Prognosis obviously depends on the severity of the injury. A Lis franc injury is used to describe the rupture of the ligament from the medial cuneiform to the second meta base and is sometimes accompanied by fracture/dislocation of the metabases 2-5. Either way, the treatment is usually surgical (especially on an athlete that wants to continue a career).
Prognosis is usually best if it is solely a ligamentous injury and a screw is shot across the joint to "re-create" the ligament. Even still, the prognosis isn't wonderful secondary to arthritic changes in the joint causing a lot of discomfort down the road. Many times, even these patients don't reach what they would consider to be 100% but it does happen.
If there is a fracture/dislocation of one or multiple meta bases, it will require various screws and pins and the prognosis is worse (again secondary to the development of arthritis in the joints).
Again, without seeing BIG MR. FREENEY, it is hard to say. But Lis Franc injuries are generally very nasty injuries. Mike Brown of the Bears had a Lis Franc injury last year and did return to play this year (until he got hurt again)!
