Abstract

We investigated hydroxyapatite (HA)-coated metal implants to improve the fixation of cementless total hip replacements (THR). We found postoperative thigh pain in 30.7% (46/150 joints) of Harris Galante Porous (HGP) type THR and 5% (1/20 joints) of HA-coated THR. HA-coatedtitanium sprayed Ti-6Al-4V might improve the fixation of HA-coated THR in which HA was coated onto the flat Ti-6Al-4V.
