But it may affect the kids as a secondary type when kids were administered some groups of drugs such as quinolones which cause cartilage deformations and predispose to secondary type of osteoarthritis. This study aims to investigate the protective effect of glucosamine and chondroitin alone and in combination in the treatment of arthritis in Juvenile Rats. This study was applied on 5 groups of juvenile wistar rats, which divided as: normal group, control group, the group of GA, group of CS, the group of combination between GA+CS. At the end of the study all of rats were killed, then measurement of maximum extension of the right knee were performed, also histological and functional analysis of the articular cartilage of the knee were performed. Control group showed the degenerative changes as compared to the normal group, which is improved into the groups of GA, CS, which distinguished from the combination group. This study shows that GA and CS have protective effect able to opposite the destructive effect of quinolone on immature cartilages
