The Regenerative Clinic's view on this research

Mr Nick Savva “This is an interesting complex meta-analysis of treatment of chronic plantar fasciitis with steroid injections, blood products (including PRP). It shows that all 3 are effective at reducing pain at 3 and 6 months with PRP and shockwave most effective. Shockwave takes a little longer to take effect. Suggestion that higher power shockwave and multiple PRP injections more likely to be effective.”

Abstract

Objective: To compare the efficacy of autologous blood-derived products (ABPs), CSs and shock-wave (SW) therapy in the treatment of plantar fasciitis.

Methods: Electronic databases were searched for studies that compared ABPs, CSs and SW therapy for the treatment of plantar fasciitis, published up to June 2014. The primary and secondary outcomes were reduction in visual analogue scale (VAS) score at 3 and 6 months and odds ratio of treatment success, respectively. Groups were compared by traditional pair-wise meta-analysis and by network meta-analysis.

Results: Seven randomized controlled trials and three quasi-experimental studies that included 604 patients were enrolled. Pair-wise meta-analysis indicated a trend favouring ABPs over CSs regarding VAS reduction at 3 months; this benefit was significant in a subgroup analysis of platelet-rich plasma (PRP) vs CSs. There were no significant between-group differences in VAS reduction at 6 months and in treatment success. Network meta-analysis showed that ABPs had the highest probability of being the best treatment at 3 months, but ABPs were slightly inferior to SW for VAS reduction at 6 months. Although SW therapy had the highest likelihood of treatment success, the between-group differences in probabilities were less remarkable than those for pain reduction at 3 and 6 months.

Conclusion: ABPs, followed by CSs, were best in providing relief from pain at 3 months. SW therapy and ABPs had similar probabilities of providing pain relief at 6 months, and were better than CSs at that time. Subgroup analysis indicated that an ABP regimen consisting of platelet-rich plasma improves treatment efficacy.
