Final answer:
The angle at which an ACL graft is tensioned can range from 20 to 40 degrees of knee flexion. For a PCL graft, the tensioning angle is typically 90 degrees of knee flexion.
Step-by-step explanation:
When tensioning an ACL graft, the angle at which the graft is tensioned can vary depending on factors such as the individual patient's anatomy and the surgeon's preference. However, a common range for tensioning an ACL graft is between 20 and 40 degrees of knee flexion.
For a PCL graft, the tensioning angle is typically around 90 degrees of knee flexion.
It's important to note that the specific tensioning angle may be adjusted by the surgeon during the procedure to achieve the desired stability and functionality of the reconstructed ligament.
