Hip Replacement

MAKOplasty total hip arthroplasty is an innovative surgical treatment option for adults living with non-inflammatory or inflammatory degenerative joint disease. First offered in the Central Virginia region by HCA Virginia’s Chippenham Hospital, it is powered by the RIO Robotic Arm Interactive System, which allows our surgeons to achieve a new level of accuracy and precision.

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 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.

A hip implant consists of a cup and liner placed in the acetabulum, or socket, of the pelvis and 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.

MAKOplasty total hip replacement is designed to assist surgeons in attaining a new level of reproducible precision in surgery, to restore your confidence in your mobility and help you return to your active lifestyle.

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 such as

  • Osteoarthritis (OA), also called “wear and tear” arthritis, in which cartilage wears down over time
  • Post-traumatic arthritis, which results from a severe fracture or dislocation of the hip
  • Reheumatroid arthritis (RA), an inflammatory arthritis of the joints
  • Avascular necrosis (AVN), a condition where the “ball” or femoral head has lost its healthy supply of blood flow causing the bone to die and the femoral head to be misshapen
  • Hip dysplasia, a condition where bones around the hip did not form properly, which may cause misalignment of the hip joint

Partial Knee Replacement

MAKOplasty is a robotic arm assisted partial knee resurfacing procedure designed to relieve the pain caused by joint degeneration due to osteoarthritis (OA). By selectively targeting the part of your knee damaged by OA, your surgeon can resurface your knee while sparing the healthy bone and ligaments surrounding it.

MAKOplasty Partial Knee Resurfacing Can:

  • Enable surgeons to precisely resurface only the arthritic portion of the knee
  • Preserve healthy tissue and bone
  • Facilitate optimal implant positioning to result in a more natural feeling knee following surgery
  • Result in a more rapid recovery and shorter hospital stay than traditional total knee replacement surgery

Unlike other more invasive procedures, MAKOplasty can often be performed through a four to six inch incision over your knee with small incisions in both your femur (thigh bone) and tibia (shin). Additionally the preservation of your own natural bone and tissue along with more ideal patient specific implant positioning may also result in a more natural feeling knee. And since healthy bone is preserved, patients who undergo MAKOplasty partial knee procedures may still be a candidate for a total knee replacement procedure later in life if necessary.

The MAKOplasty procedure is indicated for patients suffering from unicompartmental or bicompartmental knee disease. A total replacement is sometimes necessary if your surgeon discovers during surgery that your knee has more damage than originally seen in the pre-operative X-rays and CT scan.
