This prospective study will evaluate the hip function and quality of life of patients operated for total hip arthroplasty with Masterloc femoral stem and MPACT acetabular cup. The results of this study will establish the performance of Masterloc femoral component (Medacta International SA) and MPACT acetabular component (Medacta International SA), and provide a general estimate of survivorship, clinical effectiveness and complications.
