Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The purpose of the study is to scientifically determine the functional effectiveness of anatomy sparing surgery in total hip arthroplasty in comparison with traditional open surgery, measured by the Harris Hip Score. | — |
Secondary
| Measure | Time frame |
|---|---|
| Number of virtual admission days. Virtual is defined as the number of days until the patient is ready for discharge in the opinion of the surgeon and the patient. Any additional days due to logistic circumstances are not included in this main objective. Virtual discharge criteria are: -function, measured in: -50m walking, -walking 1 stairs, -getting in and out of bed-Pain (VAS icm function)-Wound assessment: incl. effusion + aspect -The Western Ontario and McMaster Universities Osteoarthritis Index -Visual Analogue Scale (VAS) is used to measure severity of pain during different activities. (Corianne kijkt hoe pijnmedicatie en VAS-score te combineren) Use of analgesics. -The SF-36 (pre-operative and at 1 year follow-up) -Patient satisfaction (Corianne: zijn verschillende mogelijkheden) -Total operation time. -Number and kind of complications (incl wound infection, wound haematoma, dislocations (main objective gebaseerd op funtionele uitkomst, compl dus geen effect!) -Need for blood transfusion. -Wound aspect during treatment period. | — |
