When an ACL Injury occurs, there will be a significant amount of swelling within six hours of the injury happening. The swelling may also continue to increase for the next two days, before it eventually begins to subside. When your physician examines your knee to diagnose the injury, he/she will compare the injured knee to the non-injured knee. Pressure will be applied in different directions to the knee to see which parts stay in their proper position and if there is any restricted movement. If the swelling makes it too difficult to diagnose the tear, your physician may need to run further tests like x-rays, MRI’s, or arthroscopy.Next
