Recognise common injury symptoms and understand the assessment and recovery process.
What is the ACL?
The anterior cruciate ligament is one of the structures that helps stabilise the knee. An injury can occur during a sudden change of direction, an awkward landing or a collision. A pop, swelling, pain or the knee giving way can occur, but similar symptoms can have different causes.
What happens after an injury?
Stop the activity and arrange medical assessment. If the knee is severely painful, visibly deformed, very swollen or you cannot bear weight, seek urgent care. A clinician may examine the knee and recommend imaging when appropriate to look for a fracture or associated injuries.
Does every ACL injury need surgery?
No single approach is right for everyone. Treatment choices depend on stability, other injuries, activity goals and personal circumstances. Some people may be managed with rehabilitation; others may discuss reconstruction. Ask about benefits, risks and the rehabilitation commitment of each option.
Returning to activity
Recovery is gradual and varies between people. A rehabilitation plan can help restore movement, strength and confidence. Return-to-sport decisions should be made with your treatment team, based on progress and the demands of the activity.
