The anterior cruciate ligament (ACL), it is a dense connective tissue band originating from the medial wall of the lateral femoral condyl and inserts into the middle of the intercondylar region on the tibia. It is regarded as a crucial component in the knee joint because it resists anterior tibial translation and rotational load. Young athletes who participate in sports that demand turning, decelerating, and jumping are at high risk for ACL injury. People who participate in Pivoting sports are likely to have them (e.g. football, basketball, netball, soccer, European team handball, gymnastics, downhill skiing). Environmental (e.g., high friction between shoes and the playing surface) and anatomical variables are also risk factors for ACL injury (e.g. narrow femoral intercondylar notch). Knee instability causes a reduction in activity, which can result in a decrease in knee-related quality of life. ACL injury risk factors have been classified as either internal or external to a person. Type of competition, footwear and surface, and environmental conditions are all external risk factors. Anatomical, hormonal, and neuromuscular risk factors are all internal risk factors.
 Aim and Objective: to compare the efficacy of Myofacial Release Technique versus Positional Release Therapy on range of motion post ACL reconstruction.
 Methodology: In this study total 45 patients with post ACL reconstruction will be divided into two groups, one group will receive muscle energy technique and other group will received positional release therapy. The treatment will be given for 5 sessions per week for six weeks. The assessment will be done at day one of treatment at the end of treatment at the end of first week and at the end of six week.
 Discussion: This study will find the better technique for improving Range of motion Post ACL reconstruction.
 Conclusion: Conclusion of the study will be drawn after the statistical analysis of the data gathered from the individuals enrolled in the study.
