At Orthopedic & Sports Institute of the Fox Valley (OSI), innovation meets expertise. As the first in Northeast Wisconsin to offer Mako Robotic-Arm Assisted Surgery™, OSI continues to lead the region in advanced orthopedic care.
Whether you’re considering a partial or total knee replacement, or a partial or total hip replacement, OSI’s board-certified orthopedic surgeons harness cutting-edge robotic technology to optimize every step of your procedure.
It all begins with a series of X-rays or CT scans to create a detailed 3D model of your joint. This model enables your OSI surgeon to plan the procedure with pinpoint precision—calculating exact joint dimensions and determining precisely how much bone to remove.
During surgery, the robotic arm provides real-time tactile, visual, and auditory feedback, helping your surgeon achieve optimal implant positioning and alignment.
OSI’s commitment to combining state-of-the-art technology with decades of orthopedic experience means you’ll receive care that’s not only advanced—but also deeply personal. From diagnosis to recovery, we’re here to help you move better, feel stronger, and get back to the life you love.

Frequently asked questions
What is Mako?
Stryker’s Mako Robotic Arm Assisted Surgery is the next generation of robotic surgery and joint replacement. The robot offers a higher level of customization and accuracy for implant alignment and positioning within a total hip, total knee, or partial knee replacement.
How do I set up surgery?
Request an appointment with one of Orthopedic & Sports Institute of the Fox Valley’s Mako-certified doctors to see if a Mako Total Hip, Total Knee, or Partial Knee robotic-arm assisted surgery is right for you.
Call us today to request an appointment for your consultation at (920) 560-1000.
What are the advantages of the Mako robot?
The Mako technology allows OSI surgeons to create a patient-specific 3D plan that uses a CT scan to guide the total hip, total knee, or partial knee reconstruction plan, taking into account each patient’s specific anatomy and ligament balance. The OSI surgeon guides the Mako Robotic-Arm within the predefined area, and the Mako System helps the surgeon stay within the planned boundaries that were defined in the patient-specific, pre-operative plan to complete the surgery. The computer-navigated surgery also protects the patient against soft-tissue damage with its high level of accuracy.
Who should get the surgery with Mako Technology?
Total hip, total knee, and partial knee replacement is intended for use in individuals with joint disease resulting from degenerative, rheumatoid, and post-traumatic arthritis. It is also intended for those suffering from moderate deformity of the knee or hip.
Schedule a consultation with your OSI doctor to see if the Mako total hip, total knee, or partial knee robotic-arm assisted surgery is right for you.

Is Mako covered by health insurance?
Please check with your health insurance provider to verify your specific coverage.
How long has the Mako procedure been available?
The first Mako procedure was a partial knee replacement performed in June 2006. Since that time, more than 83,000 Mako hip and knee replacement procedures have been performed around the world.
Does the Mako Robotic-Arm actually perform the surgery?
It’s important to understand that the Mako Robotic-Arm doesn’t actually perform surgery. Surgery is performed by your OSI orthopedic surgeon, who uses the Mako System software to pre-plan your surgery. During surgery, the Mako System helps your surgeon stay within the planned boundaries that were defined in your personalized, pre-operative plan. Your OSI knee or hip surgeon will guide the Mako Robotic Arm to remove diseased bone and cartilage. Then the surgeon will insert the full or partial knee or hip replacement.
How long do knee implants last?
Each person is unique in their anatomy and recovery time; not all patients will have the same postoperative recovery and activity level. The lifetime of a knee or hip replacement is not infinite and varies with each individual person.
What can I expect after Mako Robotic-Assisted surgery?
After Mako surgery, your OSI surgeon, nurses and physical therapists will set goals with you to get you back on the move. They will closely monitor your condition and progress. Your OSI surgeon may review a post-operative X-ray of your new knee with you.
Where is the surgery performed?
The Mako Robotic-Arm surgery is performed at OSI’s main campus, 2105 E. Enterprise Ave., Appleton, WI 54913
