MAKO Hip and Partial Knee Replacement Surgery

MAKO Robotic-Arm Assisted Technology: a new alternative to treating osteoarthritis of the hip or knee

If you suffer from hip or knee pain and need a total hip or partial knee replacement, there’s a new option. Reston Hospital Center is proud to offer our patients an alternative to treating hip or knee osteoarthritis. The MAKO Robotic Arm-Assisted Technology is an advanced technology that assists surgeons in restoring your mobility and active lifestyle. And, in Northern Virginia, you can get it at Reston Hospital Center.

MAKOplasty® is powered by the surgeon-controlled MAKO Robotic Arm-Assisted Technology, which enables advanced treatment options for more accurate hip and knee implant placement. The robotic arm technology allows surgeons to more accurately achieve the biomechanical alignments that are planned to fit the patient’s unique anatomy.

The MAKO technology provides a surgeon-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, MAKO technology 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 MAKO Robotic-Arm Assisted Technology. 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 MAKO provides summary data to confirm the hip implants are aligned according to plan.

Total Hip Replacement with MAKO 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, Total Hip Replacement with MAKO 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

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.

MAKO Partial Knee Replacement 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 MAKO Robotic- Arm Assisted Technology 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 MAKO Partial Knee procedures may still be a candidate for a total knee replacement procedure later in life if necessary.

The MAKO Partial Knee Replacement 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.

If your surgeon determines that you are a good candidate for the MAKO Robotic-Arm Assisted Surgery, he or she will schedule a computed tomography (CT) scan of your hip or knee one or two weeks prior to your surgery date. This is used to create your unique surgical plan for optimal implant replacement.

Your physician should discuss the specific risks associated with MAKO and other treatment options with you. In addition, you should be informed of any pre-operative and post-operative instructions by your surgeon or his or her staff.

As a knee arthroplasty procedure, MAKO Robotic-Arm Assisted Surgery is typically covered by Medicare insurers — check with your private health insurers. In some cases it may be performed on an outpatient basis depending on what your surgeon determines is the right course of treatment for you.
