About the trial
What the trial wants to find out
The principal objective of this study is to compare mean 2-year subsidence of the ACTIS femoral stem using model-based RSA against published migration patterns for hip stems of a similar design. Secondary objectives include comparison of migration per surgical approach, quantifying changes in functional and health status of subjects following surgery, and assess occurrences of complications and adverse events.
