No
The summary describes a mechanical implant (femoral cone augments) and its material properties and mechanical testing. There is no mention of software, algorithms, image processing, or any terms related to AI or ML.
Yes
The device is intended for use in total knee arthroplasty to address severe degeneration, trauma, or other pathology of the knee joint, which falls under the definition of a therapeutic intervention.
No
Explanation: This device is a surgical implant (femoral cone augment) used in total knee arthroplasty, not a tool for diagnosing medical conditions.
No
The device is described as being manufactured wholly of Trabecular Metal™, porous tantalum, and undergoes mechanical testing and finite element analysis, indicating it is a physical implant and 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 and Intended Use: The description clearly states that the Trabecular Metal Femoral Cone Augments are implants intended for use in total knee arthroplasty (knee replacement surgery). They are physical components used within the body to augment the femoral bone.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information based on laboratory testing. The device is a surgical implant.
Therefore, this device falls under the category of a surgical implant or orthopedic device, not an in vitro diagnostic.
N/A
Intended Use / Indications for Use
Trabecular Metal Femoral Cone Augments are intended for use where severe degeneration, trauma, or other pathology of the knee joint indicates total knee arthroplasty. When used with the NexGen Complete Knee Solution - Rotating Hinge Knee (RHK) System, the Trabecular Metal Femoral Cone Augments are for cemented use only. When used with the NexGen Complete Knee Solution - Legacy Constrained Condylar Knee System, the Trabecular Metal Femoral Cone Augments are for cementless or cemented use.

Device Description
The NexGen® Trabecular Metal™ Femoral Cone Augments are manufactured wholly of Trabecular Metal™, porous tantalum. The existing, commercially available NexGen® Trabecular Metal™ Femoral Cone Augments have a tapered elliptical cross-section. The periphery of the distal end is larger than that of the proximal end. The cone is not fully enclosed at its top most proximal section (giving the impression of U-Shape through slot). A similar pattern is also present in the modified femoral cones, with the exception that these cones are fully enclosed at its top most proximal section.
Both the modified femoral cones augments and the existing, commercially available femoral cone augments are to be used in conjunction with Zimmer's NexGen® Complete Knee Systems -both the Legacy® Constrained Condylar Knee (LCCK) Stemmed Femoral Implant and the femoral component of Zimmer's Rotating Hinge Knee (RHK) System. When used with the RHK System, the Trabecular Metal™ Femoral Cone Augments are for cemented use only. Fixation of all of the cone augments to the femoral implant is accomplished by cementing the internal portion of the augment to the superior side (non-articulating side) of the femoral component. Apposition of the cone to bone inside the medullary canal is with or without cement when used with the LCCK femoral implant and with cement for the RHK femoral implant.
The existing, commercially available augments come in three sizes; small, medium and large and three height options. The proposed additional femoral cones will come in the same three sizes: small, medium and large and two height options.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance testing of Trabecular Metal™ material is included in a master file, on file at the FDA, which includes static compression, static shear, axial compression fatigue and rotational beam fatigue. Young's modulus of elasticity of Trabecular Metal has been measured in tension and compression. The results of testing and analysis define the properties of Trabecular Metal™, porous tantalum.
Mechanical testing was performed on Trabecular Metal predicate devices which include fatigue testing, wear testing, and assembly torque testing. The results of testing and analyses conducted indicate that predicates of the Trabecular Metal™ Femoral Cone Augments should maintain assembly integrity when assembled using the surgical technique instructions.
A comparative Finite Element Analysis (FEA) study was performed to evaluate the strength of the proposed femoral cone designs across different normal gait activities (walking, stair ascent/decent and deep flexion). The results of testing and analyses conducted demonstrate that the proposed implant adequately meets the predetermined requirements established for its mechanical performance, supporting substantial equivalence to the predicate.

§ 888.3565 Knee joint patellofemorotibial metal/polymer porous-coated uncemented prosthesis.
(a)
Identification. A knee joint patellofemorotibial metal/polymer porous-coated uncemented 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 is designed to achieve biological fixation to bone without the use of bone cement. This identification includes fixed-bearing knee prostheses where the ultra high molecular weight polyethylene tibial bearing is rigidly secured to the metal tibial base plate.(b)
Classification. Class II (special controls). The special control is FDA's guidance: “Class II Special Controls Guidance Document: Knee Joint Patellofemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses; Guidance for Industry and FDA.” See § 888.1 for the availability of this guidance.

DEVICE TECHNOLOGICAL CHARACTERISTICS AND COMPARISON TO PREDICATE DEVICES
The NexGen® Trabecular Metal™ Femoral Cone Augments were shown to be substantially equivalent to legally marketed predicate devices. The predicate devices are Zimmer's Trabecular Metal™ Femoral Cone Augments (K040630, K051756, K053340), Zimmer's NexGen® Trabecular Metal™ Tibial Cone Augments (K031962, K053340), Zimmer's NexGen® Complete Knee Solution - Trabecular Metal™ Augments (K024161, K040487), Zimmer's (formerly Implex) Continuum Knee System Trabecular Metal™ (formerly Hedrocel®) Tibial Spacers (K982302), and Zimmer's (formerly Implex) Continuum Knee System Trabecular Metal™ (formerly Hedrocel®) Revision Femoral Spacers (K0980781).
The NexGen® Trabecular Metal™ Femoral Cone Augments have the same material as previously cleared predicate devices. The intended use and indications for use of the subject devices are identical to that of the predicate. This submission is for an extension of the product line; sizes, cross sectional dimensions, design features and overall geometry of the device in the current submission are similar to the predicate device.
There are no significant differences between the proposed NexGen® Trabecular Metal™ Femoral Cone Augments and the predicate currently being marketed that would adversely affect the use of the product. Any differences in technological characteristics do not raise new issues of safety and efficacy.
