Length of hospital stay after knee or hip arthroplasty
Surgeons, blinded to the group allocation, are the postoperative care providers who decide the length of hospital stay.
Time frame: Real length of hospital stay expressed as number of day (maximum 60 days)
Troponin value
Time frame: Postoperative Day 1 and Day 3
Creatinine value
Time frame: Postoperative Day 1 and Day 3
Arterial Lactate
Time frame: 1 hour after end of surgery
Postoperative cardiac complications
Time frame: Participants will be followed for the duration of hospital stay, an expected average of 1 week, until postoperative day 60
Theorical length of hospital stay after knee or hip arthroplasty
Evaluation twice per day starting day 3 until up day 60. A check list was used by an independant investigator to define the theorical date of end hospitalisation, from day 3 until day 60
Time frame: Theorical length of hospital stay expressed as number of day (maximum 60 days)
