Over the years, knee replacement techniques and instruments have undergone countless improvements. MAKO Robotic-Arm Assisted Technology with Triathlon Total Knee implants is an example of how technology is transforming the way joint replacement surgeries are being performed.

When you hear “Robotic-Arm Assisted Technology”, it’s important to understand that the MAKO Robotic-Arm doesn’t actually perform the surgery. The surgery is performed by an orthopedic surgeon, who uses the MAKO System software to pre-plan your surgery. Your orthopedic surgeon will guide the MAKO Robotic_Arm to remove the diseased bone and cartilage. Then the surgeon will insert a Triathlon Joint Implant.

MAKO Technology was designed to help surgeons provide patients with a personalized surgical experience based on their specific diagnosis and anatomy.
