Further study details as provided by Medacta International SA:

Primary Outcome Measures:
  • Assessment of the clinical outcome following total hip replacement using the Harris Hip Score [ Time Frame: 6 months after surgery ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Assessment of the patient's physical level of activity using the Oxford Hip Score [ Time Frame: pre-op, annually post-op up to 10 years ] [ Designated as safety issue: No ]
  • Assessment of the improvement in quality of life and joint movement using the EuroQol-5D score [ Time Frame: pre-op, annually post-op up to 10 years ] [ Designated as safety issue: No ]
  • Assessment of implant survivorship as a measure of safety and tolerability [ Time Frame: 6 months, 3 years, 5 years, 7.5 years, 10 years after surgery ] [ Designated as safety issue: Yes ]
  • Assessment of the clinical outcome following total hip replacement using the Harris Hip Score [ Time Frame: pre-op, 6 months, 3 years, 5 years, 7.5 years, 10 years after surgery ] [ Designated as safety issue: No ]
