The summary describes a physical implant (tibial component) and does not mention any software, algorithms, or data processing that would indicate AI/ML.
Yes
The device is described as a "Continuum Knee System® Cobalt Chromium Alloy Tibial Component" intended for "severe degeneration, trauma, or pathology of the knee joint indicates cemented total knee arthroplasty." This indicates it is used to treat or alleviate a disease or injury, which aligns with the definition of a therapeutic device.
No
Explanation: The device is a knee implant intended for total knee arthroplasty, not for diagnosing conditions.
No
The device description explicitly states it is a "Cobalt Chromium Alloy Tibial Component," which is a physical hardware 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 describes a surgical implant for total knee arthroplasty, which is a procedure performed in vivo (within the body).
- Device Description: The device is a tibial component, a physical implant.
- Lack of IVD Characteristics: There is no mention of analyzing samples (blood, tissue, etc.) in vitro (outside the body) to diagnose a condition. The device itself is the treatment/replacement.
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device does not fit that description.
N/A
Intended Use / Indications for Use
The Continuum Knee System® Cobalt Chromium Alloy Tibial Component is intended for use where severe degeneration, trauma, or pathology of the knee joint indicates cemented total knee arthroplasty.

§ 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.

Re: K984291 Implex Continuum Knee System® Cobalt Chromium Alloy Tibial Component Regulatory Class: II Product Code: JWH Dated: November 25, 1998 Received: December 1, 1998
Dear Mr. Schalago:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). This decision is based on this device being equivalent only to similar devices labeled and intended to be fixed within bone with acrylic "bone cement." You may, therefore, market your device subject to the general controls provisions of the Act and the following limitations:
- This device may not be labeled or promoted for non-1. cemented use.
- All labeling for this device, including package label 2. and labeling included within the package, must prominently state that the device is intended for cemented use only.
-
- Any non-cemented fixation of this device is considered investigational and may only be investigated as a significant risk device in accordance with the investigational device exemption (IDE) regulation under 21 CFR, Part 812. All users of the device for non-

cemented fixation must receive approval from their respective institutional review boards (IRBs) and the Food and Drug Administration (FDA) to conduct the investigation.
The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practices, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Requlations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Requlation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal Laws or Requlations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification immediately. An FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4659. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to
premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be
