Robotic Assisted Joint Replacement
If you suffer from hip or knee pain and are looking into joint replacement, there’s a new option available at St. Mark’s hospital. The Mako technology assists surgeons in treating osteoarthritis of the hip or knee and restoring your mobility and active lifestyle.
The robotic-arm assisted technology that provides you with a personalized surgical plan based on your unique anatomy. A 3D model of your hip or knee will be used to pre-plan and assist your surgeon in performing total hip replacement, partial knee replacement or a total knee replacement.
Total Hip Replacement
The 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
- Rheumatoid 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
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.
Total Knee Replacement
MAKO Robotic-Arm Assisted Total Knee replacement is a treatment option for adults living with mid to late-stage osteoarthritis (OA) of the knee. MAKO provides you with a personalized surgical plan based on your unique anatomy. First, a CT scan of the diseased knee joint is taken. This CT scan is uploaded into the MAKO System software, where a 3D model of your knee is created. This 3D model is used to pre-plan and assist your surgeon in performing your total knee replacement.
During the procedure, the surgeon guides the robotic-arm to remove diseased bone and cartilage within the pre-defined area and the MAKO System helps the surgeon stay within the planned boundaries that were defined when the personalized pre-operative plan was created.
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).
