Effectiveness of dextrose prolotherapy for the treatment of chronic plantar fasciitis: A systematic review and meta-analysis of randomized controlled trials.

To systematically investigate the efficacy and safety of dextrose prolotherapy for treating chronic plantar fasciitis. EMBASE, PubMed, Scopus, and Google Scholar (from inception to December 9, 2021). Comprehensive review of randomized controlled trials investigating dextrose prolotherapy for chronic plantar fasciitis was done. Two investigators independently screened the titles, abstracts, and full texts and extracted data from eligible studies. The changes in visual analog scale (VAS) pain score, foot function index (FFI), American Orthopaedic Foot and Ankle Society (AOFAS) score, and plantar fascia thickness were analyzed. Reports of complications of the procedure were collected. Eight randomized controlled trials (RCTs) were included in the meta-analysis, analyzing 444 patients in total. The subgroup analysis showed that at short-term follow-up (<6 months) dextrose prolotherapy was more effective in reducing VAS pain score compared to the non-active treatment control group including exercise and normal saline solution (NSS) injection. However, there was no difference in the change of VAS pain score between dextrose prolotherapy and active treatment control group, which included extracorporeal shock wave therapy (ESWT), steroid injection, and platelet-rich plasma (PRP) injection. Dextrose prolotherapy was more effective in reducing FFI, increasing AOFAS score, and reducing plantar fascia thickness at short-term (<6 months) follow-up compared to other comparators. For long-term (≥6 months) follow-up, there was no significant difference in the change in VAS pain score and FFI between the dextrose prolotherapy group and other comparators. No serious complication was reported. Dextrose prolotherapy is an effective treatment of chronic plantar fasciitis to reduce pain, improve foot functional score, and decrease plantar fascia thickness at short-term follow-up. Further studies in larger populations are needed to identify the optimal treatment regimen including dextrose concentration, volume, injection site, injection technique, and the number of injections required. The long-term effects of these treatments also require further examination. © 2022 American Academy of Physical Medicine and Rehabilitation.
