Intended Use
The Triathlon® Screw-fixation tibial baseplates are intended for use in primary and revision total knee arthroplasty to alleviate pain and restore function. All total knee components presented in this submission are provided sterile for single-use. General Total Knee Arthroplasty (TKR) Indications: - Painful, disabling joint disease of the knee resulting from: noninflammatory degenerative joint disease (including osteoarthritis, traumatic arthritis, or avascular necrosis), rheumatoid arthritis or post-traumatic arthritis. - Post-traumatic loss of knee joint configuration and function. - Moderate varus, valgus, or flexion deformity in which the ligamentous structures can be returned to adequate function and stability. - Revision of previous unsuccessful knee replacement or other procedure. - Fracture of the distal femur and/or proximal tibia that cannot be stabilized by standard fracture management techniques. Additional Indications for Posterior Stabilized (PS) Components: - Ligamentous instability requiring implant bearing surface geometries with increased constraint. - Absent or non-functioning posterior cruciate ligament. The Triathlon® Screw-fixation Tibial Baseplates are intended for cementless use only.
Device Description
The tibial baseplates of the Triathlon® Total Knee System has been modified to include a screwfixation option for use with existing Triathlon® Total Knee components. The subject tibial baseplate is porous coated and will be available with and without Howmedica Osteonics' Periapatite (PA) coating. The Triathlon® fixed bearing cementless tibial baseplates are compatible with Triathlon® CR, PS, and CS tibial inserts and patellae. The Triathlon® components proposed in this submission are manufactured from cast cobalt chrome and have a cobalt chrome porous coating, available with and without a peri-apatitie coating. The Triathlon® tibial component is fixed bearing and will be provided in sizes 1 through 8. Compatible cobalt chrome bone screws are also included in this submission in 6.5mm diameter with lengths of 16mm, and 20mm to 60mm in 5mm increments.
More Information

Not Found

No
The 510(k) summary describes a modified tibial baseplate for a total knee replacement system. The description focuses on material composition, fixation method (screw-fixation), and compatibility with existing components. There is no mention of any software, algorithms, image processing, or data analysis that would suggest the use of AI or ML. The "Mentions AI, DNN, or ML" and "Mentions image processing" fields are explicitly marked as "Not Found".

Yes
The device is a knee implant designed to alleviate pain and restore function in individuals with painful and disabling joint disease of the knee, which aligns with the definition of a therapeutic device.

No

The device is described as a component for total knee arthroplasty, which is a surgical procedure to alleviate pain and restore function in a damaged knee joint. It is a prosthetic implant, not a tool used to diagnose medical conditions.

No

The device description clearly describes physical components made of cast cobalt chrome, including tibial baseplates and bone screws. This indicates a hardware-based medical device, not a software-only one.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
  • Device Description: The description clearly states that the Triathlon® Screw-fixation tibial baseplates are implants used in total knee arthroplasty. They are physical components inserted into the body to replace damaged knee joints.
  • Intended Use: The intended use is to alleviate pain and restore function in the knee joint through surgical implantation.

The device is a surgical implant, not a diagnostic tool that analyzes biological samples.

§ 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.

Dear Mr. Haro:

Re:

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 such 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); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
