About this trial

This is an interventional treatment trial for Hip Joint focused on measuring total hip replacement, roentgen stereophotogrammetric analysis

Eligibility Criteria

50 Years - 75 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

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

Exclusion Criteria:

  • Patients that require an acetabular cup size which cannot be used in combination with a 36mm femoral head
  • Patients that offer no guarantee for regular follow-up controls
  • Patients that have a revision surgery
  • Patients that have a fracture of the femoral neck or a bone tumour in the area of the femur or pelvis
  • Patients that had a previous osteotomy of the femur or pelvis
  • Pregnant women or those seeking to become pregnant
  • Patients with a history of active infection

Primary Outcome Measures

Wear Rate
The principal purpose of this study is to compare the modular seleXys PC Cup with a vitamys inlay to the monoblock RM Pressfit vitamys cup by means of wear rate. In addition, the migration of the two cups and the optimys stem, respectively, will be evaluated.
