Takeaway

  • Osteoarthritis (OA) was positively associated with the incidence of fractures.

  • This association between OA and fracture was significant in all sex, age and OA joint site subgroups.

Why this matters

  • Findings highlight the urgent need for intervention to reduce the risk of fracture in adults with OA.

  • Future studies are warranted to gain a better insight into the mediators involved in the association between OA and fracture.

Study design

  • A retrospective cohort study of 129,348 patients who had received an initial diagnosis of OA (aged, ≥18 years) in one of 256 general practices in the UK between 1997 and 2016 (index date).

  • Patients with OA were matched (1:1) to those without OA by sex, age, index year, diabetes, dementia, corticosteroid therapy and practice.

  • All patients were followed from the index date for up to 10 years for incidence of any fracture.

  • Funding: None.

Key results

  • After 10 years of follow-up, 12.1% of participants with OA and 7.7% of those without OA had suffered ≥1 fracture (log-rank P<.001).

  • A positive and significant association was seen between OA and fracture (HR, 1.55; 95% CI, 1.50-1.60; P<.001). 

  • The association between OA and fracture was significant in all sex, age and OA joint site subgroups (HR; 95% CI):

    • men (1.58; 1.48-1.69);

    • women (1.55; 1.49-1.61);

    • age 18-50 years (1.62; 1.48-1.78);

    • age 51-60 years (1.40; 1.30-1.51);

    • age 61-70 years (1.42; 1.32-1.53);

    • age 71-80 years (1.56; 1.45-1.67);

    • age >80 years (1.61; 1.47-1.75);

    • polyarthritis group (1.60; 1.41-1.81);

    • hip OA group (1.40; 1.23-1.60);

    • knee OA group (1.36; 1.16-1.59); and

    • other and unspecified OA group (1.57; 1.51-1.63).

Limitations

  • Retrospective design.
