The purpose of this study is to monitor the performance of the DeltaMotion cup system in the treatment of patients with hip joint disease requiring a total hip replacement.Patients who enter the study will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments.

Condition Intervention Phase
Rheumatoid Arthritis Osteoarthritis Post-traumatic Arthritis Avascular Necrosis Traumatic Femoral Fractures Congenital Hip Dysplasia Device: Delta Motion Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Multi-centre, Prospective, Uncontrolled Post Market Clinical Follow-up Study (PMCFS) to Monitor the Survival and Performance of the DeltaMotion Cup System in Subjects Requiring a Total Hip Replacement

Further study details as provided by DePuy International:

Primary Outcome Measures:
  • Kaplan-Meier survivorship [ Time Frame: 3 years ]
    To determine survivorship of the DeltaMotion Cup System at 3 years

Secondary Outcome Measures:
  • Kaplan-Meier survivorship [ Time Frame: 10yrs post-surgery ]
    To determine survivorship of the DeltaMotion Cup System at 10 years

  • Harris Hip Score [ Time Frame: 10yrs post-surgery ]
    Change from baseline in the Harris Hip Score. The Harris Hip Score is used to measure the outcome of total hip replacement and covers the areas of pain, function, absence of deformity and range of motion.

  • Oxford Hip Score [ Time Frame: 10yrs post-surgery ]
    Change from baseline in the Oxford Hip Score. The Oxford hip score is a patient completed outcomes score which is designed to assess function and pain with patients undergoing hip replacement surgery.

  • University of California Los Angeles (UCLA) Score [ Time Frame: 10yrs post-surgery ]
    Change from baseline in the UCLA Quality of Life Score. UCLA is a patient completed outcome score used in hip replacement

  • Western Ontario and McMaster Universities (WOMAC) Score [ Time Frame: 10yrs post-surgery ]
    Change from baseline in the WOMAC. WOMAC is a patient complete outcome score to assess pain, disability and joint stiffness in Osteoarthritis of the hip and knee

  • Radiological analysis [ Time Frame: 10yrs post-surgery ]
    • Acetabular Migration (vertical or horizontal) less than 5mm
    • Acetabular Migration (varus or valgus) less than 5 degrees
    • No loosening - absence of acetabular radiolucencies of greater than 2mm in two zones.

Estimated Enrollment: 250
Actual Study Start Date: July 1, 2012
Estimated Study Completion Date: March 1, 2024
Estimated Primary Completion Date: December 31, 2019 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Delta Motion
A cementless acetabular cup with a pre-assembled ceramic liner for use in total hip replacement
