Abstract
|
|
|
Purpose: The purpose of this study was to retrospectively analyze the etiologic transition of the predisposing factors and organisms for septic arthritis of the knee.
Materials and Methods: Between January 1995 and December 2006, 122 cases of septic arthritis of the knee were retrospectively evaluated for the etiologic transition and causative organism with using the patients` medical records. We researched the incidence and causative factor of septic arthritis of the knee, which was diagnosed via the patients` symptoms, physical examinations, hematologic exams, culture studies & cytology of the joint fluid. We assessed the correlation of disease with age, the year the disease happened, the causative factors and the incidence.
Results: Septic arthritis of the knee was increased after 40 years old, and it also increased after 1998. The most common predisposing factor was intra-articular injection of the knee joint. Even though there were no detected organisms in 79 cases (64.8%), the most common causative organism was S. aureus (20.5%).
Conclusion: The most common etiologic factor of septic arthritis of the knee was an intra-articular injection. We should be prudent for using good aseptic technique and the correct procedure to reduce the secondary infection that`s recently due to increased invasive treatment of the knee joint.
