Details and patient eligibility


Extracorporeal Shock Wave Therapy (ESWT) is a conservative treatment method that has been widely used in musculoskeletal diseases in recent years. Its mechanism is to provide hyperstimulation and vascularity increase with the help of acoustic waves focused on a specific area, thus accelerating healing and reducing pain. This method, which is frequently used in plantar fasciitis, is frequently applied to patients whose symptoms persist despite first-line treatment strategies. Ozone injections have been frequently used in musculoskeletal disorders in recent years and are mainly used in osteoarthritis, osteomyelitis, tendon, fascia and ligament injuries, vertebra and disc pathologies and neuropathic pain. Analgesic effect on musculoskeletal system (release of endorphins, activation of antinociceptive system, reduction of edema) anti-inflammatory effect (regulation of cytokine release, reduction of superoxide radicals, modulation of prostaglandin), regulation of local oxygenation and circulation, tissue repair (neutralization of preteolytic enzymes, fibroblast proliferation) and has an antimicrobial effect. Although it is also used in the treatment of plantar fasciitis, there are limited articles on this subject in the literature. In our study, it was aimed to compare the effectiveness of ESWT and ozone injection therapy, which are two treatment strategies with regenerative action mechanisms, in patients with resistant plantar fasciitis.
