Official Title: Diagnostic Utility of Cytokine Biomarkers in the Evaluation of Acute Knee Pain

Brief 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. 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.

Detailed Summary: 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.
