What Happens During Surgery?

During total hip replacement (also called total hip arthroplasty), a surgeon removes the arthritic ball end of the femur (top of thigh bone) and inserts a metal component (a stem) into the bone. The surgeon also replaces the hip socket with an acetabular cup lined with durable polyethylene plastic.

In clinical studies, total hip replacements using Mako SmartRobotics™ have resulted in more accurate placement and alignment of hip implants, less likelihood of dislocation, reduced blood loss, more preservation of healthy bone, and better replication of the feeling of a natural hip.
