About this study
The registry will capture prospective data on patients receiving pain management for chronic pain due to knee osteoarthritis (OA) or pain optimization for knee arthroplasty due to knee OA. The OA pain therapies may include cryo nerve block, radiofrequency ablation (RFA), intra-articular (IA) corticosteroids, viscosupplementation, opioids, and others (e.g., non-steroidal anti-inflammatory drugs [NSAIDs]).
- Conditions
- Knee Osteoarthritis
- Being tested

Questions about this trial
What is this clinical trial studying?
An observational study of Knee Osteoarthritis, run by Pacira Pharmaceuticals, Inc at 19 sites in United States.
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 3 inclusion and 2 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: looking for participants now, as of the sponsor's last update on 23 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 19 sites in United States. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Kate Fasel, BSN (1-520-490-5355, IGOR@pacira.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pain intensity and interference scores via NRS (Numeric Rating Scale) (time frame: 18 months). The study lists 15 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05495334, which also lists 1 linked publication.
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 23 Jul 2026.
