Minor arthroscopic knee surgery including ACL-reconstruction (hamstrins graft), High pain responders, Adductore Canal Block, Analgesics, Ultrasound guided nerve block

Brief summary

The investigators want to explore the analgesic effect of Adductor Canal Blockade (a peripheral nerve block) in high pain responding patients after arthroscopic knee surgery. The investigators hypothesize that the nerve block will have an abrupt analgesic effect.
