Peri-ApatiteTM Enhances Prosthetic Fixation in Tka-A Prospective Randomised RSA Study
Author(s): Mats Molt and Soren Toksvig-LarsenMats Molt and Soren Toksvig-Larsen
Objectives: The success of non-cemented knee fixation relies on the initial stability of the components. The application of ceramic coatings such as hydroxyapatite (HA) to the implant shortens the time needed to achieve adequate prosthetic fixation. The purpose of this study was to determine whether a low temperature precipitation technique, Peri-Apatite™ HA coating, reduces three-dimensional migration compared with porous coated press-fit tibial components.
Methods: Sixty patients were prospectively randomised to receive either a Peri-Apatite™ or a porous coated version of the same knee prosthesis type. Three-dimensional tibial component migration was measured by radiostereometric analysis (RSA) at three months, one year and two years; clinical outcome was measured by the American Knee Society Score (AKSS) and Knee Osteoarthriti..
