No
The device description and performance studies focus on the material properties and mechanical testing of knee implant components, with no mention of AI or ML.
Yes.
The device is a medical implant (patellar component for knee replacement) used to treat conditions like arthritis and patellar dislocation, which falls under the definition of a therapeutic device.
No
The device is a knee implant component, specifically a resurfacing patellar component, designed for surgical replacement in total knee and patello-femoral knee systems. Its function is to be implanted, not to diagnose.
No
The device description clearly states that the device is a physical component (resurfacing patellar components) made from highly cross-linked polyethylene (XLPE) material, intended for surgical implantation. It is a hardware device, not software.
Based on the provided text, 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 description clearly states that the device is a "resurfacing patellar component manufactured from highly cross linked polyethylene (XLPE) material." This is a physical implant intended for surgical use within the body.
- Intended Use/Indications for Use: The indications describe conditions requiring knee replacement surgery, such as arthritis and failed previous surgeries. These are surgical procedures, not diagnostic tests performed on samples.
- Lack of IVD Language: The document does not mention any terms related to laboratory testing, samples, analysis of biological materials, or diagnostic purposes.
Therefore, the Genesis II XLPE Resurfacing Patellar Components are a surgical implant, not an in vitro diagnostic device.

§ 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.
