PLATELET RICH PLASMA RESULTS IN THE TREATMENT OF FEMUR HEAD AVASCULAR NECROSIS Femur Başı Avasküler Nekroz Tedavisinde Trombosit Zengin Plazma Sonuçları

ABSTRACTObjective: It has been observed that the number of patients with hip avascular necrosis who applied toour clinic after Covid-19 and steroid treatment in Covid-19 treatment has increased. It is emphasized inthe literature that core decompression therapy is effective in early stage femoral head avascular necrosis.Core it has been emphasized in many publications that the results of intraoperative platelet- rich plasma(PRP) application after decompression are effective. However, intraoperative the method of application ofplatelet- rich plasma (PRP) and its effectiveness in the post-Covid-19 period are not emphasized enough inthe literature. The aim of this study is to evaluate the effect of local platelet-rich plasma (PRP) administeredusing the new technique after core decompression to patients diagnosed with avascular necrosis.Material and Methods: Local platelet- rich plasma (PRP) was applied to 15 hips diagnosed with femoralhead avascular necrosis after core decompression with a new technique. Early results of the patients wereevaluated with Ficat and Harris hip scores.Results: An improvement was detected in the early clinical and Magnetic resonance (MR) findings of a totalof 15 hip avascular necrosis patients. Local treatment in patients with avascular necrosis with a medicalhistory of Covid-19 the feasibility of PRP was demonstrated.Conclusion: This study shows the importance of the intraoperative application method of platelet- richplasma (PRP) and that platelet- rich plasma (PRP) can also be applied to Covid-19 patients. But we believelong-term results are needed.
