In brief: Acl
The best non operative way to tell the difference is by a MRI evaluation.

Other than an MRI, there are some exam findings that could help an experienced knee or sports medicine specialist determine the difference between a partial and complete ACL tear, such as the amount of looseness in the knee, whether there is a soft or solid end feel, and whether the knee twists or "pivots" on stress to the ligament.

In brief: Examination
A full acl tear is unable resist rotational and anterior (frontal) forces that we can test for during a physical exam. A partial acl tear should feel the same as a normal acl or a touch looser. Whether to reconstruct an acl should not be based on an MRI finding.
It should be based on individual activity level and demands. It should be tailored to your individual knee and situation.
