Autologous Blood-Derived Products Compared With Corticosteroids for Treatment of Plantar Fasciopathy: A Systematic Review and Meta-Analysis.

OBJECTIVE

This review article evaluated the efficacy of autologous blood-derived products, including whole blood and platelet-rich plasma, in reducing pain and improving function compared with corticosteroids for plantar fasciopathy patients.

DESIGN

Literature comparing autologous blood-derived product and corticosteroids for the treatment of plantar fasciopathy was systematically reviewed. Twelve randomized controlled trials and four quasi-experimental studies were included. The visual analog scale pain score and American Orthopedic Foot and Ankle Society hindfoot score were evaluated at 1.5, 3, and 6 mos' follow-up. Subgroup analyses were performed concerning platelet-rich plasma preparation techniques, injection regiments, and study designs.

RESULTS

Corticosteroids were found to reduce pain more effectively than whole blood at 1.5 and 3 mos, but the effect disappeared at 6 mos. Platelet-rich plasma reduced pain more effectively at 6 mos' postinjection than corticosteroids. However, there was no significant difference in the American Orthopedic Foot and Ankle Society score between platelet-rich plasma and corticosteroids injections at any time point. In the subgroup analyses, pain was significantly reduced at 6 mos by self-prepared platelet-rich plasma, one-step separation platelet-rich plasma, platelet-rich plasma of more than 3 ml, and platelet-rich plasma without local analgesics.

CONCLUSIONS

The results of this meta-analysis suggest that platelet-rich plasma may provide a long-term effect in relieving pain in plantar fasciopathy patients.
