Modern sports, particularly baseball, wouldn’t be the same without the advent of Tommy John elbow reconstruction. In the old days, when a baseball player developed what was often called a “dead arm” nothing could be done except tell him it was time to retire.

Hall of Fame left-handed pitcher Sandy Koufax retired at the age of 30, because he reportedly had an arthritic left elbow that hurt almost constantly when he pitched. But some think he really needed Tommy John surgery.

How many more years could Koufax have pitched if he had had the surgery? Another five to ten years? Who’s to say? Too bad Koufax wasn’t born about ten years later!

Let’s explore Tommy John surgery and see how many Major League Baseball players have had this now commonplace operation.

What is Tommy John Surgery?

The human arm is comprised of three bones, the humerus, radius and ulna. Ligaments hold these bones together and allow movement at the elbow and wrist. The ulnar collateral ligament (UCL), located inside the elbow, connects the humerus (the upper arm) to the ulna (the lower arm). When, because of repeated stress, the UCL tears, the player can no longer throw the baseball effectively.

In order to restore stability to the UCL, a tendon is taken from another part of the body, usually the arm, leg, hip or foot, and this autograft is then used to create a new UCL. (A tendon from a cadaver can also be used for the procedure.) Holes are drilled into the humerus and ulna bones and then, using a figure-eight pattern, the autograft is attached to the bones, creating a new UCL that is just as strong as the original.

Interestingly, many tendons in the human body, particularly the one attached to the palmaris longus muscle in the forearm, are not crucial for movement; therefore, many of them can be used as autografts in UCL reconstruction!

Recovery time from this operation takes from nine to 18 months and the success rate is from 85 to 95 per cent. Athletes from various sports have undergone UCL reconstruction but most are pitchers in Major League Baseball. Minor League Baseball players and college players have also had the operation. Moreover, Miami Marlins pitcher Nathan Eovaldi had Tommy John surgery while he was a junior in high school!

Enter Tommy John

Back in 1974, Los Angeles Dodger left-handed starting pitcher Tommy John had a stellar record of 13 and 3 at the All-Star break, yet for some reason he wasn’t selected for the All-Star team. Reputedly upset at being snubbed, he blew out his elbow in a subsequent game. (Players report hearing a “pop” when the elbow fails.) At this point John found himself with the classic dead arm. Time to retire!

Then in September 1974, legendary surgeon Dr. Frank Jobe proposed trying a new surgical procedure on John. John agreed to try it and underwent UCL reconstruction. John spent all of 1975 recovering from the operation.

During John’s recovery, teammate Mike Marshall, a right-handed closer for the Dodgers, taught John how to pitch without putting unnecessary stress on his pitching arm and both knees. This certainly helped with John’s rehabilitation process.

Now called “the Bionic Man,” John resumed his baseball career in 1976 and compiled a record of 10 and 10, considered a miraculous achievement by baseball experts. John continued pitching until 1989, winning another 164 games, one less than Koufax did in his entire career!

Thereafter, UCL reconstruction has been dubbed by baseball enthusiasts as Tommy John surgery.

What Tommy John Thinks about Tommy John Surgery

Reacting to the recent rash of Tommy John surgeries in MLB, in May 2014 Tommy John said, "Throwing pitches in the big leagues will not hurt your arm," John told the Daily Times, as reported by ESPN. "It's what you did down the road when you were younger. ... In essence, the injury itself is a buildup of overuse. And not overuse as an adult, but overuse as a kid.

"What I would like to see these guys do, these surgeons and all, is ask all the guys who have had the surgery -- 'How much did you pitch as a kid and how often, and did you pitch year-round?' And nowadays, probably 70 to 80 percent of the pitchers today have been pitching 12 months a year since they were seven, eight or nine years old. And your arm is not made for that."

Exit Hong-Chih Kuo

Major League relief pitcher Hong-Chih Kuo has the dubious distinction of being the MLB player with the most Tommy John surgeries – four! Kuo first blew out his left elbow in 2002, when he had two UCL reconstructions. And then in 2003 he had two more! Keep in mind, there’s never a certainly that the operation will be successful. Kuo wasn’t able to pitch effectively again until the 2005 season.

Nicknamed “Status Kuo” Kuo (pronounced “quo” as in quote) had an excellent year in 2010, making the All-Star team, while becoming the closer for the Los Angeles Dodgers. That year Kuo led all relief pitchers in the majors with an ERA of 1.20.

But Kuo’s career went downhill from there as he continued to struggle with elbow problems and an anxiety disorder. Kuo last pitched in the majors in 2011.

What about Jose Rijo?

According to the article “Tommy John Surgeries: A More Complete List,” on the website Beyondtheboxscore.com and last updated in November 2012, pitcher Jose Rijo may have had as many as five Tommy John surgeries, but the dates of these surgeries cannot be confirmed.

How many MLB players have had Tommy John surgery?

In reference to the aforementioned article on Beyondtheboxscore.com, 488 Tommy John surgeries have been performed on both major and minor leagues players since the surgery was first introduced in 1974.

Per another article on the website Baseball Reference.com, last updated in January 2015, the list provided shows the names of 296 MLB players, active and retired, who have had Tommy John surgery. However, the author knew the name of at least one active player whose name should have been on this list, so the accuracy of this compilation is questionable. (By the way, this list showed that Jose Rijo had five TJ surgeries.)

Moreover, the aforementioned website stated that at the time of Dr. Frank Jobe’s death in the spring of 2014, one third of all MLB pitchers have had Tommy John surgery. It also stated that during the 2000s an average of 16 pitchers had the surgery each year. And, in 2012, a record 36 pitchers had the surgery!

According to an article on the website hardballtimes.com entitled “Major Leaguers’ Tommy John Surgeries Trending Down,” a total of 15 MLB players had Tommy John Surgery in 2016. This was a decrease from a total of 27 in 2015. The article suggested that the decrease was because some players chose less invasive procedures such injections of stem cells or platelet-rich plasma. The results on both treatments have been mixed at best.

Including data from a list found on Tommy John Surgery List @MLB Player Analysis, about 19 MLB players had TJ surgery in 2017, making a total of 434 MLB players, active and otherwise, that have had Tommy John surgery. But if you want a total that includes all MLB, minor league, college and even high school players, the grand total is 1,484 players.

Of course, whatever the total may be, it seems to change every week or two, especially during baseball season. Just hope your favorite player doesn’t need Tommy John surgery any time soon, if ever.

        Does anybody know the success rate of pitchers that come back from Tommy John compared to the failure rate? So out of 488 pitchers that had Tommy John, how many came back and actually pitched well compared to how many came back and failed?

        This is a little bit late but can anybody find or come up with what percentage of Tommy John surgeries are performed on pitchers vs position players. Corey seager's recent injury got me thinking about this.

        Glad I read this. Never followed up on what sports announcers were talking about when referencing Tommy John surgery. Amazing the things that can be done with ortho surgery.

        And now you have another Dodger who has had Tommy John surgery -- Carl Crawford. Although he had the surgery a couple days before he was traded to the Dodgers around a week ago.
