You may experience a loud, painful pop when the ligament is first injured, followed by swelling of the
knee. The pain and swelling of an ACL
injury can last for several weeks. Short-term treatment can relieve the pain and inflammation, but it takes months for an ACL injury to heal completely.
Initial treatment for an ACL injury aims to reduce pain and swelling in the knee, regain normal joint movement and strengthen the muscles around the knee.
