Hydroxyapatite (HA) coatings have become very popular in uncemented total hip
arthroplasty (THA). Analysis of retrievals and tissue samples from an HA-coated femoral …

This study reports on the results of the implant and tissue analysis of clinically retrieved
hydroxyapatite (HA)-coated implants. Five of the patients with fixed HA-coated stems had …

Hydroxyapatite (HA) has been widely used as a coating for orthopedic metal implants. An
important concern regarding HA coating is its degradation of the biological milieu. In this …

We performed a histological and histomorphometric examination in five cadaver specimens
of the femoral and acetabular components and the associated tissue which had been …

Bone reactions were studied around a titanium, hydroxyapatite (HA)-coated Osteonics
(Allendale, NJ) bipolar hip prosthesis, which was revised for severe midthigh pain 4 years …

Studies of implant fixation have shown that hydroxyapatite (HA) coatings provide early and
strong fixation to bone. This is a report of 100 consecutive cases of total hip arthroplasties …

ABSTRACT PURPOSE OF THE STUDY Hydroxypatite coating (HAC) was introduced into
total hip arthroplasty (THA) practice to improve the fixation interface between bone and …

We assess 254 consecutive primary total hip replacements (THRs) using a fully
hydroxyapatite (HA)-coated stem and socket (Furlong; JRI, London, UK). Minimum follow-up …

A 61-year-old woman fitted with a hydroxyapatite (HA)-coated macrotexture all-purpose hip
prosthesis died three weeks after implantation. The retrieved femoral and acetabular …

When John Chamley pioneered total hip arthroplasty (THA) more than 30 years ago, fixation
and wear of the components were the two major challenges he faced; these two problems …
