Robotic Assisted Total Knee Replacement


This is a 68 year old female who presented with severe tricompartmental knee arthritis, a 10 degree fixed varus deformity, and a 15 degree flexion contracture. On X-ray she had severe osteophytes under the patellofemoral joint as well as the posterior femur. She underwent robotic assisted total knee replacement using Mako robotic technology.

Using a CT scan, a preoperative plan was created to provide optimal implant positioning, sizing, and ligamentous balance. The robotic arm adds precision to bone preparation during surgery by establishing haptic boundaries and soft tissue protection. In this challenging case, robotic technology was particularly helpful in deformity correction and ligamentous balance.
