Patriots star tight end Rob Gronkowski will undergo surgery to repair a torn ACL and MCL in his right knee on Thursday, a league source confirmed to the Globe on Tuesday morning.
Gronkowski will have the surgery almost exactly a month after suffering the injury on Dec. 8 against the Browns. Dr. James Andrews, who previously consulted with Gronkowski on his forearm injury, will perform the surgery in Pensacola, Fla.
Gronkowski needed the swelling to go down in his knee before surgery could be performed. While his availability for the start of training camp in late July is in question, Gronkowski hopes to be healed by the start of the regular season.
This will be the sixth surgery for Gronkowski since November 2012. He has had four surgeries to repair a broken bone and clean out an infection in his forearm, and back surgery to repair a herniated disc in June. He played in seven games for the Patriots this season, catching 39 passes for 592 yards and four touchdowns.
