Effectiveness of ultrasound-guided hip injections on pain and functioning in patients with hip osteoarthritis: A systematic review.
Systematic Review
Osteoarthritis is the most common form of arthritis, causing pain, functional disability, and a reduction in terms of quality of life. Minimally invasive treatments like intra-articular hip injections are a therapeutic option and ultrasound guidance might improve the results of these injections./r/nTo summarize the evidence about the effectiveness of ultrasound-guided hip injections in terms of pain and functioning in patients affected by hip osteoarthritis./r/nA systematic search of the literature was performed on three electronic databases: PubMed, Cochrane and PEDro, using a specific search strategy. We evaluated for inclusion all articles according to the following participants, intervention, comparison, and outcomes (PICO) model: P) Population: human patients affected by hip osteoarthritis; I) Intervention: intra-articular hip injections performed with a ultrasound-guidance; C) Comparator: sham therapy or every other conservative or oral, non-invasive, minimally invasive or surgical technique; O) Outcome measures: pain assessed by Visual Analogue Scale (VAS) or Numerical Rating Scale (NRS); functional outcomes./r/nAt the end of the search, 43 articles were included in the review. Several drugs have been considered in the included studies: hyaluronic acid, platelet-rich plasma, corticosteroids, micro-fragmented adipose tissue, bone marrow concentrates, amniotic suspension allograft./r/nUltrasound-guided injections of hyaluronic acid might be effective on pain relief and functioning in patients affected by hip osteoarthritis. Also, other rehabilitative infiltrative techniques (i.e., corticosteroids and platelet-rich plasma) showed a positive effect in the short-term period.
