Real Madrid said in a statement that Kylian Mbappé sustained a posterior capsule hyperextension of his left knee during France’s 1-0 win in Türkiye on Friday. The club confirmed the diagnosis on Saturday.
A hyperextension occurs when the leg and knee joint straighten beyond their normal limit. “Normally, when you load the knee it is slightly flexed, which protects the tendinous structures. Here the tibia is driven forcefully backwards beyond what the joint can usually allow,” said Dr Jean-Bernard Fabre, a sports science doctor, in Le Parisien.
Hyperextension describes the mechanism rather than the injury itself. The immediate consequence is often tendon damage, with severity ranging from irritation to a complete rupture.
Real Madrid do not appear especially concerned about the severity of this lesion.
Spanish media have suggested the France captain could return within two weeks, which would mean he does not miss a match for Madrid.
