Description
Inclusion Criteria:
- Patients with symptomatic arthritis who are candidates for a primary total hip arthroplasty with an uncemented femoral stem as determined jointly by the surgeon and the patient.
- Patients suitable for an uncemented acetabular component in combination with a 36mm femoral head (seleXys PC cup: 52mm, 54mm or 56mm; RM Pressfit vitamys: 52mm, 54mm or 56mm)
- Patients between the ages of 50 and 75 inclusive
- Patients who understand the conditions of the study and are willing to participate for the length of the prescribed follow-up
