Arthroplasty in patients with congenital hip dysplasia--early evaluation of a treatment method.

Background: Developmental hip dysplasia (DHD) is the most common cause of secondary hip osteoarthritis (OA). It often leads to OA in young, active and working adults. The aim of our study is to evaluate the results of THA in patients with DHD.

A side-effect induced by the combination of a demineralized freeze-dried bone allograft and leucocyte and platelet-rich plasma during treatment for large bone cysts: a 4-year follow-up clinical study.

During platelet activation over 30 growth factors are released from their alpha granules. By concentrating platelets, higher levels of growth factors are obtained and can be used to stimulate the healing processes. Moreover, during blood centrifugation, huge numbers of leukocytes and thrombocytes can be obtained to form leukocyte and platelet-rich plasma (L-PRP).
