This randomized, single surgeon, placebo controlled, double blind study will be conducted in order to investigate whether or not peri-operative high doses of intravenous glucocorticoids improve short-term functional outcome after direct anterior total hip arthroplasty. So far, it has been proven that high dose glucocorticoids reduce immediate post-operative pain and nausea, but no data exists on functional outcome during the first 6 weeks. Our hypothesis is that patients in the intervention group will follow a so-called "get ahead, stay ahead" principle and that glucocorticoids can be considered an important tool (adjuvant treatment) in the enhanced recovery pathway after THA with significant socio-economic implications.


Patients listed for a direct anterior total hip arthroplasty by a single surgeon will be recruited for this study and allocated to one of two groups:

  1. intervention group: 25 grams of iv dexamethasone at induction followed by 10 mg of iv dexamethasone 12 hours later
  2. control group: 5 grams of iv dexamethasone at induction followed by placebo 12 hours later Both patients and surgeons will be blinded. Primary outcome measure will be number of steps during the first 6 weeks as measured by a pedometer. Secondary outcome measures will be side effects, complications, Patient Reported Outcome Measures, pain, nausea, stiffness, achievement of clinical milestones and use of analgesia/anti-emetics. This data will be collected using a tailor made application for a smartphone or tablet and data collecting will start one week before surgery until 6 weeks after surgery.

Based on a power analysis both groups will consist of 35 patients each.
