Abstract
ObjectiveOsteoarthritis is caused by cartilage degeneration arising from cartilage degradation of type II collagen which synthesis also deteriorated. Nowadays, osteoarthritis is still difficult to handle because of the irreversibility and progressivity of the disease. Regenerative therapy offers a great challenge and better result for osteoarthritis treatment. This study aims to prove that the administration of recombinant platelet-derived growth factor-BB (rrPDGF-BB) with hyaluronic acid (HA) can stimulate the higher forms of chondrocyte and lower the YKL-40 levels as a specific marker of cartilage degradation in mouse knee osteoarthritis model. MethodThis was an experimental study, post-test only control group design using white Wistar rats as subjects that were induced by monosodium iodoacetate (MIA) to create osteoarthritis (OA). The treatment group was given treatment group was given rrPDGF-BB and HA, while no such treatment was given to the control group. The chondrocyte cell count was examined with routine histopathology, and YKL-40 levels were calculated by ELISA. ResultStatistical analysis using independent t-test showed that the mean difference in the number of cell counts of chondrocytes was significantly higher than the control group. While the mean difference of YKL-40 level in the treatment group was significantly lower compared to the control group with. ConclusionWe conclude that the administration of rrPDGF-BB and HA in mouse knee joint osteoarthritis model have a regenerative effect on knee joint cartilage characterized by a higher number of chondrocytes and lower YKL-40 levels.
