In the wake of New York Giants defensive lineman Fred Robbins’ disclosure that he had microfracture knee surgery before later removing the information from his blog, questions are being raised about the extent of fellow defensive tackle Barry Cofield’s offseason knee surgery.

Cofield recently characterized his repair procedure as “an advanced scope,” according to Ralph Vacchiano of the New York Daily News.

Yes, microfracture surgery is an arthroscopic surgery. However, it takes much longer to recover from than your garden-variety arthroscopic surgery.

Although Giants coach Tom Coughlin emphasized that Cofield did not undergo the same surgery as Robbins, Coughlin clammed up when pressed for details.

“You know what?” Coughlin told reporters. “That’s not going to come from me. [Cofield] had a scope and he’s doing well. You see him running.”

Coughlin did point out that Robbins is further along in his rehabilitation than Cofield.

Just in case both Robbin and Cofield are sidelined for an extended period, the Giants went out and acquired some reinforcements during free agency by signing defensive tackles Chris Canty and Rocky Bernard.
