Philadelphia 76ers center Joel Embiid says he is not as dominant as he once was and needs to fix his injured left knee in order to regain peak form.

Part of the team's struggles stem from the lack of availability from former MVP Joel Embiid, who has played just 18 of the 55 games this season. Embiid had meniscus surgery on his left knee last February and returned to the court in April, but he missed the first nine games of this season due to management of the same knee.
