Today, pitchers like Stephen Strasburg and Jordan Zimmermann of the Washington Nationals are back at work. A year ago, 10 pitchers who had undergone the surgery were named to baseball’s all-star team.

“As long as it’s in the right hands,” Tim Kremchek, a leading Tommy John surgeon told The Post’s Adam Kilgore this summer, “the player has over a 95 percent chance of coming back.”

The latest to have the surgery, in which a tendon from the thigh is transplanted in the elbow, will be Boston Red Sox starter John Lackey, who is expected to return in 2013. Overall, more than 150 baseball players, by the Sporting News’ count, have had the procedure.

“I would never have thought it would happen,” said Dr. Frank Jobe, a friend of Tommy John and the orthopedic surgeon who pioneered the surgery, told Kilgore. “It’s been a very fortunate experience for me. It just turned out very well.”

Four things, according to Kilgore, have improved the success rate of the procedure:

●The placement of the tendon graft has become more uniform, which leads to fewer complications for surgeons.

●The operation is less invasive and requires less damage to soft tissue. Doctors no longer cut the elbow wide open, as Jobe did for John.

●Surgeons don’t move the ulnar nerve anymore. About 10 percent of recoveries once either failed or were slowed because of nerve damage. Surgeons learned how to operate around the nerve.

●The most significant development has been a more predictable and comprehensive rehab plan. Pitchers still throw for the first time at around 16 weeks after surgery. Doctors now, though, have a better understanding of how pitchers should strengthen their shoulder and core muscles to take stress off the elbow.
