Brief summary: Patellofemoral pain syndrome is a condition of misleading diagnosis. It mostly affects individuals with ages between 18-40 years. It is believed that much work has been done on the joint itself in treating the Quadriceps muscles and triggers related to it but now literature is focusing on the segmental involvement, where weakness of the hip abductors and lateral rotators play a major role. Therefore, interventions used for treating this syndrome should include on focusing the hip muscles for trigger point therapy as well as strengthening them in increasing the stability of the hip and pelvis to reduce excessive valgus forces on the knee.

Detailed description: Literature regarding Gluteus Medius trigger point is quite scarce especially in alleviating the pain related to Patellofemoral Pain Syndrome. The management of Patellofemoral Pain Syndrome includes a segmental treatment, giving special focus to the lateral rotators and abductors of the hip especially Gluteus Medius muscle, rather than treating the Patellofemoral Joint itself. It will help in improving the pain of the subjects suffering from this syndrome effectively, and within a shorter duration of time. It will also provide the practicing physiotherapist with an insight for treating such patients with better outcomes. Myofascial Trigger Points of the Gluteus Medius are important contributing factors in the management of Patellofemoral Pain Syndrome which is identified in a single study as per author's knowledge. But the treatment used to release the trigger point of Gluteus Medius in managing this syndrome has not yet been explored. So, this study will compare two well-known treatments in comprehending which one of the two techniques have better effects on the population to be studied. Written consent will be taken from all the study participants. Simple randomization technique will be used through "Randomization Main" software and randomization sheet will be generated. 60 participants with patellofemoral pain syndrome having Gluteus Medius trigger point will be randomly allocated in two equal group.
