Anterior Cruciate Ligament Injury (ACL)
This problem in more common in young athletes. It is also more common in athletes who are female. Some sports that may raise the risk are skiing, snowboarding, soccer, and basketball.
Other things that may raise the risk are:
- Abnormal foot structure
- Poor flexibility and strength
- Slow reaction time
- Strength, flexibility, and coordination differences between the right and left leg
- Playing on uneven or wet surfaces
- Wearing shoes that are not right for the playing surface
The ACL does not heal on its own. The first steps will be to ease pain and swelling. This can be done with rest, ice, medicine, and elevating the leg.
Active people under 35 years of age may need surgery. It will remake the ACL with tissue from other areas of the body or from donor tissue.
Older adults who are not as active may not need surgery, especially if the knee is stable. Exercises may be given to strengthen the muscles around the knee.
