The ACL is located in the center of the knee along with the posterior cruciate ligament (PCL). This Paper. Advantage is that it has no dependence on friction between the graft and tunnel wall. The modern high speed vehicular trauma and sporting life style has led to increased ligament injuries of the knee. About the Anterior Cruciate Ligament (ACL) There are four main ligaments that stabilize the knee. This is a grade 1 or grade 2 AC joint injury, and a quick and full recovery can be expected in a matter of days to weeks. 2021 Sports Rehabilitation Course.

PRP administered with the help of a sutured and compressed Gelfoam; 5 mL PRP was added homogeneously so as to completely cover the graft. The anterolateral ligament (ALL) and capsule of the knee are anatomical structures involved in rotational stability and pivot-shift control. Suspensory fixation of anterior cruciate ligament (ACL) graft to the femur is a popular technique employed in ACL reconstruction (ACLR). So no issues there. 1.
