Neal ElAttrache, MD, performed Tommy John surgery on Ken Waldichuk, a pitcher for the Oakland Athletics, in Los Angeles on May 15.
The procedure was a flexor tendon repair and full reconstruction of the ulnar collateral ligament in Mr. Waldichuk's left elbow. In addition, Dr. ElAttrache performed an internal brace procedure, according to a May 16 news release.
Mr. Waldichuk initially experienced discomfort in his elbow at the end of last season in September. In October, Steve Yoon, MD, performed a Tenex procedure and Mr. Waldichuk received a PRP injection to the flexor tendon the following week.
After rehabbing during the offseason, Mr. Waldichuk was shut down following a setback.
The team estimates Mr. Waldichuk will have a recovery of approximately 13 months, the release said.
