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 using prp...

background: the purpose of this study was to create biomaterial scaffolds like platelet-rich plasma (prp) and platelet-rich fibrin (prf) containing stromal cell-derived factor-1 (sdf1) as a chemokine to induce hyaline cartilage regeneration of rabbit knee in a full thickness defect. methods: we created a full thickness defect in the trochlear groove of thirty-six bilateral knees of eighteen mat...

conclusions it seems that applying prp is an effective therapeutic approach for wound healing, and faster wound healing is expected due to the presence of more platelets and growth factors. results at the end of study, the prp group showed a greater reduction in the edema ecchymosed discharge approximation (reeda) score compared to the control group (85.5% reduction in the prp group; 72% in the...

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 cen...

autologous fat transfer offers many qualities of a ideal soft tissue filler. main advantages of fat grafting ensue from the fact that the lipoaspirate tissue is an abundant source of regenerative pluripotential cells. however, the reported rates of fat cell survival vary greatly in the medical literature (10-90%). different techniques of harvesting, processing, and reinjecting the fat cells are...

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. meth...

patients and methods seventy patients with chronic partial supraspinatus tears in magnetic resonance imaging were randomized into two groups; prp (n = 35) and pt (n = 35). before the treatment, at the end of the treatment and at the 12th month after the end of the treatment, range of motion (rom), visual analog scale (vas) for pain, disabilities of arm, shoulder and hand questionnaire (dash), n...
