Defensive end Stephen Bowen underwent microfracture surgery on his right knee last night, according to coach Mike Shanahan, which will require at least a six-month recovery and leading to the likelihood Bowen will miss all of organized offseason workouts.

Bowen originally tore the PCL in his right knee in the Redskins’ loss to the Chicago Bears on Oct. 20 and said he had no plans to have the ligament repaired because it would take a six-month recovery.

He continued to experience soreness in the knee two weeks later, at which point another examination revealed slight tears in the cartilage around the bone. The microfracture procedure is an attempt to repair those tears by stimulating cartilage growth.

“Normally if you need a microfracture there’s a reason for it, so hopefully, this microfracture will help him and when he does come back, he’ll come back full speed,” Shanahan said. “You just keep your fingers crossed. It’s always tough going through rehab.”

Bowen, 29, signed a five-year, $27.5 million contract before the 2011 season and was scheduled to make $4 million this year with a $5.5 million salary cap hit. He renegotiated the terms at the end of the preseason to give the team additional flexibility under the salary cap, taking an $840,000 annual salary this year – the minimum allowed for a veteran in his eighth season.

The 6-foot-5, 310-pounder could face a prolonged recovery, and there’s no guarantee that the microfracture surgery will allow him to return to the field and resume his role as a starter.

“Stephen is a worker, and it’s always unfortunate to have a surgery like that, but he’s young, he’s a worker, so I’m sure he’ll bounce back very quickly,” Shanahan said.
