TKA with Stryker MAKO Robot

Description

In this video, orthopedic surgeon Seth Jerabek introduces a robotic total knee replacement procedure at the Hospital for Special Surgery using the MAKO robotic system. The surgery targets bone-on-bone arthritis and patellofemoral issues. Seth discusses the significance of 3D planning to assess and visualize alignment parameters in various planes (coronal, transverse, sagittal) before commencing the surgery. He emphasizes creating concentricity on the medial femoral condyle and adjusting for external rotation to match the native trochlea.



Throughout the preparation phase, he plans for a slight varus alignment based on the patient's anatomical variations and existing measurements. He explains the methodology for assessing ligament tensions using specialized tools, ensuring a balance between the medial and lateral sides of the knee.



The benefits of the MAKO system are highlighted, particularly in making precise adjustments based on intraoperative findings and the haptic guidance that helps maintain alignment during bone cuts. Seth carefully balances the extension and flexion gaps, aiming for ideal laxity to ensure optimal functionality post-surgery.



As he continues with the operation, he emphasizes the importance of constant reassessment and adjustments to maintain proper knee alignment, which is crucial for the successful outcome of the procedure. He methodically checks gap measurements and prepares for the implant placement, demonstrating a thorough process that accounts for the intricate anatomy of the knee joint.
