Joel Embiid has had two surgeries on his troublesome left knee. It's swelling again -- and no one knows why. What he does next could determine the future of the 2023 NBA MVP.

Joel Embiid has been the superstar of the Philadelphia 76ers franchise for almost a decade now, but he seems unable to stop getting injured. His knees are his biggest problem, and the severity of his problems that stem from them might force him to retire.

Last season, Embiid was in the midst of one of the most prolific individual campaigns in NBA history before tearing the meniscus in his left knee. He’s struggled this year to gain full strength.
