The summary describes a mechanical implant (tibial cone augments) and a finite element analysis study, with no mention of AI or ML technology.
Yes.
The device is an implant used in total knee arthroplasty to treat severe degeneration, trauma, or other pathology of the knee joint. This constitutes a therapeutic use to alleviate a pathological condition.
No
Explanation: The device is described as a "Tibial Cone Augment" used in total knee arthroplasty, indicating it is an implant for surgical intervention, not a tool for diagnosis.
No
The device description clearly states the device is manufactured from Trabecular Metal porous tantalum, which is a physical material, not software. The description details the physical characteristics and intended use as a physical implant in knee arthroplasty.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for use in total knee arthroplasty, which is a surgical procedure involving the replacement of a joint. This is a therapeutic intervention, not a diagnostic test performed in vitro (outside the body).
- Device Description: The description details a physical implant made of Trabecular Metal porous tantalum, designed to be surgically implanted in the knee joint. This is consistent with a medical device used for treatment, not a diagnostic reagent or instrument.
- Lack of IVD Indicators: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in biological samples
- Providing information for diagnosis, monitoring, or screening of diseases or conditions
- Reagents, calibrators, controls, or instruments used for in vitro testing.
The device described is a surgical implant used to augment the tibia during knee replacement surgery.

Intended Use / Indications for Use
Trabecular Metal Tibial 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 Tibial Cone Augments are for cemented use only. When used with the NexGen Complete Knee Solution - Legacy Constrained Condylar Knee System, the Trabecular Metal Tibial Cone Augments are for cementless or cemented use.

Device Description
The existing, commercially available NexGen® Trabecular Metal™ Tibial Cone Augments are manufactured wholly of Trabecular Metal porous tantalum, the same material that comprises numerous medical devices intended for use in orthopedic applications. The devices which are the subject of this 510(k), the modified NexGen Trabecular Metal Tibial Cone Augments are also manufactured of the same Trabecular Metal material, using the same methods as the predicate device. The existing, commercially available NexGen Trabecular Metal Tibial Cone Augments have tapered posterior, medial and lateral walls. The periphery of the inferior surface is smaller than that of the superior surface. A similar taper pattern is also present in the modified tibial cones.
Both the modified tibial cones augments and the existing, commercially available tibial cone augments are to be used in conjunction with Zimmer's NexGen® Complete Knee Systems- both the Legacy® Constrained Condylar Knee (LCCK) Stemmed Tibial Bases and the tibial component of Zimmer's Rotating Hinge Knee (RHK) System. Fixation of all of the cone augments to the tibial implant is accomplished by cementing the superior portion of the augment to the underside of the tibial baseplate. Apposition of the cone to bone inside the medullary canal is with or without cement when used with the LCCK tibial implant and with cement for the RHK tibial implant. With all of these tibial cone augments the LCCK tibial baseplate inferior surface must be cemented to the bone and the required stem extensions can either be cemented or press-fit.
The existing, commercially available augments come in four medium & large sizes, two height options and stepped augments. They can be used in conjunction with Zimmer's LCCK or RHK Knee Systems.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A comparative Finite Element Analysis (FEA) study was performed to determine whether the proposed design represented a worst case for the product line across different normal gait activities (walking and deep flexion). The results of testing and analyses conducted demonstrate that the proposed implants adequately meet the predetermined requirements established for its mechanical performance, supporting substantial equivalence to the predicate Trabecular Metal™ Tibial Cones.

§ 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.
