Brief Summary:

Opioid-free anesthesia (ATO) is a multimodal anaesthesia combining different analgesic and anesthetic modalities thus excluding opiates as an intraoperative. Recent studies have found a benefit from the ATO on postoperative rehabilitation and reduced length of hospitalization.

Periarticular infiltration with a local anesthetic is one of the measures proposed in OFA during the PTH.

PTH remains a painful procedure and the occurrence of morphinic-related side effects in sometimes elderly patients is often observed.

The main objective of this study is to assess the feasibility of ATO in anterior hip replacement under general anesthesia with the primary endpoint of morphine consumption measured 24 hours after surgery.
