It appears that the two shows Aerosmith guitarist Joe Perry performed with his sons recently may have aggravated an existing problem with one of the 57-year-old rockers knees and forced him to schedule surgery on March 18.

The surgery has resulted in the postponement of a show on April 5 in Niagara Falls, New York.

Perry, has been suffering with a problem knee for around two years and had been putting off treatment to avoid disrupting Aerosmith’s schedule.
