Dr. Thomas Clanton cleaned out scar tissue and debris in the joint and also performed a bone graft, according to a team news release. Clanton previously served as team physician for the NBA's Houston Rockets and NFL's Houston Texans, and is currently the director for Foot and Ankle Sports Medicine at the Steadman Clinic.
"I knew the road back ... there were going to be issues along the way," Morales said through a translator on May 11. "Obviously, I wasn't ready to have surgery again, but at this point I think this is the best decision for everybody involved to get me back 100 percent as soon as possible."
Morales first hurt the ankle in a celebration at home plate on May 29, 2010, and the first surgery took place June 10 of last year. Dr. Phil Kwong oversaw that operation.
There is no timetable for Morales' return, although he is definitely out for the remainder of the 2011 regular season.
