SUMMARY
This experimental study was performed to determine the effects of intraarticular hyaluronic acid (HA) and
methyl prednisolone acetate (MPA) in inflammatory arthritis. 0.2 ml1% formaline were injected to the posterior
right knee joints of 40 male rats. One week after the injections, 10 rats were killed and arthritis was determined
histopathologically. The remained 30 rats were divided to three groups. First group received intraarticularly
0.05 ml HA (HA group), second group 0.05 ml MPA (MPA group) and third group 005 ml saline as controls.
The injections were performed at 7., 14. and 21. days after the arthritis. 15 days after the end of these
treatments, rats were killed and sections were examined histopathofogically.
There was no significantly difference in synovial tissue healing between HA and control groups (p>0.05).
Synovial tissue healing was significantly high in MPA group compared to the control group (p<0.05). However
in comparing the two treatment groups (MPA and HA groups) there was not any significant difference
(p>0.05).
It was concluded that although intraarticular MPA seems more effective on synovial tissue healing in
inflammatory arthritis it has no evident superiority to HA.
