Study population: JOURNEY™ II UNI Unicompartmental Knee System (UKS) in patients with non-inflammatory degenerative joint disease (NIDJD) of the knee requiring either medial or lateral compartment knee replacement.

Who may be able to join

  • Subjects must meet all of the following criteria for inclusion in the study.
  • Unicompartmental, NIDJD, including OA, traumatic arthritis, or avascular necrosis.
  • Eighteen (18) years of age or older at the time of surgery.
  • Skeletally mature in the judgement of the PI.
  • Has met an acceptable preoperative medical clearance and is free of (or acceptably managed) cardiac, pulmonary, hematological, infection, or other conditions that would pose an excessive operative risk.
  • Willing and able to participate in required follow-up visits at the investigational site and to complete study procedures and questionnaires.
  • Consented to participate in the study by signing the EC-approved ICF.

Who cannot join

  • Subjects meeting any of the following criteria must be excluded from participation in the study.
  • Correction of functional deformity.
  • Revision procedures where other treatments or devices have failed.

About this study

Official title: A Prospective, Multicenter Post-Market Clinical Follow-up Study to Evaluate the Safety and Performance of the Journey™ II UNI Unicompartmental Knee System

This clinical study will evaluate the early to midterm safety and performance of the JOURNEY™ II UNI UKS in patients with non-inflammatory degenerative joint disease of the knee requiring lateral or medial knee compartment replacement. Clinical, radiographic, health economic and safety outcomes will be evaluated.

Read the detailed description

To assess the safety and performance of the JOURNEY™ II UNI UKS in patients with unicompartmental degeneration of the knee by demonstrating non-inferiority of the cumulative percent implant survival in subjects with the JOURNEY™ II UNI UKS implanted, compared to a literature reference rate of 91.7% (AOA annual report 2015)12 at 5 years.

Being tested
Journey™ II UNI Unicompartmental Knee System

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Journey™ II UNI Unicompartmental Knee SystemDevice

    Journey™ II UNI UKS is a CE Marked medical device. The device has been designed to treat both medial and lateral unicompartmental disease.

    It is a comprehensive system designed to allow surgeons to perform UKA. It is comprised of the following anatomic components: Oxidized zirconium femoral components Titanium tibial components with a grit-blasted surface Polyethylene tibial insert components The device is asymmetric and is available in oxidized zirconium to reduce wear and increase implant longevity.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Implant survival 5 years postoperatively

    Measured: 5 years

Secondary outcomes (2)
  1. Device-related adverse events

    All AEs will be collected and reported

    Measured: 5 year

  2. Radiographic assessments

    To assess changes in implant fixation and bone integrity, an evaluation will be performed based upon comparison of Antero posterior and Lateral radiographs over multiple time-points. Radiographs will be also evaluated for radiolucencies, osteolysis, implant positioning, implant migration, implant loosening, periprosthetic fracture, wear of the articulating surfaces of replacement components

    Measured: 5 year

Questions about this trial

What is this clinical trial studying?

An observational study of Non-inflammatory Degenerative Joint Disease (NIDJD) of the Knee, run by Smith & Nephew, Inc. at 6 sites in 3 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States, Italy, Poland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Implant survival 5 years postoperatively (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Feb 2026.
