This study aims to determine whether ESWT (extracorporeal shock wave therapy) affects ONFH (osteonecrosis of femoral head) in clinical outcomes and radiography outcomes. Two authors independently search the papers on the treatment of femoral head necrosis with extracorporeal shock wave in CNKI (China National Knowledge Infrastructure), VIP (China Science and Technology Journal Database), CSPD (China Science Periodical Database), Pubmed, Embase, and Springer databases. Search period from the inception dates to 2 June 2020 and have no limitations in language; two authors independently conducted a quality evaluation and data extraction for included studies and performed a meta-analysis with data extracted and calculate by using RevMan5. Registration number: CRD42020213580. Nine articles with 409 patients are included in this meta-analysis. The pooled results of HHS (Harris hip score) in eight studies with 337 hips show that ESWT achieves higher Harris scores compared to before treatment (MD = −19.95; 95% CI: −26.27, −13.64) and the difference is statistically significant (p
