study the effect of music therapy in pre-operative and post operative period and measure the out come by the visual analog scale (pain score) and analgesic drug use such as morphine and the anxiety score

Objectives Primary Objective : To study and compare pain symptoms between the group of patients after undergoing Anterior Cruciate Ligament reconstruction surgery and the control group, using pain relievers along with listening to music perioperatively and postoperatively.

Secondary Objective : To study and compare the levels of anxiety and changes in the circulatory system among patients after undergoing Anterior Cruciate Ligament reconstruction surgery and the control group, from listening to music perioperatively and postoperatively.

Research Questions Does listening to music perioperatively and postoperatively during Arthroscopic Anterior Cruciate Ligament reconstruction surgery help reduce postoperative pain?

Hypothesis The group of patients who listened to music perioperatively and postoperatively during Arthroscopic Anterior Cruciate Ligament reconstruction surgery will experience reduced postoperative pain compared to the group that did not listen to music.

Methodology Randomized Controlled Trial (RCT) Sample Size Calculation The calculation of the sample size for testing two independent means, using the method referenced from the study by Xavier C. Simcock and colleagues on "Intraoperative Music Reduces Perceived Pain After Total Knee Arthroplasty total 38 and add 20% for dropout rate
