Resumo
The use of platelet-rich plasma (PRP) in the treatment of articular cartilage defects induced experimentally in horses was studied. For this purpose, both patellofemoral joints of four animals were approached through arthroscopic surgery to perform a cartilage defect on the medial femoral trochlea. After 30 days of induction the eight joints were divided into two groups. Group 1 animals received intralesional and intra-articular treatment with PRP and Group 2 animals were treated only with saline solution. The clinical assessments, constituted by lameness signs and synovial fluid analysis, were performed before induction of injury (time zero) and every 15 days in 120 days, with last analysis on day 150. The macroscopic and morphologic analysis were performed at 0 and 150 days. During the experiment Group 1 animals showed improvement in lameness when compared to Group 2 animals. The macroscopic and morphological analysis showed a better tissue repair in the treated horses. Thus, the implantation of autologous PRP showed beneficial effects in the treatment of chondral lesions, experimentally induced in horses.
