It emphasizes restoring neutral mechanical axis alignment, achieving femoral and tibial component orientation, and ensuring secure fixation through accurate bone cuts and appropriate soft tissue balancing. The document details preoperative planning for anatomic-to-mechanical axis angles, sequential femoral and tibial preparation steps, trial reduction, component implantation, and optional techniques for gap management and finishing the femur and patella.","NexGen® Intramedullary Instrumentation  \nSurgical Technique  \nTable of Contents  \nIntroduction .............................................................................................................. 2  \nPreoperative Planning ......................................................................................... 2  \nSurgical Technique ................................................................................................... 3  \nStep One: Size the Femur/Establish External Rotation ......................................... 3  \nStep Two: Establish Femoral Alignment ............................................................... 4  \nOptional Technique  \nStep Three: Cut the Anterior Femoral Condyles ................................................... 5  \nStep Four: Cut the Distal Femur ........................................................................... 5  \nRemoving Additional Bone  \nOptional Technique  \nSurgical Option  \nStep Five: Finish the Femur .................................................................................. 8  \nOptional Technique  \nStep Six: Cut the Proximal Tibia.......................................................................... 10  \nUsing the TM Tibial Resector  \nUsing the Extramedullary Tibial Cutting Guide  \nOptional Technique  \nStep Seven: Prepare the Patella ......................................................................... 16  \nPatella Reamer Technique  \nUniversal Saw Guide Technique  \nFinish the Patella  \nStep Eight: Perform a Trial Reduction ................................................................. 22  \nUniversal Saw Guide Technique  \nSurgical Option  \nStep Nine: Finish the Tibia ................................................................................. 24  \nTibial Plate Preparation For Pegged Tibial Component  \nTibial Plate Preparation For Stemmed Tibial Component  \nComponent Implantation .................................................................................. 26  \nBearing Insertion ............................................................................................... 26  \nAppendix................................................................................................................. 27  \nOptional Techniques.......................................................................................... 27  \nCheck Flexion/Extension Gaps  \nRecutting the Distal Femur  \n“Crossover” Technique Option .......................................................................... 29  \nCrossover Technique with the 5-in-1 Femoral Finishing Guide  \nCrossover Technique with the PS Notch Milling Guide  \nCrossover Technique with the EPI Notch/Chamfer Guide  \nCrossover Technique with the Notch Chamfer Guide  \n2 | NexGen® Intramedullary Instrumentation Surgical Technique  \nIntroduction  \nSuccessful total knee arthroplasty is directly dependent on reestablishment of normal lower extremity alignment, proper component design and orientation, secure component fixation, and adequate soft tissue stability. The Intramedullary Knee Instrument System was designed to easily accomplish these goals, combining optimal alignment accuracy with a simple, straightforward technique.  \nThe center of the hip, knee, and ankle are restored to lie on a straight line, establishing a neutral mechanical axis. The femoral and tibial components are oriented perpendicular to this axis. Well-designed instruments allow accurate cuts to help ensure secure component fixation. Ample component sizes allow soft tissue balancing with appropriate soft tissue release.  \nIn addition, implant flexibility offers the opportunity to switch from a cruciate retaining prosthesis to a posterior stabilized prosthesis quickly and easily.  \nPreoperative Planning  \nUse the template overlay (available through your Zimmer Biomet representative) to determine the angle between the anatomic axis and the mechanical axis. This angle will be reproduced intraoperatively.
