Trochlear Ridge Arthroplasty
The self-explanatory Trochlea Ridge Arthroplasty implant covers the common indications of treatments in patella luxation in all breed sizes starting at 1,5 kg patient weight.
The system includes a wide range of sizes, in which three of the smallest sizes (# 1 to # 3) are also available in a broad version for covering an even wider range of indications.
The primary anchorage of the implant occurs via form fit and press fit, as well as via screw fixation.
The bone attached surface has an open-pored, lattice-shaped structure for optimal osteointegration.
The patellar contact surface is polished and DLC coated.
