## Narrative

On June 23rd of 2009, an employee felt pain in his right knee while moving a ladder.  An MRI showed an accumulation of degenerative changes including tears in the meniscus, and other chronic medical conditions that required corrective surgery on August 31st. Because of the chronic, cumulative, and degenerative nature of the changes to the knee, we consider this to be an illness.
