Outcome Measures

Primary Outcomes (1)

  • KOOS-PS change from baseline at 6 months post-operatively, as estimated from a repeated measurements longitudinal model over all post-operative time points.

    The Knee Injury and Osteoarthritis Physical Function Short Form (KOOS-PS) will be used to measure knee function as a means of evaluating the rate of recovery. The (KOOS-PS) is a patient self-administered questionnaire. The questionnaire consists of 7 questions to evaluate function with activities of daily living (ADL) and higher level functioning activities (sport and recreational). Each question has 5 Likert-like response options. Scoring is a 0-100 point scale with 100 points considered best.

    6 Months Post-Operative minus Pre-Op

Secondary Outcomes (4)

  • KOOS-PS change from baseline of the ATTUNE knee

    Pre-Op (-90 days to day of surgery), 6 weeks (1 - 60 days), 3 months (61 - 137 days), 1 year (304 - 669 days), and 2 years (670 - 913 days) post-operative

  • Length of Hospital Stay

    Immediate-post-operative: average 1 week

  • Annual Survivorship

    1 year (304 - 669 days), 2 years (670 - 913 days) post-operative

  • Type and frequency of Adverse Events (AEs) for all enrolled subjects

    Day 0 - Post-Operative Day 913

Study Arms (1)

ATTUNE Primary, Cemented Total Knee Replacement

Subjects will receive one of four available ATTUNE total knee implants: (CR FB, CR RP, PS FB, PS RP).

Device: ATTUNE Primary, Cemented Total Knee Replacement

Interventions

Patients will undergo a primary total knee replacement using one of the four implant configurations of the ATTUNE knee ( CR FB, CR RP, PS FB, PS RP).
