Derrick Rose -- Injured NBA Superstar Limps Out of Nightclub

Chicago Bulls superstar Derrick Rose still isn't healthy enough to get on the court ... but he felt like hitting the club scene in Hollywood last night ... gimpy knee and all.

TMZ shot footage of the 23-year-old -- who tore his left ACL back in April -- limping his way out of The Roxbury nightclub around 1:30 AM ... surrounded by his entourage.

Yes, we know, we asked a stupid question considering the situation ... but still, Rose's appearance at the club is a pretty shocking move, considering he signed a $95 million contract extension back in December. Taking his busted knee to a place filled with stumbling, drunken people might not be the wisest decision.

Rose reportedly had surgery on the knee on May 12 -- and depending how his recovery goes, he could miss the start of next season.
