ATTUNE® Revision- Complex Primary in Total Knee Arthroplasty Population

Multi-Center Clinical Evaluation of the ATTUNE Revision System in Complex Primary Total Knee Arthroplasty

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.

Study Overview

• Status: Recruiting
• Conditions: Primary Knee Arthroplasty
• Intervention / Treatment: Device: ATTUNE Revision Knee System in Total Knee Arthroplasty

Detailed 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.

Intervention / Treatment

Other: ATTUNE Revision knee system; The ATTUNE Revision knees system is complementary to the ATTUNE primary knee portfolio and includes both rotating platform (RP) and fixed bearing (FB) configurations. The system includes a full compliment of implants designed to address the challenges faced in complex primary knee surgeries. These implants include Stemmable tibial and femoral components, augments, sleeves and offsets

Device: ATTUNE Revision Knee System in Total Knee Arthroplasty; Implants from the ATTUNE Revision Knee System will be used to treat subjects whose surgeons have determined their anatomy is such that the use of revision components are required to perform primary total knee arthroplasty; Other Names: complex primary knee arthroplasty
