The haemoglobin (HGB) drop, the transfusion rate, and the LOS were recorded. The postoperative pain during active motion (hip flexion of 45°) was measured using a visual analogue scale (VAS) at 24 h, 72 h, 1 week, 4 weeks, and 3 months after surgery. Functional outcomes, including the Harris hip score (HHS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), were evaluated at 1 week, 4 weeks, 3 months, 6 months, 1 and 2 years after surgery. The length of the scar and the Scar Cosmesis Assessment and Rating (SCAR) scale were assessed at 1 year follow-up
