MAKO partial knee resurfacing is an advanced partial knee replacement surgery performed with the RIO Robotic Arm Interactive Orthopedic System. There are two options for performing MAKO depending on where the osteoarthritis is located in the knee.
- Unicompartmental: any one of the three compartments of the knee, the inner, top, or outer compartments, can be replaced
- Bicompartmental: only two compartments, specifically the inner and top compartments, can be replaced
Prior to surgery, the following steps are taken:
- CT scan of the knee is taken
- 3D model is created using the RIO system’s software
- Pre-surgical plan is developed for positioning the knee implants based on the patient’s anatomy
- The plan is tested and fine-tuned by the orthopedic surgeon who moves the leg through different ranges of motion to ensure the implants will be optimally positioned and the soft tissues of the knee are balanced for a good surgical outcome. The RIO system provides measurements and visualization.
- The final surgical plan is programmed into the RIO system
During surgery, the orthopedic surgeon guides the robotic arm and is in control of it at all times. The RIO system ensures that bone removal stays with the safety zone of the surgical plan. The system provides auditory, visual and tactile feedback, stopping the robotic arm if necessary before bone can be removed outside the planned area. Once the bone preparation is complete, the orthopedic surgeon places the implants in the knee.
