About this study

Official title: Multi-Center Clinical Evaluation of the ATTUNE Cementless Rotating Platform Total Knee Arthroplasty

The primary objective of this study is to examine the change from pre-operative baseline to two year postoperative functional performance improvement for the ATTUNE primary, cementless TKA RP system as measured with the KOOS questionnaire (KOOS-ADL sub-score). This will be carried out for two configurations: cruciate retaining rotating platform (ATTUNE Cementless CR RP) and posterior stabilized rotating platform (ATTUNE Cementless PS RP).

Read the detailed description

The secondary objectives of this study are:

  • Evaluate change from preoperative baseline in post-operative outcomes using additional patient reported measures at 2 years: PKIP (overall and sub-scores), KOOS (overall and sub-scores), AKS and EQ-5D-3L.
  • Evaluate change from preoperative baseline in pain and satisfaction over time as measured using a modified VAS Pain Score (discrete numbers rather than a continual scale) at 2yr.
  • Evaluate type and frequency of Adverse Events
  • Evaluate survivorship of the ATTUNE Primary Cementless TKA system for the CR RP and PS RP configurations using Kaplan-Meier survival analysis at 2yr and 5yrs.
  • Evaluate primary, cementless ATTUNE TKA fixation through zonal radiographic analysis of the bone-implant interface at 6wk, 6mo, 1yr, and 2yr after surgery.
  • Evaluate any changes in anatomic tibiofemoral, femoral component and tibial component alignment at 2 years compared to the first postoperative radiographs.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Patient-reported Outcome: Knee Injury and Osteoarthritis Outcome Score Activities of Daily Living (KOOS ADL)

    The Knee injury and Osteoarthritis Outcome Score (KOOS) is a patient self-administered questionnaire that consists of 42 questions and include the WOMAC Osteoarthritis index. The KOOS consists of 5 subscales: pain, other symptoms, activities of daily living (ADL), sport and recreational function and knee related quality of life. Each question has 5 Likert-like response options. A normalized score (100 indicating no symptoms and 0 indicating extreme symptoms) is calculated for each subscale.

    Measured: Minimum 2 years (670-1033 days after surgery)

Secondary outcomes (13)
  1. Patient-reported Outcome: Pre-surgical/Post-surgical Patient's Knee Implant Performance (PKIP)

    The Pre Surgical and/or Post-surgical Patient's Knee Implant Performance (PKIP) questionnaire is a patient self-administered questionnaire that consists of 25 questions relating to the patient's awareness of their knee. Questions include the patient's self-confidence about the current status of their knee performance, stability, and overall satisfaction. Each question has a 5, 6 or 10 Likert- like response option.

    Measured: Minimum 2 years (670-1033 days after surgery)

  2. Patient-reported Outcome: Knee Injury and Osteoarthritis Outcome Score (KOOS)

    The Knee injury and Osteoarthritis Outcome Score (KOOS) is a patient self-administered questionnaire that consists of 42 questions and include the WOMAC Osteoarthritis index. The KOOS consists of 5 subscales: pain, other symptoms, activities of daily living (ADL), sport and recreational function and knee related quality of life. Each question has 5 Likert-like response options. A normalized score (100 indicating no symptoms and 0 indicating extreme symptoms) is calculated for each subscale.

    Measured: Minimum 2 years (670-1033 days after surgery)

  3. Combination of Patient-reported and Clinical-reported Outcome: Knee Society 2011

    The Knee Society Score is a self-administered questionnaire. The subject completes questions regarding: Symptoms (3 questions), Patient Satisfaction (5 questions), Patient Expectations (3 questions), Functional Activities (5 questions), Standard Activities (6 questions), Advanced Activities (5 questions), and Discretionary Knee Activities ( 4 questions). The surgeon completes questions regarding objective knee indicators. Likert responses are used, typically with five response options.

    Measured: Minimum 2 years (670-1033 days after surgery)

  4. Patient Reported Outcome: EuroQol 5D 3L questionnaire (EQ-5D-3L)

    EuroQol 5D 3L questionnaire is a standardized instrument for use as a measure of health outcome that is designed for completion by the subject.

    Measured: Minimum 2 years (670-1033 days after surgery)

  5. Modified VAS Pain Score: Pain and Satisfaction

    VAS Pain Score is a standardized instrument for use as a measure of pain and satisfaction that is designed for completion by the subject. This modified version has scores that are discrete numbers rather than a continual scale

    Measured: Minimum 2 years (670-1033 days after surgery)

  6. Type and Frequency of Adverse Events (AEs) for all enrolled subjects

    All Serious AEs must be reported to Sponsor. All device-related or procedure-related adverse events must be reported to Sponsor.

    Measured: Pre-op (-90 to -1 days before surgery), 6 weeks (1-90 days after surgery), 6 months (91-303 days after surgery), minimum 1 year (304-669 days after surgery), minimum 2 years (670-1033 days after surgery), minimum 5 years (1764-2190 days after surgery)

  7. Survivorship

    Kaplan-Meier survival analysis will be used to calculate the survivorship of all 2 configurations (CR RP, PS RP)

    Measured: Minimum 2 years (670-1033 days after surgery)

  8. Survivorship

    Kaplan-Meier survival analysis will be used to calculate the survivorship of all 2 configurations (CR RP, PS RP)

    Measured: Minimum 5 years (1764-2190 days after surgery)

  9. Implant fixation: Radiographic assessment of bone-implant interface performance

    Radiographic success is defined as: absence of progressive radiolucent lines greater than or equal to 2mm in any one zone; absence of lytic lesions in any zone; absence of individual component position change >3degrees in any plane.

    Measured: 6 weeks (1-90 days after surgery)

  10. Implant fixation: Radiographic assessment of bone-implant interface performance

    Radiographic success is defined as: absence of progressive radiolucent lines greater than or equal to 2mm in any one zone; absence of lytic lesions in any zone; absence of individual component position change >3degrees in any plane.

    Measured: 6 months (91-303 days after surgery)

  11. Implant fixation: Radiographic assessment of bone-implant interface performance

    Radiographic success is defined as: absence of progressive radiolucent lines greater than or equal to 2mm in any one zone; absence of lytic lesions in any zone; absence of individual component position change >3degrees in any plane.

    Measured: Minimum 1 year (304-669 days after surgery).

  12. Implant fixation: Radiographic assessment of bone-implant interface performance

    Radiographic success is defined as: absence of progressive radiolucent lines greater than or equal to 2mm in any one zone; absence of lytic lesions in any zone; absence of individual component position change >3degrees in any plane.

    Measured: Minimum 2 years (670-1033 days after surgery)

  13. Evaluate changes in femoral component and tibial component alignment

    Radiographs will be reviewed by an independent radiographic reviewer (IRR) in order to minimize bias of radiographic outcomes. Data from the IRR radiographic evaluations will be used to evaluate femoral and tibial component alignment over time.

    Measured: Minimum 2 years (670-1033 days after surgery)
