Intended Use
The Hybrid Knee Femoral Components are intended to be used for those patients whereby conditions exist that can not be solely addressed by a device that treats a single compartment (i.e. unicondylar or patellofemoral prosthesis) of the knee. Indications include: - post-traumatic arthritis; . - degenerative arthritis; and ● - failed osteotomies, hemiarthroplasties; and unicompartmental replacement . These indications will be used for the Hybrid Knee Femoral Components, whereby the medial condyle and patellofemoral regions have been affected by one or more of these conditions. The Hybrid Knee Femoral Components are single use only and are intended for implantation only with bone cement.
Device Description
The Smith & Nephew Hybrid Knee Femoral Components are designed for use with tibial components of the Genesis I Unicondylar Knee System and patellar components of the Genesis II Total Knee System. The components are used to replace the medial condyle and patellofemoral regions of a femoral knee joint.
More Information

I'm sorry, but the Predicate Device(s) K/DEN number is not found in the provided text.

Not Found

No
The summary describes a mechanical knee implant and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.

Yes
Explanation: The device is a knee implant intended to treat conditions like post-traumatic arthritis, degenerative arthritis, and failed previous surgeries, which are medical conditions, thereby providing therapeutic benefits to the patient.

No

The device description indicates it is a component for knee replacement, which is a therapeutic device, not a diagnostic one.

No

The device description clearly states it is a physical implant (femoral components) intended for surgical implantation, not software.

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

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Description: The description clearly states that the Hybrid Knee Femoral Components are implants used to replace parts of the knee joint. This is a surgical device, not a diagnostic test performed on a sample.
  • Intended Use: The intended use describes treating conditions like arthritis and failed previous surgeries by replacing parts of the knee, which is a therapeutic intervention, not a diagnostic one.

Therefore, the Hybrid Knee Femoral Components are 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.

Mechanical and Clinical Data

A review of the mechanical test data indicated that the Smith & Nephew Hybrid Knee Femoral Components are equivalent to devices currently used clinically and are capable of withstanding expected in vivo loading without failure.

Substantial Equivalence Information

The substantial equivalence of the Smith & Nephew Hybrid Knee Femoral Components is substantiated by its similarities in design features, overall indications, and material composition as existing components of the Genesis I Unicondylar Knee System and Genesis II Total Knee Systems distributed by Smith & Nephew, Inc., as well as other commercially available patellofemoral joint prostheses.
