Mako™ Robotic-Arm Assisted Surgery Enables a New Level of Accuracy and Reproducibility for Partial Knee and Total Hip Replacement

Ocala, FL – Ocala Health is the first in greater Marion County to offer Mako Partial Knee Replacement and Mako Total Hip Replacement procedures, performed using the Mako Robotic-Arm Assisted Surgery System marketed by Stryker. The Mako system is a surgeon-controlled robotic arm system that enables accurate alignment and placement of implants. The robot will be used at Ocala Regional Medical Center by orthopedic surgeons on the medical staff of Ocala Health.

Accuracy is key in planning and performing both partial knee and total hip procedures. The Mako system enables surgeons to personalize partial knee and total hip arthroplasties to achieve optimal results at a level of accuracy and reproducibility previously unattainable with conventional instrumentation.

The Mako System features a patient-specific visualization system and proprietary tactile robotic arm technology that is integrated with intelligent surgical instruments. It assists surgeons in pre-planning and in treating each patient uniquely and with consistently reproducible procedure.

Mako Partial Knee Replacement is a treatment option for adults living with early to mid-stage osteoarthritis that has not yet progressed to all three compartments of the knee. It is less invasive than traditional total knee surgery. A pre-surgical plan is created based on a CT scan of the patient’s own knee, and the surgeon uses the robotic arm during surgery to resurface the diseased portion of the knee, sparing healthy bone and surrounding tissue for a more natural feeling knee. An implant is then secured in the joint to allow the knee to move smoothly again.

During Mako Total Hip Replacement surgery, the Mako system provides visualization of the joint and biomechanical data to guide the bone preparation and implant positioning to match the pre-surgical plan. After first preparing the femur or thighbone, the surgeon uses the robotic arm to accurately ream and shape the acetabulum socket in the hip, and then implant the cup at the correct depth and orientation. The surgeon then implants the femoral implant. The Mako procedure offers the confidence of more accurate cup placement and accurate leg length restoration.
