Abstract:

BACKGROUND: Autologous platelet-rich plasma is a platelet concentrate obtained by centrifugation of autologous whole blood. Studies have proved that autologous platelet-rich plasma can promote bone and cartilage repair, tissue repair, and vascular regeneration, and it is widely used in various disciplines such as stomatology, orthopedics, sports medicine, plastic cosmetology and dermatology.

OBJECTIVE: To observe and discuss the clinical effect of free fibular transplantation combined with autologous platelet-rich plasma in the treatment of avascular necrosis of the femoral head in young adults.

METHODS: From May 2014 to August 2018, 20 patients (24 hips) with early avascular necrosis of the femoral head in young adults were subjected to curettage of femoral head necrosis focus and free fibular transplantation with vascular anastomosis and platelet-rich plasma. Harris score system was used for evaluation at 12 months after operation to calculate the excellent and good rate and improvement rate of affected hips. Curative effect evaluation, imaging changes, follow-up results and complications of patients were recorded before and after operation.

RESULTS AND CONCLUSION: All 20 patients (24 hips) were followed up as scheduled. The follow-up time after operation was 1.0-2.5 years, with an average of 1.35 years. Harris score was used to evaluate curative effects, with excellent in 12 hips, good in 10 hips, fair in 1 hip, poor in 1 hip, and an excellent and good rate of 91.7%. There was a significant difference in the Harris score of the affected hip before operation and 12 months after operation (P=0.000). During the 12-month follow-up after the operation, 3 hips still had pain, 2 hips had imaging progress. Improvement grade was in 17 hips, unchanged grade in 5 hips, failure grade in 2 hips, with the improvement rate of 91.7%, and the clinical symptoms and signs of the patients were consistent with the imaging performance progress. Three patients (four hips) experienced numbness in the anterolateral thigh of the same side after operation, and completely recovered to normal after 3 months. One patient (one hip) underwent hip replacement 18 months after operation for avascular necrosis of femoral head (ARCO stage IV). No complications such as incision nonunion, infection and venous thrombosis were found. These results indicate that the anastomosed fibular graft combined with autologous platelet-rich plasma has good short-term clinical effect and high excellent rate in the treatment of early avascular necrosis of the femoral head.
