Effect of Continuous Adductor Canal Block Versus Continuous Adductor Canal Block With Additional Infiltration Between The Popliteal Artery and Capsule of The Knee (IPACK) After Arthroscopic Knee Surgeries

This study is comparing two nerve block techniques used for pain control after knee surgery — a standard adductor canal block (numbing the nerve near the inner thigh) versus the same block combined with an additional injection behind the knee (called IPACK) — to see which provides better pain relief. **You may be eligible if...** - You are between 21 and 65 years old - You are scheduled for elective knee surgery to repair the ACL or PCL ligaments - You are in generally good health (ASA Class I or II) - You received spinal anesthesia successfully **You may NOT be eligible if...** - You declined to give written consent - You have allergies to the study medications - You have a clotting disorder or local infection that prevents nerve blocks - You have multiple traumatic injuries to the leg - You have a BMI over 35 Talk to your doctor to see if this trial is right for you.
