The Jags midfielder was forced to pull out of the Scotland Under-21 squad that went down 4-0 in Holland last week due to an ongoing ankle knock.
Bannigan suffered the injury during Thistle's pre-season preparations and, after starring in their 2-1 win over St Mirren last time out, he is determined to play his part when Aberdeen visit Firhill this weekend.
Bannigan said: "It is still a bit sore but I think the couple of days off and a couple of days of strengthening work have helped me.
"It has been a problem for a while but hopefully I can get over it and kick on again.
"I don't notice it much in games, it is more the aftermath of games and training.
"I will keep doing some strengthening work and hopefully I will be fine.
"I am not taking injections or anything like that yet.
"It was disappointing to have to pull out of the U-21s squad.
"It would have been a great game to be involved in against a really good side.
"England and Holland are two really good sides and we are a young team just now.
"It would have been good to have been involved, it would have been a good learning experience.
"Hopefully, I can play well for Thistle and get back into the squad."
Despite struggling to reach peak fitness so far this season, Bannigan has enjoyed a superb start for in-form new boys Thistle.
The Jags have taken the Scottish top flight by storm in the opening weeks of the campaign, collecting eight points from their first five SPFL Premiership fixtures.
Alan Archibald's side have drawn both their home fixtures this season as Dundee United and Hearts left Firhill with a point.
And Bannigan knows they will have to be at their best to see off the Dons this weekend.
He said: "It will be a good game. Aberdeen will bring a big crowd and we want to get that first home league win.
"The fans have turned out in their numbers for us and we want to give them a home win in the league.
"We were unlucky in the Hearts game but the Dundee United game was probably a fair result.
"The home form was great last season and we want to do the same again this year.
"Aberdeen are a really good side and players that can cause you problems.
"They have been tipped to do well this season but we go into every game looking to win it.
"Aberdeen are a big club and they can attract good, experienced players.
"We are a young team but we are playing well and full of confidence so we are looking forward to the game.
"The league is a lot faster but I am enjoying it, I think we have surprised a few people with the start we have made."
