This is a monocentric, interventional, prospective, comparative, randomized study in 2 parallel groups, single-blind. The study is proposed to the patient during the preoperative anesthetic consultation. The patient and the people carrying out the functional assessments (physiotherapists) will be blinded to the analgesia received, unlike the investigator.~Patients will be included by an anesthesiologist during the preoperative anesthetic consultation. After the Accelerated Rehabilitation After Surgery consultation, they will then be operated on (Day 0) and seen up to 5 times post-operatively over a period of 45 days for the purposes of the study: at 24h, 48h, 72h, discharge from hospital and 45 days post operative. Discharge from hospital occurs during follow-up depending on the patient's condition. These visits will coincide with follow-up consultations with the surgeon as part of the usual management.
The purpose of the study is post-operative recovery from prosthetic knee surgery will be assessed by the proportion of patients entering the Accelerated Rehabilitation After Surgery program eligible for discharge from hospital at 2 days according to the following definition: Chung score ≥ 9 with no intravenous (IV) infusion, solid food, transit restored, no signs of infection and Cumulated Ambulation Score D1 ≥ 5 (if discharged on Day 1), Cumulated Ambulation Score Day 2 ≥ 10 (if discharged on Day 2), or Cumulated Ambulation Score Day 3 ≥ 11/18.
