The 510(k) summary describes a mechanical knee implant system and surgical instruments. There is no mention of software, algorithms, or any technology that would suggest the use of AI or ML. The performance studies are focused on mechanical testing and biocompatibility.
Yes
The device is a unicondylar femoral and tibial implant system for partial knee replacement, which is a therapeutic intervention for conditions like osteoarthritis.
No.
The device is a unicompartmental knee implant system, which is a therapeutic device intended for partial knee replacement. It is used to treat conditions like osteoarthritis and is not designed to diagnose diseases or conditions.
No
The device description clearly outlines physical components made of Oxinium, Titanium alloy, and cross-linked polyethylene, along with surgical instrumentation. 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:
- Intended Use: The intended use clearly states that the device is a unicompartmental knee implant used for restoring a knee compartment affected by various conditions like osteoarthritis, traumatic arthritis, avascular necrosis, etc. This is a surgical implant, not a device used to examine specimens derived from the human body.
- Device Description: The description details the physical components of the implant (femoral implant, tibia baseplate, articular insert) and the surgical instruments used for implantation. This aligns with a surgical device, not an IVD.
- Lack of IVD Characteristics: There is no mention of the device being used to test or analyze biological samples (blood, urine, tissue, etc.) or to provide information about a patient's health status based on such analysis.
- Performance Studies: The performance studies focus on mechanical testing, biocompatibility, and pyrogenicity, which are relevant to surgical implants, not IVDs.
Therefore, the Journey II Unicompartmental Knee System is a surgical implant, not an In Vitro Diagnostic device.
N/A

Device Description
The subject of this Special 510(k) is the Journey II Unicompartmental Knee System (Journey II UK). The subject device is a unicondylar femoral and tibial implant set for treatment of unicompartmental osteoarthritis. The device is intended for appropriate unicondylar, medial or lateral, ACL and PCL preserving joint treatment (partial knee replacement).
Components of this premarket notification consist of a femoral implant, tibia baseplate, modular articular insert, and requisite US Class II surgical instrumentation required will consist of femoral instruments used to make appropriate resections to prepare the femur for said implants and tibial instruments used to make a planar resection and implant preparation of the proximal tibia.
The Journey II UK is a line extension of the Smith & Nephew Unicompartmental Knee line, incorporating previously cleared Smith & Nephew products. It contains design aspects of the existing Journey II Uni Tibial Baseplate and Inserts (S.E. K152315), the Journey Uni (S.E. K102069), and the ZUK (S.E. K160738).
Femoral components are manufactured from Oxinium (Zr-2.5Nb), and feature ten sizes each in left medial/right lateral and right medial/left lateral side (hand) configurations.
Tibial baseplates are manufactured from Titanium alloy (Ti-6Al-4V). They are available in:
- . Ten sizes of implant with a medial primary / lateral secondary use offered in both left and right handedness (listed henceforth as "medial primary"), and
- . Eight sizes of implant with a lateral primary / medial secondary use offered in both left and right handedness (listed henceforth as "lateral primary").
Each are expected to be used in its primarily listed compartment most often, but are designed for use in either medial or lateral compartments.
Modular articular implants are manufactured from cross-linked polyethylene (XLPE) and are available in medial and lateral configurations for use with corresponding baseplate. They are symmetric for use in either right or left hand.

Identification. A knee joint femorotibial metal/polymer non-constrained cemented prosthesis is a device intended to be implanted to replace part of a knee joint. The device limits minimally (less than normal anatomic constraints) translation in one or more planes. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral condylar resurfacing component or components made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components made of ultra-high molecular weight polyethylene and are intended for use with bone cement (§ 888.3027).(b)
