Background summary
Rupture of the Anterior Cruciate Ligament (ACL) is a common injury leading to increasing numbers of ACL reconstruction (ACLR) around the world. Return to play (RTP) is becoming a more and more important outcome measure after ACLR. Recent reviews have shown that a mere 55% of patients after ACLR can return to their pre-injury level of sports. It is hypothesized that ACLR is incapable of reducing excessive tibial rotation, which leads to poor outcomes in respect of RTP.
Objective: The main study objective will be to determine whether there is an excessive tibial rotation in ACL deficiency and how this develops over time.
As instability mostly occurs during sports, it is essential to test subjects in these circumstances. In order to test in high-demanding activities, several tests have been developed such as the one-legged forward hop test and the side step.
These tests have been validated in healthy subjects using a skin-marker based Motion Capture System (VICON). With VICON, movement of the tibia in relation to the femur can be objectified in a three-dimensional matter. VICON uses 8 infrared cameras to detect reflective markers in an area. These markers can be attached to bony landmarks. In this manner VICON can analyse movement of the tibia relative to the femur.
Study objective
There is a difference in the range of tibial rotation between ACL ruptured knees and ACL intact knees.
