The summary describes a traditional mechanical knee replacement system and does not mention any AI or ML components or functionalities.
Yes.
The device is a knee replacement prosthesis designed to treat severely painful and/or disabled knee joints.
No
This device is a total knee replacement prosthesis, which is an implant used for treatment through surgical replacement, not for diagnosing conditions.
No
The device description explicitly lists various physical components made of materials like Co-Cr-Mo alloy, UHMWPE, and Ti-6Al-4V ELI alloy, indicating it is a hardware-based medical device (a total knee replacement prosthesis).
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description and Intended Use: The description clearly states that the ATTUNE Revision Knee System is a total knee replacement prosthesis consisting of various components designed for total knee arthroplasty. This is a surgical procedure to replace a damaged joint.
- Lack of Diagnostic Activity: There is no mention of the device analyzing biological samples or providing diagnostic information about a patient's health status. Its purpose is to physically replace a damaged joint.
Therefore, the ATTUNE Revision Knee System is a medical device used in a surgical procedure, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
Candidates for total knee replacement include patients with:
- A severely painful and/or severely disabled joint resulting from osteoarthritis, post-● traumatic arthritis, or rheumatoid arthritis
- Moderate valgus, varus, or flexion deformities
- Avascular necrosis of the femoral condyle
- A previous unsuccessful knee replacement, osteotomy, or other knee procedure ●
ATTUNE Revision Knee System implants are designed for use in total knee arthroplasty for patients with:
- Absence or loss of both cruciate ligaments ●
- Moderate varus-valgus or flexion instability that requires a bearing surface with increased ● constraint in the clinical judgment of the surgeon
- Bone loss that requires supplemental fixation in the clinical judgment of the surgeon
The porous-coated metaphyseal sleeves are intended for either cemented or cementless applications.
Any non porous-coated components are intended for cemented use only.

Device Description
The ATTUNE Revision Knee System is composed of various components:
ATTUNE REVISION CRS FEMORAL COMPONENTS: Manufactured from cast Co-Cr-Mo alloy (ASTM F75), these components have an asymmetric trochlear groove and are available in sizes 1 to 10 for both right and left knees. They include a fixed boss for attachment of ATTUNE Revision Femoral Sleeves or ATTUNE Revision Stems, augment holes for ATTUNE Revision Femoral Augments, recessed cement pockets, and a textured fixation surface. A removable UHMWPE (ASTM F648) plug is pre-assembled in the stem boss.
ATTUNE REVISION CRS FIXED BEARING INSERTS: These UHMWPE Antioxidant (AOX) Tibial Inserts are manufactured from raw materials conforming to ASTM F648. They articulate with the ATTUNE Revision CRS Femoral Components and are available in sizes 1 to 10, with thicknesses ranging from 6 to 26mm.
ATTUNE REVISION FIXED BEARING TIBIAL BASES: Manufactured from cast Co-Cr-Mo alloy (ASTM F75) with a Ti-6Al-4V removable end cap, these Tibial Bases are available in sizes 1 to 10. They feature augment holes for ATTUNE Revision Tibial Augments, a textured fixation surface, a stem and keel for stability, and recessed cement pockets. They utilize a central, universal locking mechanism and include a pre-assembled Base Protector to minimize marring during impaction.
ATTUNE REVISION STEMS: Made from Ti-6Al-4V ELI alloy (ASTM F136), these optional components provide additional fixation. They are compatible with ATTUNE Revision CRS Femoral, ATTUNE Revision Fixed Bearing Tibial Base, ATTUNE Revision Offset Adaptor, and ATTUNE Revision Femoral Sleeve components, and utilize a threaded junction. Press-fit Stems are cross-slotted with a cone-shaped distal tip for insertion. Cemented Stems have cylindrical or tapered body geometry depending on length, recessed cement pockets, and a blasted and fluted fixation surface.
ATTUNE REVISION FEMORAL SLEEVES: Manufactured from Ti-6Al-4V alloy (ASTM F620 or ASTM F136), these optional components improve femoral prosthesis fit where metaphyseal bone is absent or of poor quality. They have a symmetric taper geometry with steps for initial fixation and bone loading. Six sizes (30-55mm) are available in non-porous cemented (30mm only), partially porous coated, or fully porous coated options. They use a locking taper to attach to the ATTUNE Revision CRS Femoral Component and a threaded junction with ATTUNE Revision Stem components. A removable UHMWPE (ASTM F-648) plug is pre-assembled.
ATTUNE REVISION FEMORAL AUGMENTS: Designed to build up distal and/or posterior interior surfaces for bony insufficiency and gap balancing. Manufactured from cast Co-Cr-Mo (ASTM F75), available in sizes 1 to 10 with varying thicknesses, they attach to the ATTUNE Revision CRS Femoral Component.
ATTUNE REVISION TIBIAL AUGMENTS: Manufactured from wrought Co-Cr-Mo alloy (ASTM F1537), cast Co-Cr-Mo alloy (ASTM F75), or forged Co-Cr-Mo alloy (ASTM F799). Available in sizes 1 to 10 and thicknesses of 5, 10, and 15mm, compatible with ATTUNE Revision Fixed Bearing Tibial Bases.

- Patellofemoral Contact Area and Contact Pressure Testing
- A-P Shear Spine Fatigue Testing
- Component Interlock Strength Testing: Offset Adaptor to Stem and Stem and Tibial Base
- Rollback Layout for Design Verification
- Component Interlock Strength Testing: Femoral Sleeve to Femoral Component
- Rotation Layout for Design Verification
- Component Interlock Strength Testing: Stem to Tibial Base
- Tibiofemoral Constraint Testing
- Component Interlock Strength Testing: Stem to Femoral Sleeve
- Medialized Dome Lateral Stability Testing

Indications for Use: Candidates for total knee replacement include patients with:
- A severely painful and/or severely disabled joint resulting from osteoarthritis, post-traumatic arthritis, or rheumatoid arthritis
- Moderate valgus, varus, or flexion deformities
- Avascular necrosis of the femoral condyle
- 0 A previous unsuccessful knee replacement, osteotomy, or other knee procedure
ATTUNE Revision Knee System implants are designed for use in total knee arthroplasty for patients with:
- Absence or loss of both cruciate ligaments ●
- Moderate varus-valgus or flexion instability that requires a bearing surface with increased constraint in the clinical judgment of the surgeon
- Bone loss that requires supplemental fixation in the clinical ● judgment of the surgeon

Summary of Technologies/ Substantial Equivalence:
The ATTUNE Revision Knee System has the same indications, manufacturing methods, and sterilization methods as previously cleared DePuy total knee replacement systems. The design, materials, and packaging are similar to those of the predicate devices.
Non-Clinical Testing:
The table below lists the functional testing that was conducted in compliance with FDA Guidance, Class II Special Controls Guidance Knee Joint Patellofemorotibial Caand F Femorotibial Document: Metal/Polymer Porous-Coated Uncemented Prostheses: Guidance for Industry and FDA, to verify that the implant performance is substantially equivalent to predicate devices for anticipated in-vivo loading via various constraint, contact, wear, and fatigue tests. The results demonstrated that the subject devices are substantially equivalent to the legally marketed predicate devices.
The proposed devices also meet the requirement of bacterial endotoxin testing as specified in ANSI AAMI ST-72:2011.
