OrthoVirginia’s Herndon Operatory Now Offering Highly Advanced Robotic-Arm Assisted Knee Replacement Procedures With Stryker’s Mako System

Innovative Robotic Technology Allows Surgeons to Personalize Procedures to Each Patient in an Outpatient Setting

Fairfax, VA, July 15, 2020 – OrthoVirginia’s Herndon Operatory is the first outpatient surgical suite in Virginia to offer robotic-arm assisted total knee and partial knee with Stryker’s Mako System. This highly advanced robotic technology transforms the way joint replacement surgery is performed, enabling surgeons to have a more predictable surgical experience with increased accuracy^1,2,3,4.

Total knee replacements in the United States are expected to increase 673 percent by 2030,⁷ yet studies have shown that approximately 30 percent of patients are dissatisfied after conventional surgery⁶. Mako Total Knee combines Stryker’s advanced robotic technology with its clinically proven GetAroundKnee (Triathlon Total Knee System), which has enabled surgeons to have a more predictable surgical experience with increased accuracy during laboratory testing⁷.

“With Mako, we can provide each patient with a personalized surgical experience based on their specific diagnosis and anatomy,” said Dr. George Aguiar of OrthoVirginia. “Using a virtual 3D model, Mako allows surgeons to create each patient’s surgical plan pre-operatively before entering the operating room. During surgery, we can validate that plan and make any necessary adjustments while guiding the robotic-arm to execute that plan. It’s exciting to be able to offer this transformative technology across the joint replacement service line to perform total knee and partial knee replacements.”

The Mako Total Knee application is a knee replacement treatment option designed to relieve the pain caused by joint degeneration due to osteoarthritis. 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.

The Mako Partial Knee application is a treatment option designed to relieve the pain caused by joint degeneration due to osteoarthritis that has not yet progressed to all three compartments of the knee. Following the personalized pre-operative plan, the surgeon guides the robotic-arm during bone preparation to execute the pre-determined surgical plan and position the implant. By selectively targeting only the part of the knee damaged by osteoarthritis, surgeons can resurface the diseased portion of the knee, while helping to spare the healthy bone and ligaments surrounding the knee joint. Studies have shown robotic-arm assisted partial knee replacement to be two to three times more accurate than manual partial knee replacement procedures^8,9,10.

“We are proud to be the first outpatient operatory in Virginia to offer this highly advanced robotic technology in our area,” said Justin Zakia, Chief Administrative Officer of OrthoVirginia – Northern Virginia. “The addition of Mako to our practice further demonstrates our commitment to provide the community with outstanding healthcare.”
