Subject of this Traditional 510(k) Premarket Notification are the Smith & Nephew, Inc. Total Knee System Instruments. The subject devices are accessory devices and are intended to be used to assist in the implantation of Smith & Nephew Total Knee Systems and their cleared Indications for Use. Smith & Nephew Total Knee System Instruments can be organized into instrument families which are categorized as follows: Trials, Cutting Instruments and Cutting Guides; Cutting Blocks, Alignment and Sizing Instruments, Impactors and Handles, Clamps, Extraction, Torque, Instrument Guides, and Covers and Protectors.
This document is a 510(k) Summary of Safety and Effectiveness for the Smith & Nephew Total Knee System Instruments. It explicitly states that these instruments are "accessory devices" used to assist in the implantation of Smith & Nephew Total Knee Systems.
The document does not contain any information regarding acceptance criteria or a study proving the device meets those criteria, nor does it provide details about any AI-related performance metrics.
The content is focused on:
- Device classification and regulatory information.
- Listing predicate devices (previously cleared knee systems).
- Device description (types of instruments).
- Intended use and Indications for Use for various knee replacement types (Cruciate Retaining, Posterior Stabilized, Constrained, Hinged).
- FDA clearance letter.
Therefore, I cannot provide the requested information. The document is for mechanical surgical instruments, not an AI/Software as a Medical Device (SaMD) that would typically involve performance studies with ground truth and expert reviews for diagnostic accuracy.

Dear Mr. Rouss:
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. 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.
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 requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set

§ 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.
