In brief: Pop, pain, swelling
The most common symptoms of acl injury are a non-contact twisting or hyperextension injury to the knee associated with an audible or palpable pop followed by pain and swelling.
Contact injuries are also common. Typically, the knee will swell for several days. Even though you may be able to bend it and walk on it eventually, most patients continue to feel instability or "giving way" or buckling.

In brief: Instability.
Your knee may feel unstable, or like it wants to "give out" on you, especially with twisting activities.
You may have some pain also, particularly if any of the menisci are injured.
