Abstract
Osteochondritis dissecans refers to the separation of osteochondral fragments from the bed of the joint surface. Definition of lesion goes by the existence of an open epiphyseal line in a juvenile form and the absence, representing an adult form. The treatment of osteochondritis dissecans depends on age, on the epiphyseal line, its length, location and stability of the lesion. A conservative treatment is preferred in juvenile cases; a surgical intervention may be necessary for unstable lesions and those not responding to conservative approaches. Showing no positive development in symptoms and physical status for six months, our 16-year-old male patient received two intraarticular platelet rich plasma injections three months apart, focusing on the lesion of steochondritis dissecans localized in the right knee. At the end of the 18th month, the patient did not show any limitation in his physical activities and radiographic examination confirmed the successful treatment. Having obtained positive results, we believe that PRP injections are a safe, simple, and minimally invasive treatment option for juvenile OCD which doesn\'t respond to conservative therapy before a surgical approach.
