Abstract:
Patellofemoral pain syndrome (PFPS), as a common source of diffused anterior knee pain in young and active individuals, accounts for 25% of all the knee problems in sports medicine clinic. It is an idiopathic condition characterized by aching pain in the peripatellar area, which is exacerbated by physical activities, such as climbing stairs, squatting, jumping, running and prolonged sitting. Despite its prevalence, the etiology and treatment of this syndrome remain vague and controversial. More recently, studies have focused on hip muscle dysfunction as a possible contributor to patellofemoral pain. Recent studies show that Hip weakness is associated with PFPS especially hip abductors and external rotators. Patients with PFPS could benefit from hip muscle strengthening, since this intervention may reduce excessive hip motion and, as a consequence, excessive patellofemoral joint stress. The main of the study to compare the efficacy between VMO strengthening with Hip strengthening Vs. VMO strengthening alone on pain and function in patients with PFPS.A total of Subjects who matched the inclusion and exclusion criteria were recruited for this study and randomly divided into two groups. Permission was obtained from the hospital authorities. Subjects were explained in detail about the study and written consent form was taken. Demographic data of the subjects was collected and recorded. Pre-participation evaluation form consisted of VAS and AKPS. Pain was assessed by Visual analogue Scale, and Functional Disability by Anterior Knee Pain Scale. The patients were divided into two groups: Experimental group and Control group. Experimental group was given VMO Strengthening exercises along with Hip Strengthening exercises and Control group was given VMO Strengthening exercises alone. After 4 weeks of intervention the subjects were again assessed by VAS and AKPS and values were recorded. All the exercises were performed under guidance and home program was given. Treatment protocol: 3 times a week for 4 weeks. The data obtained were recorded and analyzed. Student t test (two tailed, dependent) has been used to find the significance of study parameters on continuous scale within each group. Student t test (two tailed, independent) has been used to find the significance of study parameters on continuous scale between two groups (Inter group analysis) on metric parameters. The statistical analysis indicated that there was strong statistical significance in VAS and AKPS in both the groups with P value of<0.001**, but in between groups, group A showed suggestive statistical significance with P value of 0.074+ in AKPS score and no statistical significance in VAS score compared to group B
