The goal of this study is to objectify the postoperative pain level, the use of opiates and postoperative nausea and vomiting after adding the adductor canal block to the standard pain regiment after anterior cruciate ligament surgery
Patients scheduled for anterior cruciate ligament surgery will be randomized in an intervention and control group following informed consent. Before surgery, patients will receive an adductor canal bock with Levobupivacaine (intervention group) or 0.9% saline (control group). Following surgery, pain intensity, analgesic consumption and pain satisfaction will be recorded bij patients in a diary for 48 hours.

Postoperative pain level
Using Numerical Rating Scales for pain from 1 to 10, 1 is no pain, 10 is the worst pain you can imagine

Opiate use
postoperative use of opiates (Morphine equivalent dose (mg))

Time frame: Within first 48 hours after surgery
Block result
If there's any loss of motor function (no quadriceps paresis, partial quadriceps paresis, complete quadriceps paresis.) using bromage score
Time frame: within first 24 hours after surgery
Patient satisfaction
Using Numerical Rating Scales from 1 to 10, 1 is not satisfied at all, 10 is completely satisfied
