This multi-center, prospective, non-controlled, consecutive cohort post market surveillance study will serve the purpose of confirming long-term safety and performance of the Hyperion® system. The performance of the Hyperion® THA System will be evaluated using standard scoring systems (Merle d'Aubigné Score, Harris Hip Score, HOOS Score) and using documentation of sintering, wound healing and radiographic/clinical signs of loosening. Safety will be evaluated by adverse event reporting.
The study will be performed at 6 sites, enrolling in total 70 patients. Follow-up visits are planned after 3 to 6 month, 1, 2 and 5 years. The scores will be filled in pre-operatively and post-operatively until 5 years. In order to obtain mid- to long-term patient satisfaction data the patient questionnaire will be send to the patient at 7 and 10 years, additionally. Xrays will be done pre-operatively, immediate post-operatively and at each of the Follow-up visits.

- Pain and walking ability determined by a Merle d' Aubigné Score increase of >4 points. [ Time Frame: 2 years (+/- 2 month) ]Pain and walking ability determined by a Merle d' Aubigné Score increase of >4 points compared to the pre-operative score points determined by the inclusion criteria of a Merle d' Aubigné < 12 points.
- Implant survival measured by the number of revisions. [ Time Frame: 2 years (+/- 2 month) ]Implant survival is measured by the number of revisions and analysed by the Kaplan Meier method.
- Patient satisfaction measured by the WOMAC Scores and decrease in min. 25 points. [ Time Frame: 2 years (+/- 2 month) ]Patient satisfaction measured by the WOMAC Scores and decrease in min. 25 points compared to the pre-operative determined points (WOMAC Score > 25 points pre-operative)
