Background: Knee ligament injuries are among the most common sports lesions. However injuries of anterior cruciate ligament are frequent especially in amateur football who does not realize streching muscular before entering in the field. Purpose: The purpose of this study was to evaluate physical therapy combined with reinforcing exercises post arthroscopy for anterior cruciate ligament Methods: This is a Pilot Randomized Clinical Trial Study. Patients were divided into two groups .In group A patients (n=5) were underwent a protocol with physical therapy combined with reinforcing exercises, while in group B (n=5), patients underwent only physical therapy. Like outcomes measures included visual analogic scale (VAS) and range of motion was measured with a goniometer. Results: In group A values were significant for visual analogue scale VAS with (p value < 0, 05) was compared with group B. While degrees of motion in group A were positive for a relatively shorter period than in group B. Conclusion: In the group A which was applied physical therapy combined with reinforcement exercises were efficient results than in group B that was applied only the physical therapy (TENS) in amateur football sports.
