Medacta International products

Patient expectations are not as well fulfilled by TKA as by total hip replacement with fewer knee patients achieving a “forgotten joint” replacement.  Studies show that around 20% of TKA patients are not satisfied[^{1, 2, 3]}.  Excessive A/P motion may result in anterior knee pain and continued swelling. In many P/S designs, the stabilizing mechanism only engages after 70-80° of flexion leaving the knee vulnerable to A/P instability during the most commonly encountered functional activities.

In 2003 Medacta conceived  a simple, complete and homogeneous system for knee replacement. The GMK Primary System is conceived and designed adopting state-of-the-art solutions respecting the natural anatomy and kinematics of the knee joint.

Evolis implant and instruments have been developed in collaboration with a group of experienced orthopaedic surgeons making possible to successfully realize thousands of knee arthroplasties worldwide, including Europe, USA, Australia and Japan.
