The 23-year-old, who has started every Premier League game for the Gunners so far, has been plagued with two broken metatarsals and a hernia problem in recent years.
"I feel my performances have been positive," said Gibbs. "I've kept fit which has been important for me - especially over the last couple of years where I struggled.
"I always said if I can get a good run of games under my belt, I can always get stronger and hopefully be more consistent - which is what I am doing at the minute.
"I have still got a lot of rehab to be doing from my hernias and from injuries last season. The physios have been really good and pretty much been on top of me from day one."
Gibbs will be expected to start for Arsenal in Tuesday's Champions League match against Olympiakos at the Emirates Stadium.
