Brief summary
The purpose of the study is the evaluation of the clinical and radiological short- to long-term safety and performance of the RM Pressfit vitamys cup. The data will be used for an ongoing evaluation of the product safety and performance.
Detailed description
Prospective multicenter follow-up study which examines the short- to long-term post-market clinical data on the safety and performance of the RM Pressfit vitamys cup. In total 675 participants in 9 clinics are included in this international multicenter study. The primary endpoint of the study is the Harris Hip Score (HHS) 2 years after surgery. The following parameters will be collected during the regular clinical and radiological follow-up: Harris Hip Score, radiographic evaluation and detection of adverse events.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Harris Hip Score (modified after Haddad et al, 1990) | 2 years | The primary endpoint of the study is the Harris Hip Score (HHS) 2 years after surgery. The HHS is a measure of dysfunction so the higher the score, the better the outcome for the individual. The maximum score possible is 100. Results can be interpreted with the following: \<70 = poor result; 70-80 = fair, 80-90 = good, and 90-100 = excellent. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Radiographic evaluation | 6-12 weeks - 10 years | The second endpoint of interest is the occurence of osteolysis around the cup |
| Adverse Events | 6-12 weeks - 10 years | Reporting of Adverse Events |
