Patient: How do I know if my ACL is torn? I hyperextended my knee.
Doctor: Thank you for your question. The anterior cruciate ligament functions to stabilize excessive forward movement and media l rotation the tibia (the bone of the lower leg beside the shin bone) in relation to the fibula (shin bone). An ACL tear is very painful and suddenly occurs with a sudden ‘popping’ noise. Furthermore, you will notice pain and swelling shortly after the injury behind the knee. Your knee will be painful to walk with and you will have the sensation of your knee ‘ buckling or giving away’ underneath you as you attempt to walk. Please be guided accordingly.Thank you for choosing AskTheDoctor.com
