The Spanish playmaker has not featured for Arsenal since October 2016 after requiring surgery to correct the problem.
However, a series of complications led to Cazorla requiring eight operations. The wound did not heal and became infected, sparking fears about his long-term career.
Cazorla’s final operation was the reconstruction of his Achilles tendon back in May of this year and the midfielder has been working on his fitness levels since then.
Doctors took a skin graft from his right arm, featuring a tattoo, and attached it to his right ankle.
And the midfielder has now spoken about how he feared for his career during his lengthy and complicated recovery process.
Speaking to Spanish newspaper Marca, Cazorla said: “Everything that I have gone through has not been as simple an injury as people have believed.
“They [the doctors] told me, if you get to walk again with your son in the garden, be satisfied.”
It is not yet clear when Cazorla will be back available for selection for Arsenal, although he is expected to make his return sometime in the new year.
Arsenal are currently preparing for their crunch clash against Manchester City at The Etihad on Sunday afternoon as they look to close the gap down to the Premier League leaders leaders to six points.
