Experimental: Levobupivacaine infiltration
Patients will receive spinal anaesthesia with intrathecal bupivacaine, and will receive peri- and intraarticular surgical site infiltration during surgery and before wound closure with a solution of levobupivacaine 0.5% 2mg/kg body weight with epinephrine made up to a volume of 1.5ml/kg with saline. A catheter will be placed by the surgeon before closure and this will be left in situ in the wound. The catheter will be sited under the fascia lata exiting antero-superior to the incision. A bacterial filter will be attached and it will be connected to an elastomeric pump which will deliver a continuous infusion of levobupivacaine 0.25% at 4ml/hr commencing 6 hours postoperatively and continuing for 24 hours.

A catheter will be placed by the surgeon before closure under the sterile surgical conditions and this will be left in situ in the wound. An elastomeric pump will deliver a continuous infusion of levobupivacaine 0.25% at 4ml/hr commencing 6 hours postoperatively and continuing for 24 hours.
Patients will receive spinal anaesthesia with intrathecal bupivacaine 0.5% (17.5 mg if greater than 70 kg and 15 mg if less than 70 kg) and preservative-free morphine (0.2 mg).
Drug: Intrathecal morphine
