Cushing, 28, did not miss any time with the injury, but he did sit out a pair of games to rest his left knee. He suffered a torn ACL in 2012 and broke the knee in 2013 while also tearing his LCL.
It is expected that Cushing will need three months to fully recover from the surgery.
"I got surgery because it was something that had to be fixed," Cushing said.
"But I was playing with it broken for a while. ... It was kind of one of those things, after a game I woke up and it was sore. I've bumped my wrist before ... didn't think it was a big deal, got a little better, got a little worse. This kept getting worse and worse. I figured something was up with it."
In 14 games last season, Cushing had 72 combined tackles, one forced fumble and one sack. He has played his entire career in Houston since being the No. 15 pick in the 2009 draft.
The Texans finished 9-7 and in second place in the AFC South, missing the playoffs.
