Arsenal midfielder Jack Wilshere will travel to Sweden later this week for a minor knee operation, as he continues his rehabilitation from an injury that ruled him out for the entire 2011-12 campaign.

The 20-year-old has been plagued by fitness problems over the past 12 months, with both his ankle and his knee, and will be forced to watch England's participation at Euro 2012 in Poland and Ukraine this summer from the sidelines.

A statement released on the Gunners' official website on Thursday afternoon read: "Jack will travel to Sweden for a minor procedure on his left knee in the next few days.

"This procedure is not expected to significantly affect Jack's comeback ahead of next season. On returning to England, he will resume his rehabilitation with the Arsenal medical team over the summer."

The patella tendon in Wilshere's knee is a long-standing issue that has flared up during his recovery, but it should not have any lasting damage.

Arsene Wenger recently explained his intentions to give the England international as much time as possible to complete his comeback, and insisted he will not be rushed into first-team action.

Having not featured for club or country since Arsenal's pre-season campaign last summer, there have been increasing question marks over the player's long-term future, and whether the injury problems will risk ruining his football career.

However, the north London club are convinced that Wilshere can return fitter and stronger than ever, but refuse to be pushed for a specific date or timescale for him to complete his recovery.
