Abstract: Although the classical treatments listed in the guidelines for osteoarthritis are widely used,

the majority of patients do not fully recover from their pain. It is a fact that new treatment methods

are needed both to relieve pain and restore deteriorated joint function. No study has been found

to date that evaluated the efficacy of ESWT in hip OA. This pilot trial is the first in the literature to

investigate the comparative effects of the two ESWT types (f-ESWT and r-ESWT) in the treatment

of hip OA. Briefly, 148 patients were randomly distributed into the three ESWT groups: focused

(f-ESWT), radial (r-ESWT), and sham (s-ESWT). Patients were assessed with the Visual Analog Scale

(VAS) andWestern Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores just

before the treatment (0 week), just after the treatment (4th week), and 1 month after completion of

the treatment (8th week). VAS and all WOMAC scores were significantly reduced at follow-up points

(4th and 8th weeks) in both the f-ESWT and r-ESWT groups compared with baseline (0 week) (for all,

p < 0.001). Statistical comparisons between the f-ESWT and r-ESWT groups showed that f-ESWT was

superior to r-ESWT for the decrease in VAS and WOMAC scores from baseline to the 4th and 8th

weeks (p < 0.001 or p < 0.002). Both r-ESWT and f-ESWT were found to have significant treatment

efficacy compared with s-ESWT. However, f-ESWT produced a superior improvement in follow-up

parameters compared to r-ESWT.
