Causes
MCL injuries are often caused by a direct hit to the outside of the knee. This is common in sports such as:
- Hockey
- Football
- Rugby

While this is usually the result of a sports hit or tackle, it can also result from a fall or car accident.
Sports that involve bending, twisting, and quick changes in direction can also cause MCL injuries. This includes:
- Downhill Skiing
- Soccer
- Basketball

The above are known as acute injuries, meaning they are the result of a one-time incident (trauma) that caused the MCL to become damaged. The MCL can also become damaged due to repetitive movements over time. This is known as a degenerative injury or repetitive strain injury. While acute injuries are common amongst younger, more athletic patients, degeneration is usually seen among patients who are 40+.
