LATROBE — Seven months to the day after tearing the ACL in his right knee, Rashard Mendenhall said on Wednesday that he’s “right on schedule” with his rehabilitation.

When asked if he has any idea what, exactly, that schedule entails, the Pittsburgh Steelers running back responded, “No, none at all.”

Join the club. After all, uncertainty surrounding recovery from ligament reconstruction surgery is a trend for the Steelers.

Mendenhall is one of three veteran Pittsburgh starters who sustained torn ACLs in January. Nose tackle Casey Hampton and offensive tackle Max Starks each went down during Pittsburgh’s wild card playoff loss in Denver Jan. 8.

Because of the position he plays and the sometimes-violent pressure placed on lateral movement of the knee by a running back, Mendenhall’s recovery is being monitored most closely.

“He has to cut harder,” said Hampton, who is rehabilitating from a torn ACL for the third time, “and have more confidence in his knee before he comes back.”

Hampton said the previous experience he has recovering from that surgery gives him an advantage over Mendenhall. Hampton sustained the injury in 1997 while in college at Texas, and again in 2004 with the Steelers (No. 7 in the AP Pro32). This is the second time he tore the ACL in his left knee; in 2004, it was his right knee.

Hampton, who was on the field stretching with his teammates for the afternoon practice Wednesday, said Mendenhall will be tentative when he first takes part in contact drills.

“No question he will be,” Hampton said. “And that’s how I was when I tore mine, too. That’s just how it is because you’ve just never had it before.

“I know I’m not going to tear anything again. (Mendenhall) might know it — but might not be as confident, you know what I mean?”

Mendenhall, apparently, doesn’t. The Steelers first-round pick in 2008 said he has heard others talk about the mental block of “trusting” the reconstructed knee to be able to handle the extraordinary stress playing professional football places on it.

He just says he’s not experiencing any of that anxiety.

“Mentally, it hasn’t been difficult at all,” Mendenhall said. “It’s really just getting your leg back to normal.”

Fellow Steelers running back Baron Batch sustained the ACL injury Aug. 11 of last season. To that point, he had been making an impression as a standout rookie.

Batch said that, going into that practice, he decided he was going to make the same lateral cut he did when he was injured 50 weeks prior.

“Being able to do that,” Batch said, “helps with confidence.”
