We treat Total Hip Arthroplasties and Total Knee Arthroplasties on our ortho ward and we have a provincial protocol that we follow (exercises and mobilisation 2x/day). If the person has their surgery on the Friday, they still get the 2x/day treatment over the weekend. Therefore they're deemed higher priority.
New assessments for crutch-walkers are also high priority for PT intervention on the weekend. Especially if it means they can be discharged home the day after they get an ORIF of their ankle.
