More Information

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
The device is described as a total knee replacement system intended for patients with severely disabled joints resulting from various arthritic conditions or a failed previous implant, indicating its purpose is to treat or alleviate a medical condition.

No

The device is a total knee replacement system, which is a prosthetic implant, not a diagnostic tool. Its purpose is to replace a damaged knee joint, not to identify or assess a medical condition.

No

The device description explicitly states it is a polyethylene tibial insert and patella component, which are physical hardware components of a knee replacement system.

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

Here's why:

  • Intended Use: The intended use is for a total knee replacement system, which is an implantable medical device used in surgery.
  • Device Description: The device is described as polyethylene tibial inserts and a patella component, which are physical components implanted into the body.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or treatment.

IVD devices are used outside the body to analyze samples, while this device is implanted inside the body to replace a joint.

Summary of Performance Studies

Non-Clinical Testing: The following testing was conducted (in compliance with FDA Guidance Class II Special Controls Guidance Document: Knee Joint Patellofemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses: Guidance for Industry and FDA) to demonstrate substantial equivalence of safety and efficacy with the predicate devices: Material Oxidation Index/Resistance Testing (ASTM F2102-17 ASTM F2003) Wear Testing with Particle Analysis (ISO 14243-2, ISO 14243-3 ASTM F1877-05)

Clinical Testing: Clinical testing was not necessary to determine substantial equivalence between the ATTUNE Polyethylene Fixed Bearing Tibia Inserts and Patella components and the predicate devices.

Key Results: The subject ATTUNE Polyethylene Fixed Bearing Tibia Inserts and Patella components with 8 year shelf life are substantially equivalent to the predicate ATTUNE Polyethylene Fixed Bearing Tibia Inserts and Patella components with 5 year shelf life.

§ 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.

Dear Mary Wood:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's

Summary of Technologies/ Substantial Equivalence Discussion

The purpose of this submission is to propose a change in shelf life from 5 years for the ATTUNE AOX Fixed Bearing Tibial Inserts for both CR (Cruciate Retaining) and PS (Posterior Stabilized) as well as the Medialized Dome and Anatomic Patellae components

There are no other modifications associated with the currently marketed products. The intended use, product design, principle of operation and materials are not impacted by this change.

Note: There have been no modifications made to the intended use, design, biocompatibility, materials, sterilization or packaging of the existing DePuy ATTUNE Knee System.

The only modification being sought via this Special 510(k) submission is a change in the shelf life of the ATTUNE C/R Fixed Bearing Insert, ATTUNE P/S Fixed Bearing Insert and the ATTUNE Medialized Dome and Anatomic Patellae components which are made from AOX Polyethylene that is gamma irradiated.

The ATTUNE Knee System is not an invitro-diagnostic device.

Submission Purpose

The purpose of this submission is to propose a change in shelf life from 5 years to 8 years for the ATTUNE AOX Fixed Bearing Tibial Inserts for both CR (Cruciate Retaining) and PS (Posterior Stabilized) as well as the Medialized Dome and Anatomic Patellae components. A complete list of the affected devices is provided as Exhibit A. The change will require an update to the shelf life indicated on the Labeling. Draft labeling is provided as Exhibit B.

There are no other modifications associated with the currently marketed product predicate ATTUNE Total Knee System. The intended use, product design, principle of operation and materials are not impacted by this change.

Device Description

The ATTUNE CR Fixed Bearing Tibial inserts are available in sizes 1-10 and in thicknesses of 5, 6, 7, 8, 10, 12, 14, 16, and 18mm. They are manufactured from AOX ultra high molecular weight polyethylene.

The ATTUNE PS Fixed Bearing Tibial Inserts are available in sizes 1-10 and in thicknesses of 5, 6, 7, 8, 10, 12, 14, 16, 18, 20, and 22mm. They are manufactured from AOX ultra high molecular weight polyethylene.

The ATTUNE Medialized Dome and Medialized Anatomic Patellae are available in sizes 29, 32, 35, 38. and 41mm. They are manufactured from AOX ultra high molecular weight polyethylene.

The proposed change to the shelf life of the subject AOX components will have no impact to the predicate, ATTUNE Knee System (K101433, K111433, K103756, K140881) which are intended for both cemented and noncemented use.

Materials

The subject ATTUNE Fixed Bearing Tibial Inserts and Patellae components are manufactured from AOX Polyethylene. This change proposes a shelf life change from 5 to 8 years; no material or sterilization changes are proposed.

Design

No design changes are proposed for this submission. The change is to extend the shelf life of the existing ATTUNE AOX Fixed Bearing Tibial Inserts and Patellae components from 5 years to 8 years.
