The summary describes a mechanical implant (metal-backed patella) and its intended use in total knee arthroplasty. There is no mention of AI, ML, image processing, or any software-based functionality that would suggest the use of these technologies.
Yes
The device is described as a patellar resurfacing component and a component of a total knee arthroplasty system, both of which are therapeutic interventions aimed at alleviating pain and restoring function in the knee joint.
No
The device description indicates it is a medical implant (patellar resurfacing to alleviate pain, instability, and restriction of motion), not a device used for diagnosis.
No
The device description clearly states it is a "metal-backed patella" with a "porous coated metal back" and "polyethylene anterior surface," indicating it is a physical implant, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical implant for replacing parts of the knee joint to alleviate pain and restore function. This is a therapeutic device, not a diagnostic one.
- Device Description: The description details a physical implant made of metal and polyethylene, designed for surgical implantation. This is consistent with a medical device used in surgery, not a diagnostic test performed on biological samples.
- 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 laboratory analysis.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device is a physical implant used to treat a condition, not to diagnose it.

§ 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.
