Intended Use

Candidates for total knee replacement include patients with and/or severely disabled joint resulting from osteoarthritis, post-traumatic arthritis, rheumatoid arthritis, or a failed previous implant.

Device Description

The subject device is an all polyethylene tibia component made from AOX Polyethylene that mates with existing ATTUNE cemented (K101433) and cementless (K140881) femoral components, and existing ATTUNE patella components (K103756).

AI/ML Overview

The document provided is a 510(k) premarket notification for a medical device, the ATTUNE All Polyethylene Tibia, and does not contain information about acceptance criteria or a study proving the device meets said criteria in the context of AI/ML performance.

Instead, the document focuses on demonstrating substantial equivalence to existing predicate devices based on non-clinical performance data.

Here's why the requested information cannot be extracted from this document:

  • Device Type: The device is a "Knee Joint Patellofemorotibial Polymer Semi-Constrained Cemented Prosthesis," which is a physical implant for total knee replacement, not a software or AI/ML-driven device.
  • Study Type: The studies mentioned are "non-clinical tests" related to mechanical properties and material performance of the physical implant (e.g., Contact Area/Pressure, Wear, Constraint on tibiofemoral interface, Spine Fatigue, C2 Fixation Testing, Range of Motion, and bacterial endotoxin testing). These are not studies to evaluate AI/ML performance.
  • Lack of AI/ML Specifics: There is no mention of AI, machine learning, algorithms, or any form of software performance evaluation.
  • Clinical Testing: The document explicitly states: "No clinical testing was conducted to demonstrate substantial equivalence." This further indicates that the type of clinical performance study typically associated with AI/ML device validation (e.g., impact on human readers, standalone performance) was not performed.

Therefore, I cannot provide the requested information about acceptance criteria, device performance tables, sample sizes for test/training sets, data provenance, expert ground truth, adjudication methods, MRMC studies, or standalone algorithm performance, as these concepts are not applicable to the content of this 510(k) submission for a knee implant.

Dear Kellie Myers:

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.

{1}------------------------------------------------

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 requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

§ 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.
