    Partial Knee Replacement is a treatment option for adults living with early to mid-stage osteoarthritis (OA) that has not progressed to all three compartments of the knee. MAKOplasty® Partial Knee Resurfacing is an advanced treatment option. It is powered by the RIO® Robotic Arm Interactive Orthopedic System, which allows the surgeon to perform surgery accurately through a smaller incision as compared to manual procedures. By selectively targeting the part of the knee damaged by OA, surgeons can resurface the knee while sparing the healthy bone and ligaments surrounding it.

    MAKOPLASTY® PARTIAL KNEE RESURFACING BENEFITS MAY INCLUDE:
    -Preservation of healthy tissue and bone—only diseased portions are removed
    -Optimal implant positioning
    -Less pain
    -A more natural feeling knee following surgery
    -More rapid recovery and shorter hospital stay compared to traditional total knee Resurfacing surgery

    Partial knee replacement is a treatment option for people with early to mid-stage osteoarthritis (OA) that has not yet impacted their entire knee. Only the diseased portion of the knee is replaced, sparing healthy bone and the ligaments known as the ACL (anterior cruciate ligament) and PCL (posterior cruciate ligament).

    MAKOplasty Partial Knee Resurfacing is an advanced partial knee surgery performed with the RIO® Robotic Arm Interactive Orthopedic System. It can be performed as a unicompartmental procedure to address OA in any of the three compartments of the knee: the medial (inner), patellofemoral (top), or lateral (outer) compartments. There is also a bicompartmental option for OA in both the medial and patellofemoral compartments.

    Partial knee replacement can be a challenging procedure to perform accurately on a consistent basis using manual techniques. Robotic arm assisted MAKOplasty enables consistent results and more accurate implant placement—which is an important factor in the life expectancy of implants. In an ongoing study, MAKOplasty resulted in both greater accuracy in implant placement and less pain in the first eight weeks post-surgery compared to manual partial knee replacement using Oxford® implants.1 Another study found that unicompartmental MAKOplasty patients who received RESTORIS® MCK Medial Onlay implants, showed a very low failure rate of only 0.4% at two years2, which is nine times lower than that of manual surgery. The study was conducted by four surgeons, who evaluated 201 patients (224 knees).2

    Before surgery, a CT scan is taken of the patient's knee, and a 3D model created using the RIO system's software. From this model, a pre-surgical plan is developed for the positioning of implants based on that patient's unique anatomy.

    To ensure implants are optimally positioned and that the soft tissues of the knee are balanced for a good surgical outcome, surgeons can test and fine tune the plan before surgery by moving the leg through different ranges of motion. The RIO provides measurements and visualization, and the surgeon adjusts the plan as needed.

    Once the surgical plan is finalized, it is programmed into the RIO, which creates a safety zone for bone removal. While the surgeon guides the robotic arm and is in control of it at all times, the RIO ensures that bone removal stays with the safety zone of the surgical plan, providing 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 implants are placed in the knee.
