Summary

Five-year, Prospective, multi-center, non-randomized, non-controlled study of the ATTUNE® Revision total knee prostheses, utilizing the fixed bearing (FB) and rotating platform (RP) tibial component with the posterior stabilizing (PS) femoral component in complex primary total knee arthroplasty.

Description

Within primary TKA, there are factors that lead to more complex procedures that include patients with high BMIs, advanced preoperative deformities and ligamentous laxity. Such cases may require the surgeon to treat using ancillary components, such as stems and/or augments and/or additional constraint.

This post-market study will evaluate the short/medium term clinical performance and medium term survivorship of the ATTUNE Revision system system, which includes instrumentation, in complex primary TKA. The study is designed as a worldwide non-comparative, multi-center study with each site initially having a cohort of approximately 20 Subjects to recruit. The study will enroll approximately 200 fixed bearing and approximately 200 rotating platform configurations.

The 2-year KOOS-ADL (activities of daily living) was selected as the primary endpoint because it will evaluate the post-operative period during which outcomes typically plateau and will therefore provide a good indication of longer term outcomes

Male and female Subjects, age 22-80 years, inclusive, who require a primary knee arthroplasty in a joint that, due to deformity, instability, bone loss etc., necessitates the use of implants found within the ATTUNE Revision knee system and are suitable candidates for TKA using the ATTUNE® Revision system are eligible for enrollment in this study.

Subject is currently involved in any personal injury litigation, medical-legal or worker's compensation claims
Subject, in the opinion of the Investigator, is a drug or alcohol abuser (in the last 5 years) or has a psychological disorder that could affect his/her ability to complete patient reported questionnaires or be compliant with follow-up requirements
Subject was diagnosed and is taking prescription medications to treat a muscular disorder that limits mobility due to severe stiffness and pain such as fibromyalgia or polymyalgia
Subject has a significant neurological or musculoskeletal disorder(s) or disease that may adversely affect gait or weight bearing activities (e.g., muscular dystrophy, multiple sclerosis, Charcot disease)
Subject has a medical condition with less than five (5) years life expectancy as determined by the Investigator
