| Main Objective: We will perform a double blind randomised comparison of oral paracetamol versus intravenous paracetamol (Perfalgan) in patients undergoing knee arthroscopy in a day surgery setting. The main purpose of the trial will be to compare the analgesic effects of oral and intravenous paracetamol.;Secondary Objective: To note any side effects of using Perfalgan;Primary end point(s): Postoperative pain assessed by Visual Analogue Scale (VAS) scores and Verbal Rated Scale (VRS) scores during rest and during movement. Rescue analgesia required. | — |
