Sampling Biomarkers in Meniscus Injury to the Knee
An observational study of Cartilage Diseases, run by Scuderi, Gaetano J., M.D..
Trial summary
The diagnosis of clinically-significant meniscal tears of the knee remains challenging, and it is unknown why only some injuries become painful. The limitations of diagnostic magnetic resonance imaging result in arthroscopy that is not always beneficial. Read more about this study

Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 90 years
- All sexes
- Healthy volunteers accepted
- Adult, Older adult
Study population: 68 patients with knee pain < 6 months with either acute or insidious onset who failed conservative management and elected arthroscopy. Adult volunteers with no history of knee pain.
Who may be able to join
- Adult patients with knee pain < 6 months with acute onset who had failed conservative treatment and elected for arthroscopic management. Indications for surgery included the presence of mechanical symptoms on history, a physical examination positive for McMurray's maneuver or joint line tenderness or both32, absence of severe joint space narrowing on plain radiography1 33, and the presence of grade III signal changes on MRI35 in an anatomic location consistent with the history and physical examination.
Who cannot join
- Less than 18 years old.
- Recent (within three months) intra-articular corticosteroid injection and past or current medical history of autoimmune disease (i.e. rheumatoid arthritis).
- In addition, no patients involved in a worker's compensation claim or personal injury litigation were enrolled in the study.
About this study
Official title: Diagnostic Utility of Cytokine Biomarkers in the Evaluation of Acute Knee Pain
The diagnosis of clinically-significant meniscal tears of the knee remains challenging, and it is unknown why only some injuries become painful. The limitations of diagnostic magnetic resonance imaging result in arthroscopy that is not always beneficial. Elucidation of biochemical pathways underlying pain in this condition may aid patient selection for surgery and provide pharmacotherapeutic targets. Cytokines may be involved in pain following meniscus injury and diagnostic cytokine assay may help physicians differentiate patients that may benefit from arthroscopy from those that may not.
Read the detailed description
Lavage of the operative and contralateral knee for comparison was performed under anesthesia prior to arthroscopy by the infusion of sterile saline into the knee joint followed by the immediate withdrawal into the syringe. Sixteen asymptomatic control subjects also contributed knee samples. The concentrations of 17 inflammatory cytokines/chemokines were measured using a multiplexed immunoassay panel. Pre-operative magnetic resonance imaging findings and cytokine assay results were compared to "gold-standard" intraoperative findings.

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 1 inclusion and 3 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 4 Feb 2009. Status can change between updates, so confirm with the study contact before making plans.
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.
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 4 Feb 2009.
