Intended Use
The Klassic® Knee System is intended for prosthetic replacement of the following: - Patient conditions of non-inflammatory degenerative joint disease (NIDJD): avascular necrosis and osteoarthritis - Patient conditions of inflammatory joint disease (IJD): rheumatoid arthritis - Patients with failed previous surgery where pain, deformity, or dysfunction persists - Correctable varus-valgus deformity and moderate flexion contracture - Revision of a previously failed knee arthroplasty - Patients who require a total knee replacement. The Klassic® Knee System is indicated for cemented use only, except for the Klassic Femur, Porous, and the Klassic Tibial Baseplate, Porous, which are indicated for cementless use.
Device Description
The Klassic® Knee System employs prostheses designed to help surgeons restore knee joint biomechanics intra-operatively. The purpose of this 510(k) is to add the posterior stabilizing Klassic® Knee Femur, PS-Post; Klassic Femoral Pegs; and the Klassic® Tibial Insert, PS-Post with Standard Poly; and the Klassic® Tibial Insert, PS-Post with E-Link® Poly; to the Klassic Knee System. The subject femoral and tibial components are available in various sizes and thicknesses to match patient anatomy.
More Information

Not Found

No
The summary describes a traditional knee implant system and its components. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in medical devices. The performance studies focus on mechanical and material properties.

Yes
The device is a prosthetic replacement for the knee joint, intended to treat conditions like degenerative joint disease and inflammatory joint disease, which are therapeutic interventions.

No

Explanation: This device, the Klassic® Knee System, is a prosthetic replacement for the knee joint. Its intended use is to replace affected parts of the knee in patients with various joint diseases or failed previous surgeries. It is an implantable device used for surgical treatment, not for diagnosing conditions.

No

The device description clearly states it is a "Klassic® Knee System" which includes femoral and tibial components, indicating physical implants, not software. The performance studies also describe engineering analysis and testing of physical components like pegs, inserts, and the femur/tibial components.

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 prosthetic replacement for the knee joint to address various conditions like osteoarthritis, rheumatoid arthritis, and failed previous surgeries. This is a surgical implant, not a diagnostic test performed on samples taken from the body.
  • Device Description: The device description details components of a knee replacement system (femoral and tibial components, inserts, pegs). These are physical implants designed to be surgically placed within the body.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific markers, or providing diagnostic information about a patient's condition based on in vitro testing.

Therefore, the Klassic® Knee System is a surgical implant, not an In Vitro Diagnostic device.

§ 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 Chris Weaber:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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
