Abstract
Background: Impaired hip strength may underlie abnormal movement patterns, suggesting that diminished hip strength may increase the risk of ACL injury and re injury after anterior cruciate ligament reconstruction.
Aim of Study: To investigate the effect of strengthening of hip extensors and ankle plantar flexors in early Anterior Cruciate Ligament reconstruction on knee effusion, knee function, hip, knee and ankle muscles strength.
Methods: The study was conducted on 30 male patients referred from the orthopedic surgeon with early post operative Anteior Cruciate Ligament reconstruction by hamstring graft or patellar tendon graft after acute injuries, their age range from 18-40 years and were randomly assigned into two groups. Group A: Consisted of fifteen patients who had received open kinetic chain strengthening exercises for hip extensors and ankle plantar flexors in addition to the traditional accelerated program. Group B: Consisted of fifteen patients who had received the traditional accelerated program for 6 weeks (three sessions per week), effusion grading scale for effusion to assess effusion, handheld dynamometer to assess muscle power, Westen Ontario and MACmaster universities score and Time Up and Go test for functional assessment.
Results: There was no significant difference between both groups for, hip extensors force and (TUG at 3 weeks). There was no significant difference between both groups for knee extensors torque between base line and 3 weeks and the same for plantar flexors force and WOMAC at 3 weeks. There was significant difference between both groups for knee extensors torque between 3 and 6 weeks, WOMAC at 6 weeks, TUG at 6 weeks and plantar flexors force between 3 and 6 weeks.
Conclusion: Adding strengthening exercises of hip exten-sors and plantar flexors to the traditional accelerated protocol added more beneficial outcomes in relation to function after 6 weeks.
