Ten-year follow-up of a proximal circumferential porous-coated femoral prosthesis: radiographic evaluation and stability

Total hip arthroplasty with an uncemented hydroxyapatite-coated tapered titanium stem: results at a minimum of 10years’ follow-up in 104 hips

“…The improved retention most likely resulted from increased bone formation due to the coating and thereby increased load transfer between bone and implant. This phenomenon may explain why our results (IV, V), in terms of proximal bone resorption, compare favourably with the results after using an identical stem without HA-coating 126,172 . However, lack of exact radiological criteria must be considered when comparing different studies 116 .…”
