Biomechanical And Metabolic Changes Within Rabbit Articular Cartilage Following Treatment With Radiofrequency Energy

The effects caused to articular cartilage by the remote use of arthroscopically-delivered RF energy to soft tissues in the joint are unknown. This investigation reported the short and long-term effects of bRF and mRF energy on the biomechanical properties and metabolic activity of articular cartilage. In addition, the effect of Cosequin® therapy was addressed. Thirty New Zealand white rabbits were randomly assigned to one of two treatment groups (Group 1 - placebo; Group 2 - Cosequin®). Histopathology, cell viability, GAG synthesis, and mechanical function of the articular cartilage were compared between groups. Data were analyzed using a mixed model ANOVA (p=0.05). Immediate chondrocyte death was created by both RF devices. This damage was noted to be superficial and did not lead to the progressive deterioration of the extracellular matrix or mechanical function of the articular cartilage. Cosequin® therapy was unable to demonstrate significant differences compared to the control group.
