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 patellofemoral 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 indicated for cemented use only.
Device Description
The proposed device is part of the NexGen system of semiconstrained, nonlinked knee prostheses.
More Information

Not Found

No
The summary describes a knee prosthesis and does not mention any AI or ML components, image processing, or data sets typically associated with AI/ML device development.

Yes
The device is indicated for patients with severe knee pain and disability due to various conditions, aiming to alleviate symptoms and restore function in the knee joint. This aligns with the definition of a therapeutic device designed to treat or manage a disease or condition.

No
The device description clearly states it is a knee prosthesis, which is an implant for treatment, not a diagnostic tool. The "Intended Use" section also describes conditions that lead to its use as a treatment for severe knee pain and disability, not for diagnosis.

No

The device description explicitly states it is a "part of the NexGen system of semiconstrained, nonlinked knee prostheses," which are physical implants. The intended use also describes conditions requiring surgical intervention and implantation.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
  • Device Description and Intended Use: The provided text describes a knee prosthesis, which is an implantable device used to replace a damaged knee joint. Its intended use is to treat severe knee pain and disability by surgically replacing the joint.
  • Lack of Diagnostic Activity: The device itself does not perform any tests on bodily samples to diagnose a condition. It is a therapeutic device used to treat a pre-existing condition.

Therefore, based on the provided information, this device clearly falls outside the definition of an In Vitro Diagnostic.

§ 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.
