Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change in Western Ontario and McMasters University Osteoarthritis Index (WOMAC) Pain Score from baseline [ Time Frame: Change at 24 months relative to baseline ]
    The WOMAC Pain score is derived from a sub-section of the Knee injury and Osteoarthritis Outcome Score (KOOS) Knee Survey. The WOMAC Pain scores range from 0-100 with lower scores considered lower pain.

  2. Change in Western Ontario and McMasters University Osteoarthritis Index (WOMAC) Function Score from baseline [ Time Frame: Change at 24 months relative to baseline ]
    The WOMAC Function score is derived from a sub-section of the Knee injury and Osteoarthritis Outcome Score (KOOS) Knee Survey. The WOMAC Function scores range from 0-100 with lower scores considered to have better function.

  3. Incidence of Treatment-Emergent Adverse Events resulting in Secondary Surgical Interventions [ Time Frame: From baseline to 24 months ]
    Incidence of Secondary Surgical Intervention due to implant related Adverse Events

  4. Maintenance of Implant Integrity by Radiographic Review [ Time Frame: From baseline to 24 months ]
    Implant integrity will be assessed by radiographic review to verify that the implant is not disassembled
