Objectives Despite growing evidence and specific guidelines, people with knee and hip osteoarthritis often do not receive appropriate care. This review aims to identify healthcare utilisation and its predictors to optimise existing services and identify unmet needs across different healthcare systems using Andersen’s Healthcare Utilisation Model as a reference.Design We conducted a scoping review and included studies published between 2010 and 2023 that assessed the healthcare utilisation in people with osteoarthritis. We examined general practitioner and orthopaedist consultations, physiotherapy, medication, hospitalisation and emergency department visits.Data sources PubMed, Livivo, Cochrane Library, CINAHL Complete and Web of Science were searched from January 2010 until November 2023. An updated literature search was conducted in December 2025.Data extraction and synthesis We analysed the included studies by means of thematic analysis and descriptive representation of quantitative data.Results The literature search identified 4228 articles, of which 2380 articles were included in the title/abstract screening after excluding duplicates. After the full-text screening of 97 articles, we included 39 (n=4 233 566) publications for data extraction and data synthesis. Most studies were conducted in the USA, Australia, Germany and the UK—few from Asia, Middle and South America and other European countries. Utilised healthcare services are general practitioner consultations (mean use: 43% of participants, n=6), opioid (36%, n=8) and non-steroidal anti-inflammatory drug use (42%, n=7), emergency department visits (27%, n=3), orthopaedic surgeon consultations (26%, n=4), total joint replacement surgery (26%, n=3), physiotherapy (14%, n=8), hospitalisation (11%, n=7) and psychotherapy (6%, n=2). Among predisposing characteristics, older age, female gender, ethnicity, high socioeconomic status, social support and fear of certain treatment options were related to higher healthcare utilisation. In those, gender (n=8 studies) and age (n=6 studies) were primarily discussed. Regarding enabling and need factors, increased healthcare utilisation is associated with urban residence and being insured as well as having pain and comorbidities.Conclusions Results vary between countries. Against the background of existing guidelines, there is a need for promoting the utilisation of non-surgical and non-pharmacological treatments, such as physiotherapy, which have proven to be effective. Special attention should be given to predictors when promoting appropriate healthcare utilisation. Addressing the identified predictors associated with healthcare utilisation may lead to more appropriate osteoarthritis care. Further research is needed to address healthcare stakeholders’ (physiotherapists, insurers, patients and practitioners) needs and roles in the process.Trial registration number Protocol registration on PROSPERO (CRD42023475803).
