This study is a literature review comparing and contrasting the advantages of closed kinetic chain exercise over open kinetic chain exercise. It is the purpose of this study to show that open kinetic chain exercise may not be the safest or the most functional way to rehabilitate the lower extremity. It is also the purpose to show the specific advantages of using closed kinetic chain exercise over open kinetic chain exercise to protect the integrity of the ACL deficient or reconstructed knee by decreasing anterior shear forces, increasing joint compression, increasing joint proprioception, increasing muscular joint compression, and increasing the functional aspect of the patients rehab.

The current literature suggests that closed kinetic chain activities may be a better choice for rehabilitation over open kinetic chain activities. Research shows that there is scientific evidence that closed kinetic chain exercises are safer and more functional than open kinetic chain exercise due to the fact that closed kinetic chain exercises decrease anterior shear forces, increase muscular co-contraction, increase tibiofemoral joint compression, increase joint proprioception, and are a more functional way to rehabilitate an injury.
