How Lipedema Affects Knee Osteoarthritis

Official title: The Effect of Lipedema on Knee Osteoarthritis: A Cross-Sectional Analysis of Clinical Symptoms and Ultrasonographic Findings

Run by Izmir Democracy University · NCT07575555 · Data updated 2026-11-12

This study compares people with knee osteoarthritis who have lipedema to those with osteoarthritis but without lipedema to see if lipedema changes knee pain and structure.

Is this trial a fit for you?

Likely a good fit

Women aged 30-65 with clinically and radiologically confirmed knee osteoarthritis, with or without lipedema, who agree to participate.

Probably not a fit

Patients with knee osteoarthritis who do not have lipedema may not experience a differential benefit from this study, which is designed to compare groups rather than provide a therapeutic intervention.

What this trial studies

This observational study will compare two groups of women aged 30-65 with knee osteoarthritis: those who also have lipedema and those who do not. The researchers will look at clinical symptoms and ultrasonographic measurements to determine the independent impact of lipedema on knee osteoarthritis. By analyzing these factors within the same osteoarthritis context, the study aims to inform earlier diagnosis and targeted rehabilitation strategies. No interventions are described; the study focuses on comparative assessment and characterization. The investigation is conducted at Izmir Democracy University in Izmir, Turkey.

Why it matters

Potential benefit: If lipedema is shown to influence knee osteoarthritis, patients may receive earlier diagnosis and more tailored rehabilitation approaches.

How similar studies have gone: Few studies have examining lipedema's specific impact on knee osteoarthritis, making this approach relatively novel.
