What’s Going On With Kylian Mbappé’s Knee Injury at Real Madrid?

Madrid, Spain – More than two months after Real Madrid’s last medical bulletin on Kylian Mbappé, the club issued a terse update Monday evening confirming what many already suspected: the French forward is still nursing the same left-knee sprain first diagnosed in late December, and no surgery is planned.

The 27-year-old has been managing discomfort in the joint since a blow sustained in the 2-0 La Liga loss to Celta Vigo on 7 December. He subsequently featured in every remaining match of 2025, equalling Cristiano Ronaldo’s club record of 59 goals in a calendar year, yet training-ground sources say the knee never fully settled. Madrid’s New Year’s Eve statement labelled the injury a “sprain” and promised only that “his progress will be monitored.”

That vagueness has become a pattern. The club never offers return dates, and Mbappé’s availability has swung from week to week. He sat out the Champions League visit of Manchester City on 11 December because of what was officially described as “muscular discomfort” in his left leg, then played 90 minutes three days later in a Copa del Rey tie at third-tier Talavera. He travelled separately to Saudi Arabia for the Supercopa de España, appeared for 15 minutes in the 3-2 final defeat to Barcelona, and did not feature in the subsequent Copa elimination at Albacete.

Since January he has started eight matches and scored nine goals, but flare-ups have forced two recent omissions: the second-leg victory over Benfica that sealed Madrid’s passage to the Champions League round of 16, and Monday’s shock 1-0 home defeat to Getafe. Manager Álvaro Arbeloa admitted the decision to rest Mbappé was taken after consultation with medical staff. “When someone isn’t playing, it’s because he’s injured,” Arbeloa said. “We’ll have to wait and see if it’s a matter of days.”

Mbappé underwent fresh scans in Paris last week accompanied by Madrid fitness coach Sebastien Devillaz and physio Willy Zurdo. The findings reaffirmed a sprain; conservative treatment—reduced training loads, no knife—remains the plan. Club sources say there is still no fixed timeline for his return, and day-to-day pain levels fluctuate. One training-ground staffer described “days he feels nothing and others where the pain is sharp,” explaining the on-off selection policy.

The approach has fuelled debate about whether Madrid have allowed an unstable knee to become chronic by pitching Mbappé into must-win fixtures. Medical experts consulted by The Athletic stress that low-grade sprains rarely require surgery, but persistent loading can delay healing. “If a player keeps playing, these injuries tend to worsen the prognosis,” said Juan Ayala, former president of the Spanish Society of Sports Traumatology. “A minimum of three weeks’ rest is required for a grade-one sprain, six for grade-two. If it does not heal properly, it may remain unstable and require surgery later.”

With the Champions League round-of-16 first leg against Manchester City looming next Wednesday and Madrid four points adrift of Barcelona in La Liga, the timing is perilous. Mbappé has supplied 38 of the team’s 87 goals this season (43.7%) and missed five of 15 matches in 2026. France, meanwhile, prepare for June’s World Cup opener against Senegal in New Jersey. Dressing-room sources say Mbappé is “calmer” now that a clearer management plan is in place, yet neither club nor country can say with certainty when he will reappear.

For the moment, all parties continue to wait—hoping the conservative gamble pays off before the season, or the World Cup, slips away.
