We investigated the correlation of plasma amino acid concentrations and the effects of glucosamine and fish collagen peptide (FCP) on osteoarthritis (OA). OA was induced according to the rabbit anterior cruciate ligament transection (ACLT) model. After surgery, the rabbits were orally administered FCP (F group), glucosamine (G group) or both (FG group) for 4 weeks. The control group (C group) was not administered anything. Blood was collected before surgery (pre-ACLT) and before euthanasia (post-ACLT). Changes in the alanine, threonine and methionine concentrations were significant between pre- and post-ACLT. The correlation between the histological assessment and arginine concentration post-ACLT was significant. These findings indicate that measurement of plasma amino acids is useful for evaluation of the efficacy of intervention for OA.
