Common Sports Injury- Torn ACL
What is the ACL?
How Do ACL Tears Happen?
Most ACL tears occur as a result of twisting, hyperextending the leg, or pivoting (all common moves in sports, especially football, basketball, soccer, tennis and skiing.) ACL injury often occurs as a non-contact injury resulting in strains and tears.
Women experience ACL tears more often than men, possibly due to estrogen levels making their joints looser. Therefore, younger women and girls are at greater risk for ACL tears. Also, anatomy and muscle function of the knee is different in women than in men, resulting in a tendency for women to have more knee injuries.

- A very sudden and intense onset of pain
- Lots of obvious swelling in the affected knee within the first five to six hours
