DJO’s new clinical study showed that EMPOWR 3D knee technology reduced patient dissatisfaction, and improved function and activity levels.
Based on a multitude of studies on the biomechanics and kinematics of the knee joint, and more than 10 years of clinical heritage with DJO’s 3D Knee, the EMPOWR 3D Knee is the industry’s first “dual-pivot” technology, a breakthrough concept that is designed to better replicate the natural motion and feeling of the healthy knee.
With nearly 700,000 procedures performed in the U.S. each year, total knee replacement surgery (TKR) is one of the most widely accepted and effective treatments for relieving degenerative osteoarthritis pain and suffering.
Unfortunately, nearly 20 percent of all patients – approximately 140,000 Americans each year1 – report they are not satisfied after their procedure, often claiming that their knee replacement “does not feel normal.”
EMPOWR 3D Knee is one of the most functionally accurate prostheses ever created. EMPOWR 3D Kne more closely recreates the natural dual-pivot motion pattern of the healthy knee throughout the entire range of motion, from early to deep flexion, creating a more natural feeling knee for the patient.1
Short term clinical results recently presented at the International Congress for Joint Reconstruction Hip and Knee Course in June 2018, demonstrate that the unique dual-pivot design of the EMPOWR 3D Knee® may offer far more natural motion for total knee arthroplasty (TKA) patients by more closely recreating the kinematics of a healthy human knee.2
The most significant clinical benefits of the EMPOWR 3D Knee® identified in the study include2:
Patient dissatisfaction is reduced by 50% compared to a competitive implant
Patient’s “knee feels normal” ~25% more often than with a competitive implant
Patients are over ~2X more active following surgery with the EMPOWR 3D Knee® versus a competitive knee implant
Indiana University School of Medicine orthopedic surgery associate professor Dr Michael Meneghini said: “Initial clinical results have been very encouraging for the EMPOWR 3D Knee.
“Patients with the EMPOWR 3D dual-pivot knee implant are experiencing improved knee function and showing a greater likelihood of a normal feeling knee.”
Dr. Scott Banks, PhD, Professor of Orthopedic and Joint Mechanics at the University of Florida, and Dr. Meneghini recently published an article in the journal Techniques in Orthopedics comparing the EMPOWR 3D Knee implant to traditional knee implant designs. They concluded that contemporary dual-pivot design and kinematics of the EMPOWR 3D Knee may contribute to improved function and satisfaction after TKR.
“Clinical studies over the past decade have shown that healthy knees have a much more complex front-to-back and side-to-side motion than previously believed,” said Banks.
“As a result, we now better understand why traditional knee arthroplasty designs have failed to accurately replicate normal knee activity and results in many patients feeling dissatisfied with their knee implant.
DJO Surgical global president jeffery McCaulley said: “EMPOWR 3D Knee patients tell us, ‘this knee just feels like my own.
“EMPOWR 3D Knee goes beyond clinical effectiveness to deliver one of the most functionally accurate knee implants based on our novel dual-pivot design that helps to improve patient outcomes and patient satisfaction.”
