Types of Joint Replacement


MAKOplasty is performed using RIO®, the Robotic Arm Interactive Orthopedic System. RIO provides three-dimensional modeling to help your surgeon plan your procedure, and it gives the surgeon real-time feedback during surgery to ensure accurate implant placement and alignment.  Memorial Hermann Memorial City is one of few hospitals in the area with this technology. 

Partial Knee

MAKOplasty partial knee replacement is the ideal solution for patients with arthritis in only one or two compartments of the knee.  Total knee replacements, once thought to be the only option, are no longer the only choice for many patients.  During this procedure, the diseased part of the knee is resurfaced, sparing the healthy bone and surrounding tissue.  The surgeon places the implant in the joint to allow the knee to move normally again.

Benefits include:

  • Smaller incisions
  • Shorter, or no, hospital stay
  • Healthy bone and tissue preserved
  • Faster recovery and return to normal activities
  • A more natural-feeling knee after surgery

Total Hip

MAKOplasty total hip replacement allows for increased precision and accuracy of surgical technique, thus decreasing the risk for post-operative complications, promoting implant longevity and improving the ability to restore appropriate leg length.

Benefits include:

  • Enhanced joint stability and mobility
  • Smaller incisions
  • Shorter hospital stay than traditional hip replacement surgery
  • Faster recovery and return to normal activities

Computer Assisted/Navigation

Computer-assisted surgery, also known as Navigation, utilizes advanced technology that provides valuable information about the joint and the patient’s anatomy to the surgeon. The surgeon is able to pre-plan the surgery using CT images and Navigation software to determine the most accurate implant placement.  The results are improved alignment and orientation of the implant and greater range of motion, stability and mobility, thus causing less wear and tear on the implant.

Custom Fit Implants

Custom Fit implants are patient-specific implants that are made to fit the unique shape of your knee.  These implants are made possible due to advanced CT and MRI technology.  This technology converts CT/MRI data into implants that are designed to conform to the unique 3D structure of your joint.

The design process begins when you receive a diagnostic scan as prescribed by your surgeon. We then map the surface contours of your joint in the areas affected by osteoarthritis. This information facilitates the creation of an implant that is designed to precisely match your individual knee anatomy.

Benefits include:

  • Implant matched to individual size and shape
  • Natural, anatomic feel and alignment
  • Significant bone preservation
  • Less trauma to the knee during surgery
  • Faster recovery time
