Why MAKOplasty® Robotic Arm Total Hip Replacement?

Uses highly advanced, surgeon-controlled robotic arm technology and a high-definition, patient-specific visualization system to pre-plan and treat each patient uniquely with consistently reproducible precision.

Potential Benefits

  • Accurate placement and alignment of hip implants for the patient’s unique anatomy
  • More consistency in leg length and hip offset
  • Reduced risk of impingement and dislocation—may improve life expectancy of an implant

Before Surgery

  • A CT scan of your hip is taken prior to surgery
  • The RIO® software is used to create a 3-D model of your unique anatomy
  • Allows surgeon to plan placement and alignment of hip implants before surgery

During Surgery

RIO® provides visualization and measurements during the surgery, enabling the surgeon to adjust the surgical plan as needed to optimize implant positioning and alignment.

The thighbone (femoral bone) is prepared first. Measurements are taken of the stem’s planned position.

Robotic Arm Assisted Cup Placement

Next, the surgeon uses the robotic arm to

  • Prepare and shape the socket (acetabulum) in the pelvis
  • Accurately place the cup implant in the hip’s center of rotation in terms of depth and orientation
    – Restoring center of rotation of the hip correctly allows hip muscles and biomechanics to function more naturally

Final Steps and Surgical Results

Once the acetabular cup is implanted, a plastic liner is locked into the cup. Then the femoral stem is implanted and the correct-sized femoral head is attached to obtain a stable joint and reproduce an appropriate leg length.

The RIO® system helps assure the position and orientation of the stem and cup are optimized for proper joint reconstruction and mobility.
