The HA-coated ABG socket in revision arthroplasty

The favourable results we achieved in primary THR with the ABG HA-coated hemispheric metal backed cup led us to use this same cup in revision arthroplasty. Changes in inclination and migration of the cup were measured, as well as the radiologic appearance of the bone-cup interface. The most important features are quick osseointegration and immediate stability. The early and three to five years results with the use of the ABG HA-coated cup in revision arthroplasty are promising.
