## Narrative

EE has recently had arthroscopy surgery to his right knee. He now alleges that he fell on or around Feb. 6, 2012 while hanging curtains.  He states that his knee became increasingly painful and he sought medical attention.  He had not reported any injury to me and I assumed this was a chronic problem that was unrelated to his employment with our company.
