BACKGROUND Cartilage tissue has limited regenerative capacity and the management of cartilage defects has always been a challenging issue. Platelet-rich plasma (PRP) has been recently been used to improve healing of cartilage defects. In the present experiment, we aimed to investigate the effects of PRP on regeneration capacity as well as survival of the cartilage grafts in a rabbit model. M...

Background: Sensory nerve damage is the earliest leprosy sign which can lead to disability. Previous studies showed that autologous platelet-rich plasma (PRP) perineural blind injection stimulate sensory regeneration. Our study provided a safer and more accurate PRP agent delivery method through ultrasound-guided was first compare versus standard neuropathy treatment, neurotropic vitamin. This ...

OBJECTIVE Recent publications demonstrated improved outcomes during cardiac surgery when platelet rich plasma (PRP and platelet poor plasma (PPP) were applied during closure of the sternal and leg wounds [1,2]. These studies indicate a potential utility for PRP and PPP application in cardiothoracic surgery; however, further studies are necessary to truly measure the clinical efficacy of this in...

BACKGROUND Platelet-rich plasma (PRP) has been advocated as one treatment for cartilage tissue regeneration. To date, several different platelet-rich formulations have been available, but a deep knowledge of their composition and mechanism of action in a specific clinical use is needed. The aim of this study was to investigate the effect of various PRP formulations on human chondrocytes in vitr...

BACKGROUND Platelet rich plasma is known for its hemostatic, adhesive and healing properties in view of the multiple growth factors released from the platelets to the site of wound. The primary objective of this study was to use autologous platelet rich plasma (PRP) in wound beds for anchorage of skin grafts instead of conventional methods like sutures, staplers or glue. METHODS In a single c...

BACKGROUND Wound healing is a complex and dynamic process following damage in tissue structures. Due to extensive skin damage caused by burn injuries, this study determined the role of human adult peripheral and umbilical cord blood platelet-rich plasma on proliferation and migration in human skin fibroblasts. METHODS Platelet-rich plasma (5, 10, 15, 20 and 50% PRP) from human umbilical cord ...

OBJECTIVES After an injury, the biological reattachment of tendon to bone is a challenge because healing takes place between a soft (tendon) and a hard (bone) tissue. Even after healing, the transition zone in the enthesis is not completely regenerated, making it susceptible to re-injury. In this study, we aimed to regenerate Achilles tendon entheses (ATEs) in wounded rats using a combination o...

Autologous platelet-rich plasma (PRP) consists of cytokines, growth factors, chemokines, and a fibrin scaffold derived from the patient’s blood. The mechanism of action for PRP gel is considered to be the molecular and cellular induction of normal wound healing responses similar to that seen with platelet activation.[1,2] There are multiple indications of PRP therapy, but there are few controll...

OBJECTIVE Platelet-rich plasma (PRP) has the capacity to improve the bone-healing process. The aim of this pilot study was to investigate the occurrence of bone healing and the time taken to achieve this in patients submitted to medial opening wedge high tibial osteotomy (MOWHTO), comparing platelet-rich plasma with bone marrow aspirate to autologous iliac graft. DESIGN Twenty-five patients w...
