When you can return to work depends on what your work asks of your hip. Many people with seated work return somewhere in the first weeks to months; physically demanding work usually takes longer, sometimes a few months.
Things that make the return easier: starting with shorter days or lighter duties where possible, planning regular changes of position, and keeping your exercise routine alongside work rather than dropping it on busy days.
Discuss timing with your surgical team, and be honest with yourself about how the hip responds in the first weeks back - adjust rather than push through.
