Intended Use

Unicompartmental knee implants are indicated for restoring either compartment of a knee that has been affected by the following: - Noninflammatory degenerative joint disease including osteoarthritis, traumatic arthritis, or avascular necrosis; - Correction of functional deformity: - Revision procedures where other treatments or devices have failed; and - Treatment of fractures that are unmanageable using other techniques. Unicompartmental knee implants are single use only and are intended for implantation only with bone cement.

Device Story

Journey II Uni tibial baseplate and insert system; modification of existing Journey Uni components. System comprises titanium alloy (Ti-6Al-4V) tibial baseplates and cross-linked polyethylene (XLPE) articular inserts. Designed for use with existing Journey Uni or GENESIS Uni femoral components. Implanted by orthopedic surgeons in clinical settings to restore knee compartment function. Modifications include updated insert locking mechanism, articular surface geometry, sizing, and cemented surface characteristics. Device functions as a cemented, semi-constrained knee prosthesis. Mechanical performance verified via fatigue testing, shear load testing, and contact area analysis. Provides structural support and articulation for patients with degenerative joint disease or fractures; intended to improve joint function and reduce pain.

Clinical Evidence

Bench testing only. No clinical data required. Mechanical verification included unsupported baseplate fatigue testing, static testing of insert locking mechanism (ML/AP shear load), fully supported fatigue/cement adhesion testing, and contact area analysis.

Technological Characteristics

Materials: Ti-6Al-4V tibial base, cross-linked polyethylene (XLPE) inserts. Design: Unicondylar, semi-constrained, cemented prosthesis. Locking mechanism: Anterior/Posterior snap fit. Sterilization: ETO/Gamma. Connectivity: None (mechanical implant).

Indications for Use

Indicated for patients requiring restoration of a knee compartment due to noninflammatory degenerative joint disease (osteoarthritis, traumatic arthritis, avascular necrosis), functional deformity, failed prior treatments, or unmanageable fractures. Single use only; requires bone cement.

Regulatory Classification

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).

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.
