The Gunners star finally had an operation on an issue that had lingered for a while and seen him play through the pain barrier for many months.
Arsenal medics believe White returning within three months will be a bonus, and manager Mikel Arteta will hope to have him back sooner rather than later given his versatility.
Fortunately, the North London club have options who can cover in his long-term absence, with the likes of Jurrien Timber, Riccardo Calafiori, Jakub Kiwior, Thomas Partey, Myles Lewis-Skelly and Oleksandr Zinchenko all available options at full-back.
