Denver Nuggets forward Danilo Gallinari underwent surgery this morning to reconstruct an ACL tear in his left knee.

The surgery was performed by team Orthopedic Surgeon Dr. Steve Traina at Midtown Surgical Center.

“It was recently determined that the procedure that Danilo underwent on his knee this past summer was insufficient,” Nuggets General Manager and Executive Vice President of Basketball Operations Tim Connelly said.

“Danilo’s knee required that he undergo reconstruction of the ACL, which was successfully completed earlier this morning. Knowing Danilo’s drive and work ethic, we look forward to a full recovery and a healthy return to the court next season.”

Gallinari tore his ACL on April 4, 2013, against the Dallas Mavericks.
