The Paraguay defender joined the Toffees from Wigan Athletic last summer, but did not make his debut until December, and scored an own goal during one of his seven appearances.
The 31-year-old told evertontv: "On a personal level, it's one to put behind me. It's one to forget almost as it's been full of negatives.
"The frustration as a player is that an injury stops you doing what you most enjoy. It's almost like it is taking your liberty away from you and you become a prisoner in your own situation.
"I took solace in that I was able to play a few games towards the end of the season and physically I came through those okay, and that is promising for next season. What I want more than anything is to make sure that I am 100% fit, totally free from injuries and have the chance to do what I do."
Alcaraz's own goal against Southampton is the fastest ever to be scored in the Premier League.
