From pioneering to proven

We are thrilled to announce the launch of our upcoming campaign «From pioneering to proven», celebrating in 2023 the remarkable success of some of our key products. This year marks significant milestones for four of our groundbreaking products: the 40th anniversary of the RM Cup, the 25th anniversary of balanSys BICONDYLAR, the 20th anniversary of balanSys UNI, and the 15th anniversary of Affinis Fracture Inverse.

RM Pressfit

With 40 years of clinical experience, Mathys is proud to showcase the evolution of its hero product, the isoelastic, bone preserving, monoblock acetabular RM Pressfit cup. The cup's isoelasticity and RM coating places it in a class of its own, as an unmatched design that has evolved in proven steps, from a non-coated cementless PE acetabular cup to the addition of hydroxyapatite and later to its RM single titanium particle coating. The RM Pressfit vitamys cup, the latest iteration of the cup, remains unquestionably impressive after 40 years of clinical experience with this isoelastic philosophy. The ongoing excellent performance is proven by clinical results1,2.
