Objectives To systematically review the safety and efficacy of intraoperative local application of platelet-rich plasma in patients with femoral neck fracture.Methods Databases including The Cochrane Library, PubMed, Web of Science, WanFang Data, CBM, EMbase and CNKI were searched to collect randomized controlled trials (RCTs) on operation versus operation combined with platelet-rich plasma for patients with femoral neck fracture from inception to April 30th, 2017. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Then, meta-analysis was performed by RevMan 5.3 software.Results A total of 8 RCTs, including 916 patients with femoral neck fracture were enrolled in the analysis. The results of meta-analysis showed that compared with the group of internal fixation, the group of internal fixation combined with platelet-rich plasma could significantly shorten healing duration of fracture (MD=−2.18, 95%CI −3.37 to −0.99, P=0.000 3), improve the fracture healing rate (RR=1.14, 95%CI 1.03 to 1.25, P<0.000 01) and hip function score (MD=10.18, 95%CI 5.99 to 14.37, P<0.000 01), and effectively reduce the femoral head necrosis rate after operation (RR=0.35, 95%CI 0.22 to 0.57, P<0.000 1).Conclusion Current evidence shows that the method of internal fixation combined with platelet-rich plasma could effectively shorten healing duration, improve healing rate and hip function score, and reduce the rate of femoral head necrosis. Due to the limited quality of the included studies, more large scale, high-quality studies are required to verify the above conclusion.
