Abstract
Introduction and aim of the study: Osteoarthritis (OA) is a degenerative joint disease characterized by joint pain and progressive loss of articular cartilage. This study was conducted to evaluate the therapeutic effect of platelet-rich plasma (PRP) of the knee joint in a rat model of OA.
Materials and Methods:
Forty adult male albino rats, weighing 200-250 gm, were used in this study, ten rats used as donors to obtain PRP. The other thirty rats were divided into two main groups. Group I: The control group (15 rats) in which the rats were subdivided into three subgroups. Subgroups IA and IB were sacrificed 4 and 6 weeks after the beginning of the experiment. Subgroup IC left for 4 weeks then received intra-articular injection of PRP in the right knee joint which was repeated three times per week for 2 weeks then the animals were sacrificed. Group II (The experimental group) (15 rats) in which OA was induced by surgical induction of cartilaginous defect in the right knee joints. The rats of group II were subdivided into three subgroups. Subgroups IIA and IIB were sacrificed 4 and 6 weeks after induction of OA respectively. Subgroup IIC received intra-articular injection of PRP (0.2 ml) in the right knee joints 4 weeks after surgery. The injection was repeated three times per week for 2 weeks then the animals were sacrificed. The right joints from all groups were collected, decalcified and processed for histological studies. Specimens were also processed for transmission electron microscopic study. Morphometric and statistical measurements were done.
