The summary describes a mechanical knee implant and its components, with no mention of AI or ML in its design, function, or testing.
Yes
The device is a total knee replacement system intended for patients with severe knee joint pain and/or disability, directly addressing a health condition.
No
This device is described as a total knee replacement system, which is a therapeutic device (an implant), not a diagnostic one. Its purpose is to treat conditions like osteoarthritis by replacing a damaged joint, not to identify or diagnose them.
No
The device description clearly details physical components made of materials like ultra high molecular weight polyethylene and mentions fixation surfaces and pegs, indicating it is a hardware medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is clearly stated as a "total knee replacement system" for treating conditions like osteoarthritis, posttraumatic arthritis, rheumatoid arthritis, or a failed previous implant. This is a surgical implant, not a diagnostic test performed on samples from the body.
- Device Description: The description details the physical components of the knee implant (patellae, materials, design features). This aligns with a medical device intended for implantation, not a diagnostic tool.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific markers, or providing diagnostic information about a patient's condition based on in vitro analysis.
In summary, the DePuy Attune™ Total Knee System is a surgical implant used to replace a damaged knee joint, which falls under the category of a medical device, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
The DePuy Attune™ Total Knee System is intended for cemented use as a total knee replacement system. Candidates for total knee replacement include patients with a severely painful and/ or severely disabled joint resulting from osteoarthritis, posttraumatic arthritis, rheumatoid arthritis, or a failed previous implant.
Total knee replacement is intended to provide increased patient mobility and reduced pain by replacing the damaged knee joint articulation in patients where there is evidence of sufficient sound bone to seat and support the components.
The Attune CR Knee System is intended to accommodate knee flexion to 150 degrees in those patients able to attain a high degree of knee flexion.

Device Description
The Attune medialized dome and medialized anatomic patellae are available in sizes 29, 32, 35, 38, and 41mm. The fixation surface incorporates 3 pegs to provide stability and recessed cement pockets for enhanced cement fixation. The patella components are manufactured from AOX ultra high molecular weight polyethylene conforming to ASTM F648. The articular surface is offset medially proportional to the size of the component.

Summary of Performance Studies
Non-Clinical Testing: Functional testing was conducted in compliance with FDA guidance, Class II Special Controls Guidance Document: Knee Joint Patellofemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses: Guidance for Industry and FDA, to verify that the implant performance would be substantially equivalent to predicate devices for anticipated in vivo loading via constraint and contact tests.
Clinical Testing: None provided as it was not necessary to determine substantial equivalence between the Attune Knee System's medialized dome and medialized anatomic patellae and the predicate devices.

§ 888.3560 Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.
