Adductor Canal Block and Arthroscopic Knee Surgery, High Pain Responders

Phase 4

Completed

• Conditions: Arthroscopic Knee Surgery
• Interventions: Procedure: Intervention group, block no. 1 - Ropivacain

• Registration Number: NCT02001662
• Lead Sponsor: Glostrup University Hospital, Copenhagen

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.
