Background: Anterior knee pain syndrome is the most common knee complaint seen in adolescents and young adults. It is might be caused by trigger points in quadriceps muscle. Purpose: The aim of this study was to investigate the effect of manual ischemic compression on quadriceps trigger points on patients suffering from anterior knee pain syndrome. Subjects and Methods: This was a quantitative, clinical exploratory study, thirty suitable participants suffering from anterior knee pain syndrome aging between 25-40 year males and females were randomly allocated into two equal groups, and both groups were screened for quadriceps' trigger points. All participants were assessed before any intervention and after 15 sessions, subjective data was obtained using Kujala Patellofemoral Scoring System for pain and functional level assessment while objective data was obtained using the Pressure algometer to measure the level of Pressure Pain Threshold, group A consisted of 15 participants and considered the experimental group was treated by manual ischemic compression beside the conventional physical therapy program consisted of (hot packs, patellar mobilization, strengthening exercise and activity modification), while group B consisted of 15 participants and considered the control group which treated by the same conventional physical therapy program only. Results: showed that there was no statistical significant difference between outcome data obtained from both groups in Kujala patellofemoral scoring system (P-Value >0.05) and in algometric readings for pressure pain threshold (P-Value >0.05). Conclusion: There was no significant effect of manual ischemic compression on quadriceps trigger points in anterior knee pain syndrome
