The club confirmed he would be sidelined for a period of up to three months with the Scotland international requiring surgery and an extended rehabilitation period.
The left-back posted an image on his Instagram account from his hospital bed, telling his followers: "Op done. Soup terrible. Thank [you] as always for the lovely messages. Helping me a lot."
A hip injury meant Tierney did not make his Arsenal debut until late September after joining from Celtic on transfer deadline day - making just 11 appearances in all competitions since.
Arsenal have been left short at left-back after Sead Kolasinac was forced off during their 3-0 loss to Manchester City on Sunday.
Eighteen-year-old midfielder Bukayo Saka was utilised as a makeshift full-back by Freddie Ljungberg in Tierney and Kolasinac's absence.
