…”ACL surgery is rarely an emergency,” John A. Bergfeld, MD, said. “It doesn’t need to be done the next day.”

…”I wait until the patient can bear weight and has almost a full range of motion,” Bergfeld said. He said he wait from 3 days to 3 weeks after injury to perform ACL injury surgery…

…Operative decisions about in-season athletes with ACL injuries should be made based on the severity of the injury and the sport, he said.

“In general when an in-season athlete injures his or her ACL, I feel that their season is over and they should have surgery when it has settled down,” Bergfeld said.
