Intended Use
This device is indicated for patients with severe knee pain and disability due to: - Rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis. - Collagen disorders, and/or avascular necrosis of the femoral condyle. - Post-traumatic loss of joint configuration, particularly when there is ratellofemoral erosion, dysfunction or prior patellectomy - Moderate valgus, varus, or flexion deformities. - The salvage of previously failed surgical attempts or for a knee in which satisfactory stability in flexion cannot be obtained at the time of surgery. This device is intended for cemented use only.
Device Description
The NexGen MIS Modular Tibial Plates and Keels are part of the NexGen system of semiconstrained, nonlinked condylar knee prostheses.
More Information

No
The summary describes a mechanical knee prosthesis and does not mention any software, algorithms, or AI/ML capabilities.

Yes
The device is a knee prosthesis indicated for patients with severe knee pain and disability due to various conditions, aiming to alleviate symptoms and restore function.

No
This is a knee prosthesis, which is an implant used to replace a damaged joint, not a device used to diagnose a medical condition.

No

The device description explicitly states "The NexGen MIS Modular Tibial Plates and Keels are part of the NexGen system of semiconstrained, nonlinked condylar knee prostheses," indicating it is a physical implant, not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a device used in vivo (within the body) for surgical implantation to treat severe knee pain and disability. IVDs are used in vitro (outside the body) to examine specimens like blood, urine, or tissue to diagnose or monitor conditions.
  • Device Description: The description refers to "Tibial Plates and Keels" which are components of a knee prosthesis, designed to be implanted into the knee joint.
  • Anatomical Site: The anatomical site is the "Knee," which is an internal body part.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples, using reagents, or providing diagnostic information based on laboratory tests.

This device is a surgical implant, specifically a knee prosthesis component.

Intended Use / Indications for Use

This device is indicated for patients with severe knee pain and disability due to:

  • Rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis.
  • Collagen disorders, and/or avascular necrosis of the femoral condyle.
  • Post-traumatic loss of joint configuration, particularly when there is ratellofemoral erosion, dysfunction or prior patellectomy
  • Moderate valgus, varus, or flexion deformities.
  • The salvage of previously failed surgical attempts or for a knee in which satisfactory stability in flexion cannot be obtained at the time of surgery.

This device is intended for cemented use only.

§ 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 Mr. Hipsher:

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 (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
