MAKOplasty Robotic Arm Partial Knee Resurfacing

MAKOplasty® Partial Knee Resurfacing is an advanced minimally invasive treatment option for adults suffering from osteoarthritis (OA) in one or two compartments of their knee. It is the only truly patient-specific procedure, planned and performed from a 3-D model of your knee. MAKOplasty is powered by the proven, highly accurate RIO® Robotic Arm Interactive Orthopaedic System, which allows surgeons to achieve consistently reproducible results so you can return to an active lifestyle.

MAKOplasty is designed to relieve the pain caused by joint degeneration due to osteoarthritis (OA). By selectively targeting only the diseased part of your knee, your surgeon can spare healthy bone, tissue, and ligaments. Other benefits may include a smaller incision, shorter hospital stay, less pain, reduced blood loss, less scarring, and a more rapid recovery.

MAKOplasty is indicated for patients suffering from osteoarthritis in one or two compartments of their knee. A total knee replacement is sometimes necessary if your surgeon discovers during surgery that your knee has more damage than originally seen in the pre-operative X-rays and CT scan.

MAKOplasty – A Less Invasive Procedure

MAKOplasty is enabled by robotic arm technology that allows the surgeon to perform the procedure accurately through a smaller incision when compared to standard manual procedures. Surgeons use the RIO® Robotic Arm Interactive Orthopaedic System, a surgeon-controlled robotic arm system that combines computer imaging with intelligent instrumentation. This allows the surgeon to more accurately place the implant that has been selected for your knee.

By preserving healthy bone, tissue, and ligaments, along with more accurate implant positioning, you can expect a more natural feeling knee. Since healthy bone is preserved, patients who undergo MAKOplasty partial knee procedures may still be candidates for a total knee replacement procedure later in life if necessary. Your surgeon should discuss the specific risks associated with MAKOplasty and other treatment options with you.

Clinical Data Highlights

Results of several studies demonstrate the clinical benefits of robotic arm assisted MAKOplasty® Partial Knee Resurfacing. Initial results of an ongoing study found MAKOplasty resulted in more accurately placed implants and less pain for the first eight weeks after surgery when compared with patients receiving manually placed implants.
Comparing American Knee Society Scores, a common measure of knee functionality, the study also found MAKOplasty patients had increased post-operative functionality at three months post-surgery.

A study comparing MAKOplasty Partial Knee Resurfacing with total knee arthroplasty found that MAKOplasty demonstrated improved function, better post-operative range of motion, and better quadriceps strength.

Frequently Asked Questions

Q: Is MAKOplasty® covered by health insurance providers?
A: As a knee replacement procedure, MAKOplasty is typically covered by Medicare and most private insurance carriers.

Q: Does the robotic arm system actually perform the surgery?
A: No, MAKOplasty is performed by an orthopaedic surgeon, who uses the surgeon-controlled robotic arm system to pre-plan the surgery and to accurately resurface the bone with consistently reproducible precision.
The robotic arm does not perform the surgery nor can it make decisions on its own or move in any way without the surgeon guiding it. During surgery, 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.

Q: What is the difference between MAKOplasty and traditional knee replacement surgery?
B: Unlike manual surgery, MAKOplasty provides consistent and reproducible accuracy through the use of RIO and the contouring design of RESTORIS® implants. Compared to total knee replacements, MAKOplasty preserves healthy bone, soft tissue, and ligaments which allows for an overall less invasive procedure, more rapid recovery, shorter hospital stay, and more natural knee function.

Q: What is the lifespan of a MAKOplasty implant?
A: All implants have a life expectancy that depends on several factors including the patient’s weight, activity level, quality of bone stock, and compliance with their surgeon’s orders. Proper implant alignment and precise positioning during surgery are also very important.
