and tibial surfaces. 2. The PCL remnant on the medial wall of the intercondylar notch is debrided arthroscopically. Note the respective PCL footprints, especially if choosing to perform double bundle reconstructions. 3. Creation of a posteromedial portal is usually helpful. This can be accomplished with spinal needle localization and visualization with a 70° arthroscope through the notch superior to the ACL. A posteromedial cannula is often useful to aid in later insertion and removal of instruments and arthroscope. Locate tibial PCL footprint and begin to remove the remaining PCL fibers using a combination of shaver, Stryker PCL Curette, and Stryker PCL Liberator/Rasp. Stryker PCL Liberator/Rasp has 3 functions: • Liberator with a tapered tip for elevating soft tissue • Rasp to assist in removal of tissue/bone • The pin hole located just above the rasp can serve as a pin protector while reaming the tibial tunnel Tibial S Guide Assembly a Unscrew the knob until it is in its final unlock position, press in the button and slide tibial arm into place. Adjust angle and tighten down the knob to the lock position. Squeeze sides of Backstopper and slide over distal aspect of tibial spine into slots. b Pre-chuck the 2.4mm guide pin up to the back of the Backstopper to provide a positive stop when drilling. This is done to assist in preventing over drilling of the tibial pin. c Ensure the pin meets the PCL capture cup. Figure 1b. Figure 1c. Tibial Tunnel Guide Placement 1. A 30° arthroscope is placed into the PM portal. 2. Insert the Stryker PCL Tibial Arm into the joint through the AM portal. Tips: • Central or AM portal helps to avoid condyles • Remove bullet entirely when inserting the guide • Hold upside-down as bringing it into incision, then flip around once inside joint The guide is designed to accommodate two PCL tibial tunnel insertion sites (based on surgeon preference and specific to each patient’s individual anatomy). • Posterior View A: within the native PCL footprint • Posterior View B: approximately 14 mm down the back of the tibia (when bottomed out against tibial plateau) Figure 2. Posterior View A Posterior View B Tibial Tunnel Use the pre-chucked 2.4 drill tip guide pin to drill tibial tunnel. Be sure to flip down the Backstopper and drill until the Jacob’s Chuck hits the Backstopper, which oocurs when the 2.4 guide pin tip should be inside the PCL capture cup. Fluro may be used to monitor/evaluate pin. Drilling should occur with visualization through the PM portal. Pin Protector The PCL Tibial Arm is designed to be a pin protector. Tips to prevent advancement of the guide pin through the PCL capture cup window: • Remove the Bullet and Backstopper • Drop your hand to capture the guide pin in the ‘cup’ of the guide, away from the ‘window’ • Alternatively, you can use the hole in the Liberator/Rasp as a pin protector. The position of the guide pin is verified using fluoroscopy. Drill tibial tunnel using appropriate sized Stryker VersiTomic Cannulated Drill. Completion of the tibial tunnel drilling may be done by hand reaming. S Figure 3. Femoral Tunnel – Outside-In For the outside-in technique, the PCL Femoral Arm is attached to the tibial spine and inserted into the joint. Laser lines on the femoral arm help to measure distance from the articular cartilage. Care is taken to ensure anatomic tunnel placement whether performing single or double bundle reconstructions. Make a small incision and advance the guide bolt through medial soft tissues and secure to bone. Drill the pin from outside – in and advance the reamer over the guide pin. Figure 4. Graft Passage and Fixation Use a grasper, 18 gauge wire, or surgical wire to pass a suture loop through the tibial tunnel. Use the suture manipulator or probe to pull the suture through joint space and out the anterolateral portal. Use the eyelet of the femoral pin to pass suture through femoral tunnel. Use passing suture to pass the graft through the tibial tunnel and femoral tunnels. Graft fixation techniques and implants are surgeon and patient specific based upon implant IFU, patient anatomy, and surgeon preference.
