## Narrative

Employee was stepping off a mill to the catwalk and stepped on an airhose.  He twisted his left knee.  Pain persisted so an MRI was done in April, a minor tear was found.  Employee has personal health issues so surgery was put off until 5/3/07 (just prior to the shifts long weekend).  Employee was allowed to return to work with restrictions.
