O29 Returning to, and staying in, work after total hip arthroplasty

Abstract Background/Aims Total hip arthroplasty is increasingly offered at younger ages whilst simultaneously people are being encouraged to work to older ages. Ultimately, more people will expect to need to return to work post-THA. We explored the rates of return to work and the trajectories of remaining in work post-THA, with particular attention to the physical demands of the post-operative job. Methods Patients from the Geneva Hip Arthroplasty Registry and the Clinical Outcomes of Arthroplasty (COASt) study who underwent unilateral THA at least 5 years previously were identified. Participants were eligible if they were 4 hours/day (HR: 3.37, 95%CI 1.44-7.86), kneeling/squatting (HR: 95%CI 3.67, 1.61-8.40) and carrying/lifting> 10 kg (HR: 5.68, 95%CI 2.37-13.62) . Mutually adjusted models showed that the effect of lifting/carrying weights in excess of 10 kg remained statistically significant (p < 0.01). Conclusion These findings suggest that some jobs may
