Maybe.
It frustrates me when people say 'its just a sprain'. A 'torn ACL' is a sprain that's severe enough that it won't heal on its own. Same with UCLs.
Its a pet peeve of mine and I know it. I blame Will Carroll. This, along with 'could care less', are two things I just can't let go.
Their is a difference between a sprain and a tear. A grade 1 or 2 ACL injury is a sprain, where the ligament has tearing, but remains intact, and has the ability to heal on its own with rehab. A grade 3 is where the ligament has partially, or completely torn and is no longer intact , and will require surgery for it to completely heal.
