The purpose of this study to determine the effects of the addition of isolated hip strengthening exercises to traditional rehabilitation after Anterior cruciate ligament reconstruction (ACLR). Clamshells exercises unique in scene because it mainly focuses on the muscle surrounding the hip whereas the traditional exercises mostly paid attention on quads and hams exercise

In 2020, researcher conducted a randomized controlled clinical trial to determine "Does six-weeks of Hip-focused exercises has the effects on Time to Stabilization after Anterior Cruciate Ligament Reconstruction". The purpose of these study to determine the relationship between muscle strength and time taking to increase the performance of knee. The main findings suggesting that rehabilitation program targets on strengthen the hip muscles in comparison with traditional exercises of knee demonstrate an improvement of knee functions in individual with Anterior cruciate ligament reconstruction (ACLR).

In previous studies there is very less literature regarding determining effects of the clamshells exercises on extension lag after anterior cruciate ligament reconstruction. Therefore there is a dire need to explore the effect of the clamshells exercises on post anterior cruciate ligament reconstruction extension lag. This study aims in the management of pain disability and functional impairment in persons with extension lag with clamshells exercises after ACL reconstruction.
