AI/ML (Artificial Intelligence / Machine Learning)

No
The document explicitly states that the only changes to the device are updates to labeling to include MR Conditional language and symbols. The device description focuses on the materials and design of passive implants, and the testing described is related to MR compatibility, not AI/ML performance. There is no mention of AI, ML, or related concepts in the document.

Therapeutic

Yes
The device, referred to as MicroPort Total Knee Systems, is a knee arthroplasty implant that is indicated for use in treating various degenerative joint diseases and functional deformities. Its purpose is to correct or alleviate these conditions, which directly relates to therapy.

Diagnostic

No

Explanation: The device described is a knee replacement system (implant components used in knee arthroplasty), which is a therapeutic device, not a diagnostic one. Its intended use is to treat various knee conditions and correct deformities, not to diagnose them.

SaMD (Software as a Medical Device)

No

The device description explicitly states that the subject devices are implant components used in knee arthroplasty, which are physical hardware components (metal and UHMWPE). The submission is for labeling updates and testing related to the MR compatibility of these physical implants.

IVD (In Vitro Diagnostic)

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

Intended Use: The intended use clearly states that the MicroPort Total Knee Systems are indicated for use in knee arthroplasty in skeletally mature patients with various knee conditions. This is a surgical implant used in vivo (within the body) to replace a joint.
Device Description: The device description details implant components like femoral components, tibial inserts, tibial bases, and patellae, all designed for surgical implantation.
IVD Definition: In Vitro Diagnostics (IVDs) are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to provide information about a person's health. This device does not perform such tests.

The information about MR compatibility and testing relates to the safety and performance of the implant when the patient undergoes an MRI, which is a common imaging modality used in conjunction with such implants. This does not change the fundamental nature of the device as a surgical implant rather than an IVD.

Summary of Performance Studies

Non clinical Testing was conducted to establish the conditional safety and compatibility of the passive implants in a magnetic resonance (MR) environment according to the recommendations provided in the guidance document "Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment" issued on December 11, 2014. Testing was also conducted according to the following standards:

ASTM F2052-14. "Standard test method for measurement of magnetically induced displacement force on passive implants in the magnetic resonance environment";

ASTM F2119-7 "Standard Test Method for Evaluation of MR Image Artifacts from Passive Implants":

ASTM F2503-13 "Standard Practice for Marking Medical Devices and Other Items for Safety in the Magnetic Resonance Environment";

ASTM F2182-11a "Standard Test Method for Measurement of Radio Frequency Induced Heating near Passive Implants During Magnetic Resonance Imaging"

The tests determined the effects of the MRI on the implants, and the effects of the implants on the image quality. The tests evaluated the worst case components and constructs for RF Heating, field interactions, and image artifacts. The testing concluded that there are no safety issues related to magnetic field interactions under specific conditions identified in the labeling.

Regulation Number and Section

§ 888.3530 Knee joint femorotibial metal/polymer semi-constrained cemented prosthesis.

(a)
Identification. A knee joint femorotibial metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace part of 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 consist of a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.
