Implant fixation is of utmost importance for pain-free function of endopros
theses. Primary fixation is achieved during implantation, whereas secondary
fixation is a result of repair and bone remodelling during the healing pro
cess comparable to fracture healing. The chronologic course of the healing
process follows three overlapping phases: (i) an initial phase with destruc
tion and necroses of bone, (ii) a phase of repair with integration of the i
mplant into the bone, and (iii) a phase of stabilization of the permanent i
mplant bed with adaptation to load transfer and possible reactions to irrit
ations of the interface like sepsis, mechanical instability, corrosion and
degradation of implant materials, and wear products from articulating and a
nchoring surfaces.
