Abstract Objective: Core decompression bone grafting usually is used hip-preserving approach for osteonecrosis of femoral head (ONFH). Platelet-rich plasma (PRP) is an adjuvant therapy, combined with core decompression bone grafting for ONFH. However, it remains controversial. Therefore, its efficacy was systematically evaluated and meta-analysis in this study.Methods: Literature on core decompression bone grafting for ONFH was retrieved in CNKI, Wan Fang, PubMed, Embase, Cochrane Library and Web of Science from inception to March 2021. Review Manager 5.3 software and Stata 12.0 software were used for data synthesis.Results: A total of 10 RCTs were included. The results showed at final follow-up that, Harris hip score was significantly difference in the treatment group, adjuvant therapy with PRP (group A) better than the control group (group B), MD=7.53 [95%CI (5.29,9.77)],P < 0.00001. There was MD=-0.71[95%CI (-0.96, -0.46)], P < 0.00001, of visual analog scale (VAS) of hip pain between the two groups. The excellent and good rate of function of hip was 1.42-fold higher in group A than that in group B, RR=1.42, 95%CI (1.25,1.62), P<0.00001. The progression and total hip arthroplasty were showed improvements, RR=0.37,95%CI (0.21,0.65), P=0.0006 and RR=0.39,95%CI (0.18,0.85), P=0.02, respectively. Begg's and Egger's tests did not indicate publication bias.Conclusion: It was shown that the use of PRP combined with core decompression bone grafting improved the symptoms better than core decompression bone grafting only, and might delay progression and total hip arthroplasty. However, as the study’s limitations, it needed to be fully verified by more large-sample multicenter prospective clinical studies.

Background. As a pathological process, osteonecrosis of the femoral head (ONFH) is characterized by the avascularity of the femoral head, cellular necrosis, microfracture, and the collapse of the articular surface. Currently, critical treatment for early-stage ONFH is limited to core decompression. However, the efficacy of core decompression remains controversial. To improve the core decompression efficacy, regenerative techniques such as the use of platelet-rich plasma (PRP) were proposed for early-stage ONFH. As a type of autologous plasma containing concentrations of platelets greater than the baseline, PRP plays an important role in tissue repair, regeneration, and the differentiation of mesenchymal stem cells (MSCs). In this review, we present a comprehensive overview of the operation modes, mechanism, and efficacy of PRP for early-stage ONFH treatment. Methods. We searched for relevant studies in the PubMed, Web of Science, and Embase databases. By searching these electronic databases, the identification of either clinical or experimental studies evaluating PRP, MSC, core decompression, and ONFH was our goal. Results. Seventeen studies of PRP and avascular necrosis of the femoral head were evaluated in our review. Ten studies related to the possible mechanism of PRP for treating ONFH were reviewed. Seven studies of the operation modes of PRP in treating ONFH were identified. We reviewed the efficacy of PRP in treating ONFH systematically and made an attempt to compare the PRP operation modes in 7 studies and other operation modes in past studies for early-stage ONFH treatment. Conclusion. PRP treats ONFH mainly through three mechanisms: inducing angiogenesis and osteogenesis to accelerate bone healing, inhibiting inflammatory reactions in necrotic lesions, and preventing apoptosis induced by glucocorticoids. In addition, as an adjunctive therapy for core decompression, the use of PRP is recommended to improve the treatment of early-stage ONFH patients, especially when combined with stem cells and bone grafts, by inducing osteogenic activity and stimulating the differentiation of stem cells in necrotic lesions.

Purpose The aim of this study was to report the rate of survivorship in patients with osteonecrosis of the femoral head treated with core decompression in association with mesenchymal stem cells (MSCs) implantation, platelet-rich plasma (PRP) injection, and synthetic bone graft. Methods We evaluated 24 hips in 16 patients, according to Ficat classification, treated by core decompression, injection of PRP and MSCs, and backfilling of the core tract with synthetic bone graft. Survivorship was estimated using Kaplan–Meier curves. Results The survivorship of core decompression in association with the procedure is 50% at 75 months of follow-up. The survival rate was 80% for patients in early stage and 28.6% for patients in advanced stage at 75 months. When we compared Kaplan–Meier survival curves of patients in stage III + IV and patients in stage I + II, we noticed that the survival functions are statistically different (p < 0.05, log-rank test), particularly in stage I + II where we had a greater surviving core decompression, in comparison to patients in stage III + IV. Conclusion This technique is safe and good preliminary results were obtained in patients with early stages of the disease with no reported complications. Level of Evidence Level IV, therapeutic case series.
