No
The summary describes a mechanical knee implant system and explicitly states no new components are being introduced, focusing on adding gender-related claims to existing cleared devices. There is no mention of AI/ML terms, image processing, or data sets typically associated with AI/ML device descriptions.
No.
The device is a knee implant, which is a replacement for a joint. While it aims to improve a patient's quality of life by alleviating pain and restoring function, it is generally considered a medical device (prosthesis) rather than a therapeutic device in the sense of delivering therapy. Therapeutic devices typically administer treatment, such as radiation therapy, electrical stimulation, or drug delivery.
No
The document describes total knee components used for treatment of arthritis and ligament issues, which are therapeutic devices, not diagnostic devices.
No
The device description explicitly states it is adding gender-related claims to existing total knee systems, which are physical implants. It does not describe a software-only device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes the device as total knee components for surgical implantation to treat various forms of arthritis and failed previous surgeries. This is a therapeutic and reconstructive purpose, not a diagnostic one.
- Device Description: The description confirms the device is a total knee system, which is a physical implant.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
Therefore, this device falls under the category of a surgical implant or prosthetic device, not an In Vitro Diagnostic.

Intended Use / Indications for Use
Total knee components are indicated for rheumatoid arthritis; post-traumatic arthritis, or degenerative arthritis in older patients whose age, weight, and activity level are compatible with an adequate long-term result; failed osteotomies, unicompartmental replacement, or total knee replacement. Posterior stabilized knee systems are designed for use in patients in primary and revision surgery, where the anterior and posterior cruciate ligaments are absent or incompetent and the collateral ligaments remain intact. Constrained knee systems are designed for use in patients in primary and revision surgery, where the posterior cruciate ligament and one or both of the collateral ligaments (i.e. medial collateral and/or lateral collateral ligament) are absent or incompetent. Total knee components are single use devices and may be used in cemented or uncemented applications.

§ 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.

Device Description
The Smith & Nephew, Inc. Gender Knee Systems are the existing Smith & Nephew, Inc. Genesis II, Legion, and Journey BCS Knee Systems. This premarket notification seeks only to add gender-related claims for these existing total knee systems previously cleared by FDA marketed by Smith & Nephew.

Total knee components are indicated for rheumatoid arthritis; post-traumatic arthritis, or degenerative arthritis in older patients whose age, weight, and activity level are compatible with an adequate long-term result; failed osteotomies, unicompartmental replacement, or total knee replacement. Posterior stabilized knee systems are designed for use in patients in primary and revision surgery, where the anterior and posterior cruciate ligaments are absent or incompetent and the collateral ligaments remain intact.

Substantial Equivalence Information
The Smith & Nephew, Inc. Gender Knee Systems are the existing Smith & Nephew, Inc. Genesis II, Legion, and Journey BCS Knee Systems previously cleared for market by FDA through various premarket notifications. The gender-specific claims being made about these devices are similar to those of the Zimmer NexGen Knee Gender Solutions Female (GSF) Femoral Components (K060370), the Zimmer Gender Solutions Natural-Knee Flex System (K070214), and the Stryker Triathlon Total Knee System (K053514).

Dear Mr. Sells:
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set

forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
