Objective: Plantar fasciitis is a common degenerative condition causing chronic heel pain and functional limitation. Corticosteroid injections are widely used but carry potential adverse effects, whereas ozone therapy has emerged as an alternative with anti-inflammatory and regenerative properties.The aim of this study is to compare the efficacy of ultrasound-guided corticosteroid and ozone injections on pain, function, and quality of life in chronic plantar fasciitis.Methods: This retrospective cohort study included 59 patients unresponsive to conservative treatment.
Patients received either a single corticosteroid injection (Group S, n=30) or three weekly ozone injections (Group O, n=29). Outcomes were assessed using the Numerical Rating Scale (NRS), Foot Function Index (FFI), and Short Form-12 (SF-12) at baseline, 1 month, and 3 months. Treatment response was defined as ≥50% reduction in NRS.Results: Both groups showed significant improvement over time (p
