Da belastbare Daten zur Wirksamkeit von autologem plättchenreichem Plasma (engl. Platelet Rich Plasma/PRP) bei degenerativen Kniegelenkerkrankungen bislang fehlen, sprechen sich viele klinische Leitlinien gegen eine entsprechende Injektionsbehandlung aus. Dennoch kommt die Therapie in der Praxis zunehmend zum Einsatz. Eine randomisierte Doppelblindstudie (RESTORE) prüfte nun, ob Personen mit me...

Platelet preparations promote bone regeneration by inducing cell migration, proliferation and differentiation in the area of the injury, which are essential processes for regeneration. In addition, several studies have indicated that simvastatin (SIMV), widely used for the treatment of hypercholesterolemia, stimulates osteogenesis. The objective of this study was to evaluate the effects of trea...

BACKGROUND Platelet-rich plasma (PRP) has recently been postulated as a treatment for osteoarthritis (OA). Although anabolic effects of PRP on chondrocytes are well documented, no reports are known addressing effects on cartilage degeneration. Since OA is characterized by a catabolic and inflammatory joint environment, the authors investigated whether PRP was able to counteract the effects of s...

Platelet-rich plasma (PRP) contains a high concentration of thrombocytes and the -granules of platelets contain platelet-released growth factors. The usefulness of PRP for regeneration of bone and soft tissues has been reported previously. We firstly reported the efficacy of PRP prepared using the Magellan Autologous Platelet Separator System for intractable skin ulcers such as diabetic and ve...

Editorial Platelet rich plasma (PRP), also termed autologous platelet gel, plasma rich in growth factors (PRGF), platelet concentrate (PC), is essentially an increased concentration of autologous platelets suspended in a small amount of plasma after centrifugation. Basically, patient's blood is collected and centrifuged at varying speeds until it separates into 3 layers: platelet poor plasma (P...

BACKGROUND Autologous platelet concentrate has been used to improve the function and regeneration of injured tissues. Tendinopathies are common in clinical practice, although long-term treatment is required. On the basis of lead time, we compared the effect of using platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) in repairing rat Achilles tendon. METHODS The effectiveness of usi...

objective: to determine the effects of platelet rich plasma prp on healing rates of long bone non-:union: fracture. method: this was a randomized double-blind placebo controlled clinical trial being performed in a 12-month period. we included 75 adult (>18 years) patients suffering from long bone (femur, tibia, humerus and ulna) non-:union: fracture who were randomly assigned to receive 5ml prp...

Although mechanical stabilisation has been a hallmark of orthopaedic surgical management, orthobiologics are now playing an increasing role. Platelet-rich plasma (PRP) is a volume of plasma fraction of autologous blood having platelet concentrations above baseline. The platelet alpha granules are rich in growth factors that play an essential role in tissue healing, such as transforming growth f...
