Journey™ UNI Post Market Clinical Follow-Up

Study Purpose

This is a retrospective/prospective, open-label single cohort, multicenter study to collect relevant clinical data from 147 subjects with unicompartmental degeneration of the knee in whom the Journey UNI UKS was previously implanted.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Additional Details

The purpose of the current investigation is to assess the safety and effectiveness of the JOURNEY UNI Unicompartmental Knee System (UKS) in patients with non-inflammatory degenerative joint disease (NIDJD) of the knee who previously had the Journey UNI UKS implanted. This clinical study will prospectively evaluate the 36 and 60-month safety and performance of the JOURNEY UNI UKS in patients with NIDJD of the knee who required lateral or medial knee compartment replacement.
