Intended Use
The Revision Knee System Components are indicated for rheumatoid arthritis; post-traumatic arthritis; osteoarthritis; degenerative arthritis; and failed osteotomies, unicompartmental replacement; or total knee arthroplasties. The components are designed for use 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. The Revision Knee Components are for single use only and are intended for implantation with bone cement. These indications are the same as currently used for the Genesis II Constrained Knee System and Revision Knee System cleared via K962137 and K041106.
Device Description
The Smith & Nephew Revision Knee System contains femoral knee components, tibial components, angled and offset couplers, stem attachments and wedges. The designs of these devices are based upon existing components of the Genesis II Total Knee System and Revision System, previously cleared for market under K951987, K953274, K962137, and K041106.
More Information

No
The summary describes a mechanical knee implant system and makes no mention of AI or ML technology.

Yes
The device is a knee replacement system used to treat various arthritic conditions and failed prior surgeries, which directly addresses a medical condition to restore function.

No

The device is a knee implant system used for surgical replacement, not for diagnosing medical conditions.

No

The device description explicitly lists physical components like femoral knee components, tibial components, couplers, stem attachments, and wedges, indicating it is a hardware-based medical device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use describes the device as a system of components for surgical implantation in the knee to treat various arthritic conditions and failed previous surgeries. This is a therapeutic and surgical intervention, not a diagnostic test performed on samples taken from the body.
  • Device Description: The device description details physical components like femoral and tibial components, couplers, stems, and wedges, which are typical of orthopedic implants.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (like blood, urine, tissue, etc.) outside of the body to provide information for diagnosis, monitoring, or screening.

IVD devices are used to perform tests on samples taken from the human body to provide information about a person's health. This device is a surgical implant used to replace or augment a damaged joint.

§ 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.
