Effects of laser on the synovial fluid in the inflammatory process of the knee joint of the rabbit.

Objective: The purpose of this study was to evaluate the effects of low-level laser (LLL) energy on the clinical signs of inflammation and the cellular composition of synovial fluid (SF) in the inflamed knee of the rabbit.

Background Data: There are few findings related to the effects of LLL on SF in inflammatory processes and there is little knowledge about the optimal parameters for reducing joint inflammation.

Materials And Methods: Inflammation in the right knee of 36 rabbits was induced by intracapsular injection (0.
