Exploring ultrasound signs in knee septic arthritis

Exploratory Study of Ultrasound Signs of Native Septic Arthritis of the Knee

Poitiers University Hospital · NCT04952220

This study looks at how ultrasound images change over time in people with knee septic arthritis to see if these changes can help predict their recovery.

What this trial studies

This observational study aims to describe ultrasound abnormalities in patients with bacteriologically proven native septic arthritis of the knee at multiple time points: Day 0, Day 10, 6 weeks, 3 months, and 6 months. It will also investigate potential poor prognostic factors and associations between initial ultrasound findings and clinical outcomes, including the use of joint lavage. The study will involve regular ultrasound assessments to monitor changes and correlations with clinical and biological factors throughout the treatment period.

Who should consider this trial

Good fit: Ideal candidates include adults with bacteriologically confirmed native septic arthritis of the knee.

Not a fit: Patients with joint material present or those with tuberculosis-related arthritis may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the understanding and management of septic arthritis in the knee, leading to better patient outcomes.

How similar studies have performed: While there may be studies on ultrasound in arthritis, this specific focus on native septic arthritis is relatively novel.
