No
The document describes a mechanical knee implant component and does not mention any software, algorithms, or AI/ML capabilities.
Yes
This device is a total knee replacement component, which is used to treat medical conditions like arthritis, thus serving a therapeutic purpose.
No
The provided text describes a "Profix Flex Cruciate Retaining (CR) articular insert" which is a component of a total knee system. Its purpose is to replace knee components in patients with conditions like arthritis, not to diagnose a medical condition.
No
The device description explicitly states it is a UHMWPE tibial component, which is a physical hardware component, not software.
No, 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: The provided text describes a total knee component, specifically an articular insert made of UHMWPE. This is a surgical implant designed to be placed inside the body to replace a damaged knee joint.
- Intended Use: The intended use clearly states it's for treating conditions like rheumatoid arthritis and post-traumatic arthritis by replacing parts of the knee joint. This is a therapeutic intervention, not a diagnostic test.
The information provided focuses on the mechanical properties and surgical application of the device, which is consistent with a medical implant, not an IVD.

§ 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.
