MAKOplasty® partial knee resurfacing is a minimally invasive procedure for those suffering with painful early to mid-stage osteoarthritis of the knee. It is performed using the surgeon-controlled RIO® robotic arm system and offers more accurate resurfacing of the diseased portion of the knee, saving as much of the original knee as possible.

St. John's is very proud to be the First and Only hospital in Westchester County to offer this technology! MAKOplasty® benefits the patient and the surgeon.  MAKOplasty® is a minimally invasive partial knee replacement procedure which uses a computerized navigation system. The system features RIO® Robotic Arm Interactive System: an interactive robotic arm and visualization technology that allows the surgeon to create a surgical plan. Using an initial CT scan, the technology creates a 3-dimensional virtual view of the bone surface. This virtual view guides the surgeon in how much bone to shave off, and the exact boundaries of that specific, damaged area. It also allows the surgeon to precisely align the implants. This technology will be used to help those who have osteoarthritis of the knee.
MAKOplasty may:

• Promote a more rapid relief from pain, shorter hospital stay and quicker return to daily activities when compared to traditional knee replacement surgery
• Result in a more “natural” feeling knee following surgery

Before surgery, surgeons use the RIO system to pre-operatively plan and map the area(s) of diseased bone to be removed.  During surgery, 3-dimensional visualization of the knee and the robotic arm provide the surgeon with visual, tactile and auditory feedback so that only the diseased portion of the knee is resurfaced, sparing healthy bone stock and tissue.  

Typically, MAKOplasty patients share the following characteristics:

• Knee pain with activity, usually on the inner knee, under the kneecap or the outer knee
• Start up knee pain or stiffness when activities are initiated from a sitting position
• Failure to respond to non-surgical treatments, injections or non-steroidal anti-inflammatory medication

In many cases, patients are permitted to walk soon after surgery, drive a car within two weeks and return to normal daily activities shortly thereafter.  Please speak with your surgeon to determine if MAKOplasty may be the right treatment option for you.
