The summary describes a traditional knee implant system and its components, materials, and non-clinical testing. There is no mention of AI, ML, image processing, or any software-driven analytical capabilities.
Yes
The A200 Knee System is intended for use in total knee arthroplasty to address painful and disabled knee joints, correct deformities, and revise unsuccessful prior procedures, aiming to alleviate symptoms and improve joint function.
No
The A200 Knee System is described as a total knee arthroplasty system, which is a prosthetic device for replacing a joint, not a device used to identify or diagnose a condition.
No
The device description clearly outlines multiple physical components made of various materials (Co-Cr-Mo alloy, Ti 6Al 4V alloy, UHMWPE) and includes instrumentation. This indicates it is a hardware-based medical device, not software-only.
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 total knee arthroplasty to address painful and disabled knee joints due to various conditions. This is a therapeutic intervention performed in vivo (within the body).
- Device Description: The device components are implants (femoral, tibial, patellar) and associated instrumentation for surgical implantation. These are physical devices used in surgery, not for testing samples in vitro (outside the body).
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, calibrators, controls, or any other elements typically associated with in vitro diagnostic testing.
Therefore, the A200 Knee System is a surgical implant device, 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.

Dear Dr. Thomas:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.
