Femoral stem subsidence in cementless total hip arthroplasty: a retrospective single-centre study

ConclusionsIn the present study, stem subsidence was significantly higher in the collarless group compared to collared stems. No anatomical parameter (CFI and CFR) could be identified as risk factor for subsidence. Neither age nor BMI influenced subsidence in this cohort. Still, subgroup analysis indicated a sex-dependent role of BMI. Prospective studies of large cohorts should address the problem of subsidence in the future.Level of evidenceRetrospective therapeutic study, Level IV.
