Are You Looking for a Custom Hip Replacement?

Are You Looking For A Custom Hip Replacement?

by Trevor H. Magee, MD

We are pleased to announce the availability of the recently released upgraded software for the Robotic Assisted Total Hip Arthroplasty.  MAKOplasty total hip replacement application is designed to support the surgeon’s ability to more accurately align and position the implants relative to the patient’s specific anatomy.  Thjs is designed to allow the surgeon to reduce potential complications associated with conventional total hip replacement surgery.

A recently published Massachusetts General Hospital study reported on a series of 1,823 total hip replacements. Of those studied nearly 50 percent of the acetabular cups (cup-shaped sockets of the hip joint) were malpositioned.  Thus, greater than 50 percent of the cups that were place with conventional techniques were not placed in an acceptable position despite being placed by experienced surgeons. Malpositioning of acetabular cups in total hip replacement surgery may lead to impingement that can cause dislocation, fracture, and increased implant wear.  This study was repeated utilizing MAKO robotic assisted surgery and less than 1% were place outside the acceptable range.

What does this mean to patients needing hip replacements? Before surgery, the RIO® system’s software creates a 3-D model of your hip based on a CT scan. Implant positioning is planned by the surgeon for your unique anatomy pre-surgically.  During surgery, RIO® provides real-time data to the surgeon to optimize implant positioning and alignment.  The robotic arm is used by the surgeon to prepare the acetabular socket for implantation.  A summary of your results are viewed at the end of the procedure.  We know from studies that properly positioned hip implants increase the longevity, increase stability, and decrease dislocation risks of the total hip replacement.
