The document describes a mechanical knee implant with minor design modifications and provides mechanical testing results. There is no mention of AI or ML in the intended use, device description, or performance studies.
Yes
The device is a total knee replacement system, which is used to treat conditions like arthritis and failed joint replacements, making it a therapeutic device for alleviating symptoms and restoring function.
No
This device is a total knee replacement system, which is a therapeutic device intended for surgical implantation to treat conditions like arthritis and failed previous surgeries. It is not designed to diagnose diseases or conditions.
No
The device description explicitly states it consists of physical components (tibial baseplate, inserts, femoral components, patella components) made of materials like polyethylene and titanium alloy, and mentions mechanical testing of these components. This indicates it is a hardware medical device, not software-only.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device used for surgical implantation to replace knee components in patients with various forms of arthritis and failed previous surgeries. This is a therapeutic device, not a diagnostic one.
- Device Description: The description details physical components like tibial baseplates, inserts, and femoral components, all designed for surgical implantation.
- Lack of IVD Indicators: There is no mention of the device being used to examine specimens from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
Therefore, this device falls under the category of a surgical implant or prosthetic device, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
Total knee components are indicated for rheumatoid arthritis; post-traumatic arthritis, osteoarthritis, or degenerative arthritis; failed osteotomies, unicompartmental replacement, or total knee replacement. Posterior stabilized knee systems are designed for use in patients in primary and revision surgery, where the anterior and posterior cruciate ligaments are incompetent and the collateral ligaments remain intact. The Journey II Total Knee system components are indicated for use only with cement and are single use devices.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Mechanical testing has been conducted to address the locking mechanism design change. The following verification testing has been conducted:
- Component Interlock Strength of the Tibial Insert Locking Mechanism ●
- Fatigue Strength Testing Of The Tibial Metal Base Tray, Cement And ● Polyethylene Insert Construct - Rationale
- Tibial Base Fatigue Testing- FEA
A review of the results indicates that the Journey II XR tibial baseplate and inserts are equivalent to the existing, legally marketed predicate devices with regards to mechanical performance and that there are no new issues related to the safety and effectiveness of the subject devices. Clinical data was not needed to support the safety and effectiveness of the subject devices.

§ 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 Mr. Sheals:
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. 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.
