NCT01746524

Brief Summary

This post-marketing investigation will evaluate the functional knee performance of Subjects who have undergone primary total knee arthroplasty (TKA). Data from Subjects who receive one of four contemporary knee configurations will be pooled to establish a contemporary dataset. The primary objective of this study is to evaluate the pre-operative (approximately -90 to -1 day before surgery) to minimum one year (approximately 304 to 668 days) postoperative functional performance improvement for the Attune™ primary, cemented TKA system as measured by the activities of daily living (ADL)subscore of the Knee Osteoarthritis Outcomes Score (KOOS)questionnaire (KOOS-ADL sub-score). This will be carried out for all four implant configurations: cruciate retaining fixed bearing (Attune™ CR FB), cruciate retaining rotating platform (Attune™ CR RP), posterior stabilized fixed bearing (Attune™ PS FB), and posterior stabilized rotating platform (Attune™ PS RP).

Outcome Measures

Primary Outcomes (1)

  • Knee Injury and Osteoarthritis Outcome Score (KOOS) activities of daily living (ADL) sub-score change from baseline.

    The KOOS ADL will be measured before surgery and at a minimum 1 year after surgery. The KOOS is a patient self-administered questionnaire that consists of 42 questions. 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. The change from baseline is the minimum 1 year (approximately 304 to 668 days) measurement minus the baseline measurement.

    One year or later (approximately 304 days or later)

Secondary Outcomes (11)

  • Patient Reported Outcome: Oxford Knee Score (OKS)

    Pre-op (-90 to -1 days before surgery), < 1 year (1 to 303 days), minimum 1 year (304 to 668 days), minimum 2 year (669 to 1763 days)

  • Patient Reported Outcome: Pre-surgical/Post-surgical Patient's Knee Implant Performance (PKIP)

    Pre-op (-90 to -1 days before surgery), < 1 year (1 to 303 days), minimum 1 year (304 to 668 days), minimum 2 year (669 to 1763 days)

  • Patient Report Outcome: EuroQol 5D 3L questionnaire (EQ-5D-3L)

    Pre-op (-90 to -1 days before surgery), < 1 year (1 to 303 days), minimum 1 year (304 to 668 days), minimum 2 year (669 to 1763 days)

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

    < 1 year (1 to 303 days), minimum 1 year (304 to 668 days), minimum 2 year (669 to 1763 days)

  • Evaluate primary cemented fixation through zonal radiographic analysis post-operatively

    minimum 1 year (304 to 668 days), minimum 2 year (669 to 1763 days)

  • +6 more secondary outcomes
