|Condition or disease||Intervention/treatment|
|Arthroplasty, Replacement, Hip||Device: aneXys|
Prospective observational multicenter case series providing short-term migration results and long-term post-market clinical data on the safety and performance of the aneXys cup. The study includes patients undergoing primary total hip arthroplasty. In total 150 patients in 3 clinics will be included. In each clinic 50 consecutive patients shall be included. In addition, to meet the regulatory requirements, a total of minimum 20 cases with screw fixation shall be included in the study.
Clinical and radiological follow-up (FU) is planned after 6-12 weeks, 6 months, 1, 2, 5, 7 and 10 years. An additional FU at 3 years is planned to apply for an ODEP (Orthopaedic Data Evaluation Panel) rating.

cases with aneXys cup and Mathys hip stem
150 patients with the aneXys cup
- Cup migration after 2 years [ Time Frame: 2 years ]The primary endpoint will be the radiographic evaluation of the acetabular cup migration based on performed EBRA measurements 2 years after surgery.
- Harris Hip Score [ Time Frame: 10 years ]The secondary endpoint will be the determination of the clinical outcome using the Harris Hip Score.
- Visual analogue scale vor pain [ Time Frame: 10 years ]The secondary endpoint will be the determination of the clinical outcome using the Visual analogue scale for pain.
- Visual analogue scale for satisfaction [ Time Frame: 10 years ]The secondary endpoint will be the determination of the clinical outcome using the Visual analogue scale for satisfaction.
- The Western Ontario and McMaster Universities Osteoarthritis Index [ Time Frame: 10 years ]The secondary endpoint will be the determination of the clinical outcome using the WOMAC.
- Osteolysis [ Time Frame: 6-12 weeks - 10 years ]The first endpoint of interest is the occurrence of osteolysis around the cup.
- Lucent lines [ Time Frame: 6-12 weeks - 10 years ]The second endpoint of interest is the occurrence of lucent lines around the cup.
- Complications [ Time Frame: post-op - 10 years ]The first safety endpoint will be the number of complications with respect to the investigational product.
- Revisions [ Time Frame: post-op - 10 years ]The second safety endpoint will be the number revisions with respect to the investigational product.
