Designed by Surgeons, for Surgeons Cementless Cruciate Retaining (CR) Knee System Engineered for cementless fixation with porous implant surfaces and cruciate-retaining options within the OI Blue platform. Request Demo KitSurgical Technique Guide Porous Fixation Technology Advanced Porous Surfaces for Biological Fixation The cementless system incorporates porous bone-contacting surfaces designed to maximize interface coverage and support biological fixation. The femoral component features a porous sintered cobalt chrome coating, while the tibial tray uses additively manufactured porous titanium with an irregular, interconnected three-dimensional pore structure. Together, these components provide porous fixation options across the femur, tibia, and patella. Porous Cobalt Chrome Femoral Component Additively Manufactured Porous Titanium Tibial Tray Cementless Metal-Backed Patellar Option Articular Surface Design Designed for Stability Through Flexion The OI Blue system offers modular tibial insert options designed to provide stability throughout the arc of flexion while giving surgeons flexibility in component selection. Cruciate-retaining and highly congruent CR inserts work within the same broader implant platform, allowing surgeons to select the appropriate articulation based on surgical requirements. The inserts are manufactured from Vitamin E-enhanced highly cross-linked polyethylene and are compatible with both cemented and cementless OI Blue femoral components. Indications The Optimotion Blue Total Knee System is indicated for painful, disabling joint disease of the knee resulting from conditions including osteoarthritis, traumatic or post-traumatic arthritis, avascular necrosis, and rheumatoid arthritis. Additional indications include certain knee deformities, revision procedures, and fractures of the distal femur and/or proximal tibia that cannot be stabilized using standard fracture-management techniques.

View Product 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. Outpatient Advantages How OI Systems Support ASC Efficiency Efficient Procedures A streamlined surgical workflow can help support efficient use of valuable OR time. Streamlined Instrumentation Four dedicated trays organize preparation and trialing across the total knee procedure. Lower Sterilization Burden A focused instrumentation setup can help reduce reprocessing demands between surgical cases. Faster Room Turnover A more streamlined workflow and instrument setup can help support efficient case turnover. 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. Kneecap Mobilized The kneecap is moved to provide surgical access. 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.

Become an OI Surgeon Hear From Surgeons Using the Lateral Approach These physicians share what they’ve learned using the lateral approach, what has stood out in their patients’ recoveries, and why the technique has become part of their practice. Surgeon TestimonialsPatient Testimonials Dr. Pasquale Reino Over 95% of my patients who had a traditional surgery and then came to me for the lateral approach say the recovery was much faster in terms of motion, easier in terms of pain, and required less narcotic medication. Dr. David Cheong The quadriceps muscle is not cut. If a muscle isn’t cut, then it doesn’t take the same amount of time to recover and wake up. If a muscle isn’t cut, then typically there is less pain associated with that surgery. Dr. Sergio Martinez I’ve had patients where we did the standard approach on one knee, and we did the second knee with the lateral approach. They all tell me that the lateral approach was a much better recovery.
