The description focuses on the material, design, and intended use of a physical implant for knee reconstruction, with no mention of software, algorithms, or data processing.
Yes
The device is indicated for reconstruction of bony defects in the knee due to degeneration, trauma, or other pathologies, as well as revision or salvage of failed knee procedures, which are therapeutic interventions.
No
The device is a knee implant used for reconstruction of bony defects, not for diagnosing conditions.
No
The device description clearly states the device is manufactured from "Trabecular Metal" and is a physical implant (tibial cone augments) used in knee reconstruction.
Based on the provided text, 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, or tissue) to provide information about a person's health.
- Device Description: The description clearly states that the NexGen Trabecular Metal Tibial Cone Augments are implants designed to be used in surgical procedures to reconstruct bony defects in the knee. They are physically implanted into the body.
- Intended Use: The intended use is for surgical reconstruction of the knee joint due to various pathologies or failed procedures. This is a surgical intervention, not a diagnostic test performed on a sample outside the body.
Therefore, this device falls under the category of a surgical implant or orthopedic device, not an In Vitro Diagnostic.

Intended Use / Indications for Use
The NexGen Trabecular Metal Tibial Cone Augments are indicated for use in the reconstruction of bony defects in knee reconstruction due to severe degeneration, trauma, or other pathology of the knee joint, and in the revision or salvage of failed, previously reconstructed knee procedures and implants. The Trabecular Metal Tibial Cone Augments are for cemented use only in the USA, and for cementless or cemented use outside the USA.

Device Description
The NexGen Trabecular Metal Tibial Cone Augments are designed to be used in conjunction with Zimmer Inc.'s Legacy@ Stemmed Tibial Bases (LCCK) and Rotating Hinge Knee (RHK) tibial components. The subject devices are used to address proximal tibial cavitary defects encountered when implanting either of these two systems. The augments are manufactured from Trabecular Metal and have tapered posterior, medial and smaller lateral walls. The periphery of the inferior surface is smaller than that of the superior surface. The augments are hollow such that they are to be filled with bone cement, and allow for placement of the stem and/or keel of the associated tibial base plate. Fixation of the augment to the tibial baseplate is accomplished by using bone cement. The inferior surface of the LCCK and RHK tibial baseplates must be cemented to bone.
The Trabecular Metal Tibial Cone Augments are for cemented use along the bone in the USA, and for cementless or cemented use along the bone outside the USA.

§ 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)
