MAKOplasty® Enables a New Level of Accuracy for Partial Knee and Total Hip Replacement
Hartford Hospital is first in the Greater Hartford Area to offer patients a new tool in orthopedic surgery. MAKOplasty® for partial knee resurfacing and total hip replacement procedures uses the RIO® Robotic Arm Interactive Orthopedic System. RIO is a surgeon-controlled robotic arm system that enables even more precise alignment and placement of implants.
RIO enables surgeons to personalize partial knee and total hip arthroplasties to achieve optimal results with a level of accuracy previously unattainable with conventional instrumentation. The RIO System features a patient-specific visualization system and robotic arm technology that is integrated with surgical instruments. It assists surgeons in pre-planning and treating each patient uniquely.

MAKOplasty Partial Knee Resurfacing 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 knee. 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 MAKOplasty Total Hip Replacement surgery, RIO 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 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. MAKOplasty offers the confidence of more accurate cup placement and accurate leg length restoration.
Like other total hip replacement procedures, MAKOplasty may be a treatment option for people who suffer from either non-inflammatory or inflammatory degenerative joint disease.
Robotic Arm Interactive Orthopedic System (RIO®)
The RIO® Robotic Arm Interactive Orthopedic System features three dimensional pre-surgical planning. During surgery, the RIO® provides the surgeon with real-time visual, tactile and auditory feedback to facilitate optimal joint resurfacing and implant positioning. It is this optimal placement that can result in more natural knee motion following surgery.
RIO® assists the surgeon in achieving natural knee kinematics and optimal results at a level of precision previously unattainable with conventional instrumentation.
- Accurately plan implant size, orientation and alignment utilizing CT-derived 3-D modeling
- Enabling the pre-resection capture of patient-specific kinematic tracking through full flexion and extension
- Real-time intra-operative adjustments for correct knee kinematics and soft-tissue balance
- Minimally invasive and bone sparing, with minimal tissue trauma for faster recovery

O-Arm® Surgical Imaging System
The O-arm® Surgical Imaging System, now in use at Hartford Hospital, is a multi-dimensional surgical imaging platform that is optimized for use in spine, orthopaedic, and trauma-related surgeries. It provides real-time, intra-operative imaging of a patient's anatomy with high quality images and a large field-of-view in both two and three dimensions.
By integrating O-arm surgical imaging technology with Medtronic's StealthStation® surgical navigation systems, surgeons are able to perform less invasive procedures and confirm the precision of advanced surgical procedures before the patient leaves the OR.

The O-arm® Surgical Imaging with StealthStation® Navigation provides:
- Speed in the OR: fast access to real-time, multi-plane 3D images (and 2D images)
- Ease in the OR: full support of the unique workflow of spinal procedures
- Safety in the OR: minimized radiation dose for surgical staff
- Confidence in the OR: visualization to confirm hardware therapy placement, potentially eliminating revision surgeries
