Outcome measures
Primary outcome
Radiographic analysis with roentgen stereophotogrammetry analysis focussing on stem migration, bone remodelling, implant ingrowth
Secondary outcome
- Harris Hip Score (HHS)
- HOOS
- SF-12
Background summary
Stability of an implant is achieved during surgery (primary stability) and will increase afterwards (secondary stability). Press-fit ensures primary stability of cement-less components. Due to the favourable biomimetic properties, nanotechnology BoneMaster® coating is expected to enhance faster ingrowth.
Study objective
We hypothesise that the Taperloc BoneMaster coated stem is equal or better than conventional porous coated or cemented stem focussing on implant ingrowth and bone remodelling.
Study design
- follow-up at 1 and 5 years
- measurements at 0, 6wks, 3mnths, 6 mnths, 1yr, 2yr and 5yr
Intervention
- BoneMaster I
Randomisation in placement of a conventional Taperloc stem or the Taperloc BoneMaster® coated stem
- BoneMaster II
Randomisation in placement of a conventional Taperloc stem or the Taperloc BoneMaster® coated stem or cemented Taperloc stem.
