February 2011 saw Karlović temporarily exit from the top 200.
In 2012, Karlović beat Dudi Sela in the first round of Wimbledon in straight sets, but was knocked out in the second round by Andy Murray.

In 2013, Karlović suffered from viral meningitis, which was not immediately diagnosed.
He was unconscious for some time, and when he woke up, he did not know his name or what year it was.
After a lengthy recovery, he was able to play again in Newport in July, where he made it to the quarterfinals, before being defeated by John Isner in one of their typical ace-fests.

In Bogota, also in July, he won his fifth ATP title, beating Alejandro Falla in the final.
He did not qualify for the Rogers Cup or Cincinnati Masters.

At the US Open, he made it through qualifying and into the second round by defeating James Blake in the last singles match of his career in five sets.
In the second round, he met Stanislas Wawrinka, to whom he lost in straight sets.
