Association of socioeconomic status on return to work following primary total hip arthroplasty: a Danish population-based cohort study on 9,431 patients from 2008-2018.

Background And Purpose:  Return to work (RTW) following primary total hip arthroplasty (THA) is important for patients and society. We aimed to investigate the association between markers of socioeconomic status (SES) and RTW after primary THA, and whether the association is influenced by sex, age, and comorbidity.

Methods:  Using Danish population-based registries we included 9,431 patients aged 18 to 59 years, undergoing primary THA for osteoarthritis from 2008-2018.

Minimal important change in the Hip Disability and Osteoarthritis Outcome Score and the European Quality of Life 5 Dimensions in adults with hip osteoarthritis after 12 weeks of exercise.

Background: Minimal important change (MIC) is the smallest change that can be considered important. In hip osteoarthritis (OA) several measurement instruments are recommended but lack MIC estimates.

Objectives: The objective was to estimate the MIC after supervised group-based exercise for the following measurement instruments; Hip Disability and Osteoarthritis Outcome Score (HOOS), European Quality of Life 5 Dimensions (EQ-5D-5L), 30-s Chair Stand Test, 40-m Fast-paced Walk Test, 9-step Stair Climb Test, Nottingham Leg Extension Power Rig, and unilateral One-Repetition-Maximum Leg Press.
