-According to Hewett et al. Understanding and Preventing ACL Injuries: Current Biomechanics and Epidemiologic Consideration. There are several common biomechanical characteristics and motor behavioral associated with non-contact ACL injuries. -Inward or valgus collapse of the knee places excessive forces on the passive structures of the knee which include MCL meniscus and ACL.  Persistent valgus stress...Read More

In healthy adults, the ACL is able to absorb approximately 2000 N of force which equates to approximately 450 pounds of direct force.  Although there are dramatic variations depending on the patient’s age health and type of graph, an ACL graph should eventually be able to resist similar forces.  However, following an ACL reconstruction, the...Read More

The basics of the human muscle anatomy (muscle innervation, insertion/origin, action) is critical when studying for any physical therapy and specifically critical when studying for the OCS exam.  It can be very difficult and challenging as most anatomy texts do not provide quick summaries at a quick glance.  I take no credit for the anatomy...Read More

The graft is significantly weaker following surgery.  Graft protection must be considered as the graft can be almost 90% less stiff than a typical ACL.  As the graft takes to the bone the ACL can absorb more tensile forces.  Early rehab should limit non-weight-bearing exercises under 50 degrees of flexion.  Weight-bearing exercises decrease the load...Read More
