Alpina

The total knee prosthesis Alpina was developed by the surgeons of the ORA group (Orthopédie Rhône Alpes – group of 17 surgeons) and launched on the market in 1992.The Alpina prosthesis philosophy is to reconstruct the knee joint by closely matching the original anatomy prior to damage.

Features

  • Real anatomic prosthesis with asymetric condyles allowing the rotation during the anatomic flexion
  • The condyles are divergent distally, parrallel posteriorly, arched towards the intercondylar notch, significantly increasing surface contact and reducing cold flow and wear
  • Modular prosthesis allowing to use the CR version and the PS version without additional bones cuts
  • For the PS version, the postero-stabilization mechanism uses an intercondylar cam articulating with a groove in the polyethylene insert. The came engages at 45° of flexion
  • 5 sizes of condyles in CoCr cemented et cementless ( with HA)
  • 6 sizes of tibial baseplates in CoCr (cemented) or in TA6V + HA (cementless)
  • Tibial bearing in PE ArCom® for minimal wear
  • Stable fixation of the implants
  • Simple and precise instrumentation allowing a reproductible and reliable technique
