Actor Jang Dong-gun underwent knee surgery at a general hospital in Seoul earlier this week and was discharged on Friday, officials from his agency said.
``Jang had surgery to repair damaged cartilage in his left knee and was discharged from the hospital as the surgery went well,'' an official said. ``He will concentrate on rehab for a while.''
Jang sustained the injury in 2003 while he was acting in the movie ``Taegeukgi.'' He previously had surgery but failed to recover from the injury completely.
The next film Jang will star in is director Kang Je-gyu's ``D-Day,'' which will start shooting in May.
