Sprain or tear of the ACL is one of the most common knee injury specially for athletes who are playing soccer, football and basketball. Cruciate ligaments are found inside our knee joint. They cross each other to form an "X" with the Anterior cruciate in front and the posterior cruciate ligament in back. These ligaments control the back and forth motion of our knees. The anterior cruciate ligament runs diagonally in the middle of the knee which prevents the tibia from sliding out in front of the femur, as well as providing rotational stability to the knee.
Possible cause of injury:
1. Changing direction rapidly.
2. Stopping suddenly.
3. Slowing down while running.
4. Landing from a jump incorrectly.
5. Direct contact or collision.
1. Pain and swelling.
2. Range of motion loss.
3. Joint tenderness.
1. Physical examination.
2. MRI or X-ray imaging.
1. Nonsurgical: Recommended for elderly or have a very low activity level.
Bracing and physical therapy.
2. Surgical: Recommended for athletes.
Rebuilding the ligament. Most ACL tears cannot be sutured back together. The ligament must be reconstructed. It will be replaced with a tissue graft. Often, they are taken from the patellar or hamstring tendons at the back of the thigh are common source of grafts. Sometimes a quadriceps tendon, which runs from the kneecap into the thigh is used. Finally, cadaver graft (allograft) can be used. Because the regrowth takes time, it may be six months or more before an athlete can return to sports after surgery.
Rehabilitation: Rehabilitation plays a vital role in getting back to patient's daily activities. A physical therapy program will help them regain knee strength and motion.
