Dr. Lewis Yocum performed the operation Friday. Red Sox manager Terry Francona said the noted surgeon was pleased with the results.
Francona said Matsuzaka has an appointment with Yocum in 10 days then he should be able to "start doing things."
Matsuzaka is in the fifth year of a six-year deal he signed when Boston brought him over from Japan. With a recovery time of 12 to 14 months, his future with the Red Sox is uncertain.
Lefty reliever Rich Hill on Thursday also had Tommy John surgery. Francona said Hill told him that he was doing well.
