Adductor Canal Block Combined With IPACK vs Genicular Nerves Block in Knee Arthroscopy

Not Applicable
Conditions
Arthroscopy
Genicular Nerves Block
Interventions
Biological: Spinal anesthesia and ultrasound-guided Genicular nerves block
Biological: Ultrasound-guided Adductor Canal block (ACB) technique with infiltration of the interspace between popliteal artery and the capsule of posterior knee block ('PACK)
Procedure: Spinal anesthesia only
Registration Number
NCT05269095
Lead Sponsor
Tanta University
Brief Summary

This prospective randomized controlled study is designed to investigate the postoperative analgesic effect of adductor canal block (ACB) combined with infiltration of the interspace between the popliteal artery and the capsule of posterior knee (IPACK) block compared to genicular nerves block in patients undergoing knee arthroscopy.

Detailed Description

Maintaining patient safety, ensuring best patient outcomes, and optimal pain relief post-operatively are of utmost concern for anesthesia providers. Adequate pain relief attenuates stress responses and long-term chronic pain complications while contributing to improved postoperative outcomes.

Knee arthroscopy is a very common procedure and very often is performed as day-case surgery. Ambulatory arthroscopic surgery of the knee is preferred by the majority of properly selected and well-informed patients. It has been reported that a significant number of patients have moderate to severe pain 24 hours after ambulatory surgery in general and knee arthroscopy in particular and pain affects the patient's activity level and satisfaction. Adductor canal block (ACB) is a popular peripheral nerve block that has been shown to decrease the pain significantly and decrease opioid consumption with minimal effect on quadriceps function. It provides analgesia to the peri-articular and intra-articular aspects of the knee joint but doesn't relieve posterior knee pain which is moderate to severe in intensity.
