Objectives:

Aim of the study is to evaluate incidence, characteristics and result of treatment due to primary knee septic arthritis in the city of Isparta.

Methods:

The patients who admitted to hospital for primary knee septic arthritis, treated with arthroscopic debridment and culture positive (Newman Grade A) were included between 2010-2011. Demographic, clinical, hematological, microbiological datas anad treatment methods were evaluated retrospectively.

Results:

There were 17 culture positive patient out of 39. Mean age was 54,7 (10- 89) years. When comorbidities were investigated 4 hypertension (HT), 3 diabetes mellitus (DM), 38 coronary artery disease (CAD), 28 chronic renal failure (CRF), 1 chronic obstructive pulmonary disease (COPD), 1 Behçet’s Disease and 1 romatoid arthritis (RA) were found. The culture results were determined as 15 Staphylococcus aureus, 1 Serratia marcescens and 1 Brucella spp.

Conclusions:

When the patients were investigated for a predisposing factor for septic arthritis, there was nothing for predisposing. We thought that high incidence of septic arthritis in this region is due to flouride concentration in tap water. There was high concentration of flouride (>1,5 mg/La) in tap water in past years. This concentration was lowered with municipal workout. Fluoride inhibate antibody formation and therefore supresses immunity. We concluded that high incidence of septic artritis in Isparta, especially age over 50, is related to high flouride level in tap water at past years.
