An anterior cruciate ligament injury occurs when the anterior cruciate ligament (ACL) is either stretched, partially torn, or completely torn. [1] The most common injury is a complete tear. [1] Symptoms include pain, an audible cracking sound during injury, instability of the knee, and joint swelling. [1]
Most ACL tears are a result of a non-contact mechanism such as a sudden change in a direction causing the knee to rotate inward. As the knee rotates inward, additional strain is placed on the ACL, since the femur and tibia, which are the two bones that articulate together forming the knee joint, move in opposite directions, causing the ACL to tear.
Injury. Anterior cruciate ligament tear seen on MRI. An anterior cruciate ligament injury results from excess tension on the ligament. This can come from a sudden stop or twisting motion of the knee. A few initial symptoms include swelling, knee instability, and pain. A popping sound or sensation may or may not be heard when the ACL first tears.
The crutches can be discontinued when the patient can walk without limping. Quadriceps strengthening exercises are allowed, but no isolated hamstring exercises should be attempted for 6 – 10 weeks following the injury. If after 10 weeks, pain or instability continue, the patient should be reevaluated for surgical treatment. [5] [22] [30]
Anterior Cruciate Ligament damage is a very common injury, especially among athletes. Anterior Cruciate Ligament Reconstruction (ACL) surgery is a common intervention. 1 in every 3,000 American ruptures their ACL and between 100,000 and 300,000 reconstruction surgeries will be performed each year in the United States.
The injury needed time, but “time,” she later wrote, “is what I don’t have.” She was racing against it. She attacked pool workouts and gym rehab, far sooner than most doctors would have ...

Proof of muscle strengthening without damage: One recurring problem in ACL rehabilitation is improving muscle strength of the quadriceps without re-injury. Early, high-force eccentric training can be used to increase muscle strength and volume without damage to the ACL graft, surrounding soft tissue, and the articular cartilage. [ 8 ]
