Prospective, Multiconfiguration Study to Assess Functional Performance of Primary Total Knee Arthroplasty System

Completed

Conditions studied: Osteoarthritis

In brief

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).
