The 25-year-old French forward, who completed a highly anticipated free transfer to the Santiago Bernabéu from Paris Saint-Germain earlier this summer, picked up an apparent knock during a non-contact training drill on September 12, 2024. Initial assessments from the club’s medical staff concluded Mbappé had suffered a mild contusion on his left knee, with a recommended recovery window of 7 to 10 days that would see him miss just two La Liga fixtures against Real Betis and Getafe. However, when the forward reported persistent, sharp pain after completing the full rest and rehabilitation protocol outlined by the team’s doctors, the club opted to send him for a second opinion with independent orthopedic specialist Dr. Juan José Amat in Barcelona. The second examination exposed the staggering error: Mbappé’s injury was in fact a Grade 1 medial collateral ligament (MCL) sprain in his right knee, a condition that had gone untreated for more than a week due to the misdiagnosis. Dr. Amat’s report confirmed that the star forward will now require an additional 3 to 4 weeks of rest and targeted rehabilitation, ruling him out of 5 upcoming La Liga matches, Real Madrid’s first three Champions League group stage fixtures against VfB Stuttgart, Sporting CP, and AC Milan, as well as France’s October international break fixtures. Real Madrid released an official statement on the morning of September 21 acknowledging the diagnostic error, confirming that an internal review of the medical department’s processes has been launched to identify the root cause of the mistake and prevent similar incidents in the future. First team manager Carlo Ancelotti addressed the controversy during his pre-match press conference later that day, calling the error “deeply regrettable” and adding that the entire squad is rallying around Mbappé as he begins his corrected recovery plan. Multiple reports from Spanish sports outlet Marca indicate that Mbappé is disappointed but remains committed to the club, and has opted not to pursue any formal action against the medical team as of press time. The incident has already sparked widespread criticism of the club’s medical operations, with many fans and pundits questioning how such a basic error could occur at one of the wealthiest, most well-resourced football clubs in the world.
