[Purpose] To investigate the relationship between the lateral tibial rotation angle during knee joint flexion and the medial and lateral hamstring muscle thickness ratio during knee joint extension ...

Introduction Rupture of the ACL is an increasing problem in sports medicine. ACL reconstruction (ACL-R) with hamstring autograft is often the preferred treatment. The isokinetic test assesses muscle ...

Background: Many injury prevention and rehabilitation programs aim to train hamstring and quadriceps co-activation to constrain excessive anterior tibial translation and protect the anterior cruciate ...

Background: The reason for the higher incidence of anterior cruciate ligament injury from non-contact mechanisms in female athletes is not known. Stability of the joint from dynamic restraints occurs ...

The purpose of this pilot study was to investigate whether hamstring-quadriceps co-activation altered knee joint motion and limited ACL elongation during a step-up task. Although preliminary, the ...

Combined anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries are the most common type of combined ligamentous injury of the knee. The optimal treatment for these combined ...

The contemporary treatment of hamstring avulsions has been evolving, as more patients are being identified as having persistently symptomatic partial hamstring tears recalcitrant to nonoperative ...
