On 9 October 2014, in the Penguins' first game of the 2014–15 season, Määttä recorded three assists in a 6–4 win over the Anaheim Ducks. During a press conference on 27 October, it was announced that Määttä would undergo surgery to remove a tumor from his neck that could be a low-grade thyroid cancer. On 4 November, he underwent successful surgery and was expected to make a full recovery, and on 18 November, just two weeks after his surgery, it was announced that he would be returning to the Penguins lineup to play that night against the Montreal Canadiens. On 6 December, Määttä re-injured the same shoulder he had surgery on during the off-season—he would go on to miss 16 games before the Penguins would announce, on 13 January 2015, that he would miss the remainder of the season to have another surgery to repair the shoulder. During this time he was also diagnosed with the mumps.
On 18 November 2015, Määttä was slammed from behind into the Minnesota Wild's bench door by Minnesota Wild's right wing Nino Niederreiter, causing him to miss 3–4 weeks with an upper body injury. Määttä experienced soft tissue and muscle damage to his midsection from the boarding. Niederreiter was not suspended for the hit.
In Game Two of the Stanley Cup Playoffs against the Washington Capitals, Brooks Orpik delivered an illegal and late hit to Määttä's head. Orpik was suspended 3 games for the late hit. Määttä returned a few games later and finished the series. Määttä won the Stanley Cup with the Pittsburgh Penguins in the 2016 playoffs.
Määttä left a game against the Winnipeg Jets on 17 February in the second period due to an undisclosed injury. It was later confirmed that Määttä would be out for 6 weeks after undergoing surgery for a broken hand. Määttä returned to the Penguins lineup for the last game of the 2016–17 regular season after missing 24 games.
During the 2017–18 season, Määttä played in his 300th career NHL game against the Washington Capitals on 1 April 2018.[39] He ended the regular season playing in all 82 games and recording 29 points, tying his career high.
Määttä recorded 1 goal and 13 assists for 14 points in the 2018–19 season, placing third on the team with 116 blocked shots and 97 hits in 60 regular-season games.
