Q: What is the MAKO Robot?
A: The MAKO robot is a robotic-arm that is used as a surgical tool during joint replacements. Depending on the surgery, the robot can either help make boney cuts on the knee or ream away bone in the hip.
​
Q: How does the MAKO Robotic Arm know what to cut?
The MAKO robot is entirely controlled by the surgeon and will not do anything without the surgeon's direction. A CT scan is first performed of the patient’s extremity prior to surgery. This CT scan provides the surgeon a 3-D view of the joint so the implant can be personalized to each patient. This can all be done before stepping foot in the operating room!

Q: What are the benefits of using MAKO Robot?
Studies have shown that the use of MAKO robotic-arm is associated with reduced postoperative pain, decreased opioid requirements, less blood loss, and better range of motion at discharge from the hospital. These improvements continued to be evident at 6 months postoperatively [1,2]
​
When pressure sensor technology is combined with the MAKO robot, 3 year patient satisfaction results approach 98% satisfaction! [3]

The MAKO Robot has unparalled accuracy allowing bone to be removed in <1 millimeter increments. This is much more accurate than human hands! This allows the implant to be placed exactly where the surgeon dictates to best match each patient's unique anatomy.

The MAKO Robot has "haptic boundaries" meaning that the if saw tries to move to an area that is not in line with surgical plan, the saw will shut down.
​
This ensures that the surgical plan is followed precisely and minimizes soft tissue damage and blood loss.
