At the moment you injure your ACL, you may feel a tearing within your knee or hear a "popping" noise. Your knee then may give way.
Most people cannot continue with their sporting activities immediately after an ACL injury.
Other common symptoms include:
- Pain and swelling.
Within 24 hours, your knee will swell. If ignored, the swelling and pain may get better on its own. However, if you attempt to return to sports, your knee will probably be unstable and you risk causing further damage to the cushioning cartilage (meniscus) of your knee.
- Loss of full range of motion
- Tenderness along the joint line
- Discomfort while walking
