Brief summary: This study aims to evaluate the effect of Continuous Adductor Canal Block only versus adding posterior knee block, known as the Infiltration between the Popliteal Artery and Capsule of the Knee (IPACK) block with Continuous Adductor Canal Block (CACB) after arthroscopic knee surgeries.

Detailed description: Enhanced recovery after arthroscopic knee surgery is gaining popularity in orthopedic surgeries. Motor preservation with adequate analgesia has become the optimal postoperative goal, enabling earlier physical therapy, faster recovery, and early hospital discharge. Spinal anesthesia for knee arthroscopy has favorable outcome effects compared with general anesthesia. The positive physiological effects of the provided sympathetic blockade with less blood loss, increased leg blood flow, and better initial pain relief explain this.

An ideal nerve block that targets the sensory nerves and spares the motor function can facilitate early ambulation and rehabilitation, a major goal for patients undergoing arthroscopic knee surgery.

A novel technique for posterior knee block, known as the infiltration between the popliteal artery and capsule of the knee (IPACK) block combined with continuous adductor canal block (CACB) would reduce opioid requirements.
