Medacta Highlights MasterLoc Hip System and GMK Sphere Knee at American Association of Hip and Knee Surgeons Annual Meeting

November 10, 2016

CHICAGO & DALLAS, Texas–(BUSINESS WIRE)–Medacta International, the privately held family-owned global leader in the design of innovative joint replacement and spine surgery products, announced it will showcase its new MasterLoc™ Hip System and GMK®Sphere Knee at the 26th American Association of Hip and Knee Surgeons (AAHKS) Annual Meeting, held November 10-13, 2016 in Dallas, Texas.

“Medacta’s commitment to surgical innovation is on display at this year’s AAHKS Annual Meeting, including our new MasterLoc cementless tapered wedge implant,” said Francesco Siccardi, Executive Vice President of Medacta International. “The launch of MasterLoc brings Medacta into the proximally coated, flat tapered wedge hip market and allows us to provide yet another option for our surgeon partners considering minimally invasive hip replacement.”

MasterLoc Hip System – 40 Years of Clinical Evolution

The MasterLoc Hip System is the newest addition to the company’s cementless implant portfolio. The implant features Medacta’s Mectagrip plasma-sprayed titanium coating, designed to enhance initial fixation due to its high coefficient of friction and the potential long-term stability inherent to titanium plasma-sprayed devices.

The MasterLoc cementless tapered wedge implant is the result of 40 years of clinical evolution since initial designs were described in the 1970s. The MasterLoc was designed to be implanted through all minimally invasive, muscle-sparing techniques, including Medacta’s Anterior Minimally Invasive Surgery (AMIS®) technique. It can also be coupled with any of Medacta’s acetabular products, including the recently announced Mpact® Double Mobility Acetabular System.

GMK Sphere Knee – 20,000 Implants To-Date

Medacta’s GMK Sphere is an innovative primary total knee system designed to deliver maximum functional stability along with patient-specific kinematics to improve patient satisfaction. In the past five years, more than 20,000 GMK Sphere Knees have been implanted worldwide.

“The GMK Sphere has become our most popular knee product, capturing over half of Medacta’s knee business,” continued Siccardi. “The surgeon and patient feedback we’ve received has been incredibly encouraging and we look forward to even more success ahead.”

In addition to the MasterLoc Hip System and GMK Sphere Knee, Medacta will also be showcasing its recently launched GMK®Efficiency Single Use Knee Instruments, Mpact Double Mobility Acetabular System and GMK® Revision Knee System, along with its entire hip and knee portfolio.
