HCA Virginia Now Offering MAKOplasty® Hip Replacement Robotic Arm Technology Enables a New Level of Precision in Total Hip Replacement

April 28, 2014

Richmond, Va. (April 22, 2014) — HCA Virginia's Chippenham Hospital is the first in the region to offer MAKOplasty® Hip, the latest innovation in total hip replacement surgery performed using the RIO® system - a highly advanced, surgeon-controlled robotic arm system that enables the accurate alignment and positioning of implants.

David Miller, M.D., an orthopedic surgeon with Chippenham Hospital and OrthoVirginia, first performed the MAKOplasty® total hip procedure last week.

"Getting implants positioned correctly is an important aspect in improving surgical outcomes and the lifespan of the implants used for hip replacement," said Miller. "The robotic arm technology enables us to more accurately achieve the biomechanical alignments that are planned to fit the patient's unique anatomy."

Miller also says that accurate alignment and positioning of implants using traditional manual total hip replacement techniques can be challenging.

During a MAKOplasty Hip replacement, the RIO system provides a patient-specific 3-D image of the patient's hip based on a pre-operative CT scan. Using the 3-D model, the surgeon can then plan the optimal size and position of hip implant components.

An implant consists of a cup and liner placed in the acetabulum or the socket of the pelvis, and a femoral component with a femoral head and stem. The femur is the bone that extends from the hip socket to the knee. The position of these components is critical for proper biomechanical reconstruction of the hip.

During surgery, RIO provides visualization of the joint and biomechanical data to guide the bone preparation and implant positioning to match the pre-surgical plan. First the surgeon prepares the femoral bone for the implant, and subsequently measures the femoral component's position with the RIO.

Next the surgeon uses the robotic arm to accurately ream and shape the acetabulum, and then implant the cup at the correct depth and orientation. Finally the surgeon implants the femoral implant and RIO provides summary data to confirm the hip implants are aligned according to plan.

MAKOplasty Hip is designed to assist surgeons in attaining a new level of reproducible precision in surgery, to restore patients' confidence in their mobility and help them return to active lifestyles.

Like other total hip replacement procedures, MAKOplasty Hip may be a treatment option for people who suffer from either non-inflammatory or inflammatory degenerative joint disease.
