No
The document describes a mechanical implant (patella component for knee replacement) and its material properties and testing. There is no mention of software, algorithms, or any features that would suggest the use of AI or ML.
Yes
The device, a metal-backed patella component for total knee arthroplasty, is used to treat painful and disabling joint diseases, restore function, and address various knee conditions, which are therapeutic interventions.
No
This device is a component of a total knee arthroplasty system, indicated for surgical implantation to replace or repair knee joints. It is a therapeutic device, not a diagnostic one.
No
The device description clearly states it is a physical implant (metal-backed patella) made from UHMWPE and titanium, intended for surgical implantation. It is not software.
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: The device described is a Total Knee Arthroplasty (TKR) system, specifically focusing on a metal-backed patella component. This is an implantable medical device used in surgery to replace a damaged knee joint.
- Intended Use: The intended use is for the surgical treatment of painful and disabling knee joint diseases and injuries. This is a surgical procedure, not a diagnostic test performed on a sample outside the body.
- Lack of IVD Indicators: The document does not mention any of the typical characteristics of an IVD, such as:
- Analysis of biological samples.
- Detection of biomarkers, pathogens, or genetic material.
- Use in a laboratory setting for diagnostic purposes.
The information clearly describes a surgical implant and its intended use in replacing a knee joint, which falls under the category of a surgical device, not an in vitro diagnostic device.

§ 888.3565 Knee joint patellofemorotibial metal/polymer porous-coated uncemented prosthesis.
(a)
Identification. A knee joint patellofemorotibial metal/polymer porous-coated uncemented 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 is designed to achieve biological fixation to bone without the use of bone cement. This identification includes fixed-bearing knee prostheses where the ultra high molecular weight polyethylene tibial bearing is rigidly secured to the metal tibial base plate.(b)
Classification. Class II (special controls). The special control is FDA's guidance: “Class II Special Controls Guidance Document: Knee Joint Patellofemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses; Guidance for Industry and FDA.” See § 888.1 for the availability of this guidance.
