OBJECTIVE: To assess the effect of intra-articular corticosteroids added to systemic antibiotics in experimental septic arthritis.
METHODS: Rabbits were injected intra-articularly by Staphylococcus epidermidis. Rabbits received no additional treatment and served as control (group 1), were treated with systemic antibiotics (group 2), or treated with systemic antibiotics and intra-articular corticosteroids (group 3). After 15 days animals were killed and joint histopathological-histochemical parameters were assessed.
RESULTS: All rabbits survived the experiment. The treated groups (2-3) had lower histological-histochemical scores in comparison with the untreated group (1). Group 3 had significantly lower scores in joint sections in comparison with group 2: (mean (SD) 6.5 (1.4) v 4.0 (1.0), p = 0.001 and 7.4 (2.6) v 4.2 (2.2), p = 0.01), because of lower damage expressed in clustering of chondrocytes, pannus formation, proteoglycan depletion, and synovitis.
CONCLUSION: Addition of local corticosteroids to systemic antibiotics in septic arthritis seems to be harmless, and improves joint histological-histochemical parameters in this experimental setting.
