AAOS: Stryker Launches Mako Robotic-Arm Assisted Total Knee Application

Stryker Corporation announced the commercial launch of the highly anticipated robotic-arm assisted total knee arthroplasty application for use with its Mako System at the American Academy of Orthopaedic Surgeons (AAOS) annual meeting in San Diego, Calif. This latest advancement distinguishes the Mako System as the first and only robotic technology that can be used across the joint replacement service line to perform total knee, total hip and partial knee replacements.
 
Mako Total Knee combines Stryker’s advanced robotic technology with its clinically proven Triathlon Total Knee System (“GetAroundKnee”), enabling surgeons to have a more predictable surgical experience with increased accuracy.¹ Through CT-based 3D modeling of bone anatomy, surgeons can use the Mako System to create a personalized surgical plan and identify the implant size, orientation and alignment based on each patient’s unique anatomy.  The Mako System also enables surgeons to virtually modify the surgical plan intra-operatively and assists the surgeon in executing bone resections.
 
Total knee replacements in the United States are expected to increase 673 percent by 2030,² yet studies have shown that approximately 30 percent of patients are dissatisfied after conventional surgery.³ As this procedural growth materializes, surgeons will continue to seek clinical solutions that leverage technological advancements to improve their patient’s satisfaction.
 
“We are excited to be leading the transformation of the orthopedics industry with the commercial launch of the Mako Total Knee application,” said Bill Huffnagle, president of Stryker’s Joint Replacement Division. “We believe that pairing our Mako robotic-arm technology with our market leading implant systems will enable surgeons to have an improved surgical experience.”
 
More than 83,000 Mako robotic-arm assisted procedures, including total knee, partial knee and total hip replacements, have been performed through 2016.  More than 350 Mako Systems have been placed in the United States with over 1,400 Mako Total Knee replacements performed to date.
 
Stryker will showcase its latest technologies, including Mako, at AAOS (booth #3133) from March 15-17, 2017.
