Injury of Anterior Cruciate Ligament

Brief summary

The aim of this prospective, randomized , blinded study is to compare two different infusion techniques (continuous VS intermittent automatic bolus) to assess the effects of postoperative analgesia after Day-Case anterior cruciate ligament (ACL) reconstruction.

Interventions

PROCEDUREContinuous Infusion of ropivacaine 0.2%

Postoperative continuous infusion of Ropivacaine 0,2% at 6 ml/h and 4 ml PCA bolus, lockout 20 minutes via electronic infusion pump (Micrel device, Greece).

PROCEDUREAutomatic Intermittent Bolus of ropivacaine 0.2%

Postoperative Automatic Intermittent Bolus of 6 ml Ropivacaine 0,2% every hour and 4 ml PCA bolus, lockout 20 minutes via electronic infusion pump (Micrel device, Greece).
