The Technology Behind Robotic Knee Replacement

The Technology Behind Robotic Knee Replacement

Key Highlights

• 3D Registration & Mapping: The surgeon uses reflective tracking arrays to overlay a pre-operative CT scan directly onto the patient's actual bone anatomy, providing a precise "roadmap" for the robot.
• Pre-Planning & Sizing: Before making any incisions or cuts, the software allows surgeons to preview, rotate, and adjust the femoral and tibial implant sizing to ensure a tailored fit.
• Dynamic Joint Balancing: The robot measures ligament stability dynamically while flexing and extending the knee in real time, helping surgeons optimize joint balance and overall stability.
• Haptic Boundary Protection: During bone cuts, the robotic arm guides the saw blade and utilizes haptic boundaries, preventing the blade from extending past designated areas into surrounding soft tissue.
• Trial Verification: Prior to placing the final permanent implants, trial components are attached to re-verify range of motion, joint balance, and stability under stress.
