The document describes a traditional knee implant system and its mechanical testing. There is no mention of AI or ML in the intended use, device description, or performance studies.
Yes
The device is a total knee system indicated for use in primary total knee arthroplasty to treat painful, disabling joint disease, loss of knee joint configuration and function, and moderate deformities, aiming to improve stability and function of the knee. These are all therapeutic actions.
No
The TRAX® CR Total Knee System is a prosthetic implant used for total knee arthroplasty, not a device designed to identify or diagnose a disease or condition. Its purpose is to replace a damaged knee joint.
No
The device description clearly states it consists of physical components: a femoral component, a tibial implant (baseplate and insert), and a patellar component. It also mentions implantation with bone cement and the use of x-ray templates and trial implants, all indicative of a hardware-based medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical implant for replacing a damaged knee joint. This is a therapeutic device, not a diagnostic one.
- Device Description: The description details the components of a knee prosthesis (femoral component, tibial implant, patellar component). These are physical implants used in surgery.
- Lack of Diagnostic Elements: There is no mention of analyzing samples from the human body (like blood, urine, tissue) or providing information for diagnosis.
- Performance Studies: The performance studies listed are related to the mechanical properties and durability of the implant, not diagnostic accuracy.
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device does not fit that description.

Intended Use / Indications for Use
The TRAX® CR Total Knee System is indicated for use:
- In primary total knee arthroplasty (TKA) as a result of:
- Painful, disabling joint disease of the knee resulting from degenerative arthritis, rheumatoid arthritis or post-traumatic arthritis.

- Moderate varus, valgus or flexion deformity in which the ligamentous structures can be returned to adequate function and stability.
- In revision of previous osteotomy,
- In revision of previous unsuccessful unicompartimental or femoro-patellar knee.
The TRAX® CR Total Knee System is for single use only and is intended for implantation with bone cement only.

Device Description
The TRAX® CR Total Knee System belongs to the category of Cruciate Retaining (CR) total knee prostheses (only anterior-cruciate is sacrificed).
The TRAX® CR Total Knee System is intended for use as a semi-constrained replacement system. It consists of a femoral component, a tibial implant and a patellar component. The tibial implant consists of two components: bearing insert and tibial baseplate. The patellofemoral joint may be preserved or resurfaced with the patellar resurfacing implant.
The selection of the appropriate implants can be made by using the recommendations of the surgical technique and by using the x-ray templates and trial implants supplied with the instrumentation.

§ 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 J.D. Webb:
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 (the 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.
