The instrumentation also includes lateral-specific tools such as MCL retractors, along with preparation, alignment, balancing, and trialing instruments designed to support each stage of the procedure. View Instructions for Use The Lateral Technique The lateral technique follows a structured surgical sequence designed around access from the outside of the knee while preserving the quadriceps. From incision and exposure through bone preparation, trialing, balancing, and final implantation, each stage works together to support precise component placement and a consistent total knee replacement workflow. Lateral Incision Access begins along the lateral side of the knee. Quadriceps Preserved The quadriceps are lifted rather than cut. Patella Managed for Access The patella is carefully managed to provide the exposure needed for the procedure. Bone Prepared Femoral and tibial surfaces are prepared for the implants. Components Trialed Trial components help evaluate fit, alignment, and balance. Implants Placed Final components are positioned to reconstruct the knee joint.

All ResourcesSurgical GuidesInstructions for Use What Is The Lateral Approach? A Muscle-Sparing Way to Access the Knee The lateral approach changes how surgeons access the knee during total knee replacement. Instead of using a traditional midline pathway, the surgeon enters from the outside of the knee. This muscle-sparing technique avoids cutting the quadriceps and helps preserve more surrounding tissue. By reducing disruption to the front of the knee, the technique is designed to support earlier mobility, less pain and numbness, faster recovery, and a more discreet incision location for patients. Explore the Lateral Approach See How It Works Preserves the Quadriceps Avoids cutting through the quadriceps muscle during the surgical approach. Lateral Incision Placement Moves the incision away from the traditional front-of-knee surgical pathway. Supports Faster Recovery Muscle-sparing access is designed to support earlier mobility, strength, and recovery. Lateral-First Engineering Specialized implants and instrumentation are designed specifically for lateral access.

These stories share the progress, milestones, and everyday wins that made the biggest difference along the way. Patient StoriesSurgeon Stories Sharon At six days, my knee bent to 120. I used a walker for possibly a day, and by the end of the first week, I was walking a mile. Debra It’s opened up my life again to do the things that I love to do. Marta If you’re miserable with your knees and walking, and it changes your life so you can’t do the things you want to do, I say go get it done.
