What should i do with my torn acl?

See an orthopedist: Acl tears should be individualized to each patient. There is no one way to treat an acl tear. Depending on your activity level, age, and overall conditioning, a surgeon may recommend nonsurgical management, surgery with your own tendon, or surgery with a donor tendon. Some cases require additional procedures to fix the overall problem.

Yes you should: When you tear an acl, a person often feels as though the knee went the wrong way. It is usually a non-contact injury. The knee will swell. Later after recovery from the pain and swelling of this first injury, the knee often feels great. The symptoms then are of recurring instability like you don't trust the knee or it gives out. So the symptoms actually change with time. Surgery is usually the tx.

See a specialist: Absolutely see an orthopedic sports medicine specialist to discuss treatment. Surgery vs non operative treatment, graft options (yours vs cadaver, which tendon specifically, etc) and treatment of any associated injury should be discussed in detail. If you wish to remain active in agility sports you should really consider surgery. If the decisions are tough consider a second opinion. Good luck.
