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.

Patients with successful spinal anesthesia.
Declining to give written informed consent.
History of allergy to the medications used in the study.
Contraindications to regional anesthesia (including coagulopathy and local infection).
Polytrauma patients having lower limb fractures.

Degree of pain
The degree of pain will be assessed using the Visual Analogue Scale (VAS). VAS score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. No pain (0-4 mm), mild pain (5-44 mm), moderate pain (45-74 mm), and severe pain (75-100 mm).
Total Nalbuphine consumption
Rescue analgesia will be given when VAS score ≥ 30 mm, in the form of IV injection of 10 mg Nalbuphine. Followed by reassessment of pain after 10 minutes, a second dose of Nalbuphine will be given if still VAS score ≥ 30 mm.
Straight leg rise
Straight leg rise (SLR) will be recorded.
Range of motion
Range of motion (ROM) will be recorded
Rate of complications
Rate of complications like falling will be recorded
