Brief Summary: This study was designed to investigate the influence of HA-coating on bone remodeling around the cup in cementless THA

100 patients gave informed consent to participate in a controlled randomized study between porous coated Trilogy versus Trilogy Calcicoat The cup was inserted in press-fit fixation The femoral component was a cementless porous coated titanium alloy stem Bi-Metric with a modular 28 mm CrCo head Effect parameters were Harris Hip Score HHS and Bone Mineral Density BMD determined by DEXA scanning

Measurements revealed no difference between the two groups after 3 years neither in clinical outcome nor in terms of periprosthetic bone density Patients with Body Mass Index above normal regained more bone mineral than patients with normal weight This finding supports the assumption that load is beneficial to bone remodeling Advantages of better sealing of the bone-prosthesis interface preventing polyethylene induced osteolysis may still be anticipated for the 7 or 12 year follow-up examinations
