MAKOplasty® Partial Knee Resurfacing is an innovative treatment option for adults living with early to mid-stage osteoarthritis that has not progressed to all three compartments of the knee. It is powered by the RIO® Robotic Arm Interactive Orthopedic System, which allows for consistently reproducible precision in performing partial knee resurfacing.

During the procedure, the diseased portion of the knee is resurfaced, sparing the patient’s healthy bone and surrounding tissue. An implant is then secured in the joint to allow the knee to move smoothly again. MAKOplasty® can:

  • Facilitate ideal implant positioning to result in a more natural feeling knee following surgery
  • Result in a more rapid recovery and shorter hospital stay than traditional knee replacement surgery
  • Be performed on an outpatient basis
  • Promote a rapid relief from pain and return to daily activities

As a knee arthroplasty procedure, MAKOplasty® is typically covered by most Medicare-approved and private health insurers.

How does MAKOplasty® work?

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

What are the benefits of MAKOplasty®?

In addition to relieving pain caused by joint degeneration, MAKOplasty® offers the following benefits:

  • Improved surgical outcomes
  • Less implant wear and loosening
  • Joint resurfacing
  • Bone sparing joint resurfacing
  • Smaller incision
  • Less scarring
  • Reduced blood loss
  • Minimal hospitalization
  • Rapid recovery

If I undergo MAKOplasty®, what can I expect?

MAKOplasty® can be performed as an inpatient procedure or on an outpatient basis. The orthopedic surgeon determines what is right for each patient. Where hospital stays are necessary, they average anywhere between one and three days; ambulatory patients return home the same day.

Many patients are permitted to walk soon after surgery, drive a car in just a few weeks, and resume a normal, daily routine shortly thereafter.

What is the lifespan of a MAKOplasty® implant?

The life expectancy of implants depends on several factors including:

  • Patient’s weight
  • Activity level
  • Quality of bone stock
  • Compliance with physician’s orders

Proper implant alignment and precise positioning during surgery are also very important factors that can improve the life expectancy of an implant. The use of RIO® aligns implants to ensure maximum lifespan.

RESTORIS® MCK implants enable the treatment of one or two compartments with OA. With single compartment disease, a second compartment may be treated in the future if OA spreads. In addition, because very little bone is actually removed during a MAKOplasty® procedure, the implants can be replaced with another procedure such as a total knee replacement, if necessary.

Individual results may vary. There are risks associated with any knee surgical procedure, including MAKOplasty.® The physician can explain these risks and help determine if MAKOplasty® is right for the patient.
