Primary and secondary osteoarthritis relates to inflammatory processes and inflammatory mediators and is destructive to the articular cartilage. Omega-3 is known to be an alternative treatment for rheumatoid arthritis due to the anti-inflammatory effect. This study is an experimental study with simple random sampling using 36 Wistar mice, which were divided into an intervention group and a control group, to understand the effect of omega-3 in slowing progress cartilage destruction in knee joint

The intervention group received oral omega-3 every day while the control group did not. Samples from the knee joint were extracted to evaluate the cartilage destruction histopathologically. Results were then analyzed using the Mann-Whitney test and a significant difference of the osteoarthritis grades was identified between the intervention group and the control group on day 7 (p=0.003), day 14 (p=0.003), and day 21 (p=0.003). In addition, a significant difference in the osteoarthritis grading changes was also found between the study group and the control group on day 7 and day 21 (p=0.004). Hence, omega-3 has the ability to slow down the histopathological cartilage destruction progress in mice with knee joint osteoarthritis.
