Abstrakt		The purpose of this study was to determine if the use of platelet gel (PG) does accelerate early graft vascularisation after anterior cruciate ligament (ACL) reconstruction. Platelet gel was produced from the platelet rich plasma (PRP), prepared from a unit of whole blood in Autologus Platelet Separator. PG was applied locally. Fifty patients were included, 25 in the platelet and 25 in a control group. We quantitatively evaluated the process of revascularization in the zone of osteoligamentous interface in the bone tunnels and in the intraarticular part of the graft. Contrast enhanced magnetic resonance imaging (MRI) studies were carried out at 4-6 and 10-12 weeks post surgery. At first control (4-6 weeks), patients treated with PG demonstrated a significantly higher level of vascularization in osteoligamentous interface (0.33+/-0.09), as compared with the control group (0.16+/-0.09), p<0.001. In the intraarticular part of the graft we found no evidence of revascularization in both groups. At the second control (10-12 W),the level of vascularisation decreased in platelet group (0.20+/-0.13) and increased in control group (0.17+/-0.10). In the intraarticular part of the graft we found minimal levels of revascularization but no differences among groups. The PG, applied locally, can enhance the early revascularization of the graft in the zone of osteoligamentous interface in bone tunnel after anterior cruciate ligament reconstruction.
