Resumen (ES)
This study was aimed at evaluating the outcome in terms of primary bone fixation
of a total hip prosthesis coated with Poropatita®, o double coating of porous-metal and hidroxyapatite.
The study reviews 80 patients operated on with a minimum follow-up of 3 years.
A modified Harris score was used for clinical assessment. Good clinical results wer obtained in
90% of patients, while 10% achieved a fair outcome. Based on clinical and radiographic parameters,
porous-metal and hidroxyapatite double coating provides both excellent primary and
secondary bone fixation of the prosthetic components. Primary stability of both femoral stem
and cup seens to be an important factor for osteointegration of the implant.
