Hill underwent an arthrogram test Friday on his injured left hip, and results showed that he has loose fragments in addition to a possible torn labrum, according to the Lakers.
Hill has been advised that surgery will be needed to repair the injury, which would cause him to miss the remainder of the season. He will seek a second opinion before he schedules surgery, Hill's agent, Kevin Bradbury, told ESPNLosAngeles.com.
If Hill opts for surgery, the recovery period would be approximately six months, according to Hill.
"I'm definitely heartbroken," Hill said after the Lakers lost 116-101 to the Oklahoma City Thunder on Friday to fall to 15-21.
Hill injured his hip against the Denver Nuggets last week and has missed the Lakers' past three games. The injury occurred in the second half when Hill got tangled up with teammate Kobe Bryant when he was going to defend Denver's Andre Miller as he drove baseline.
"Kobe accidentally stepped on my foot, and it kind of took my leg out of place," Hill said.
After the Lakers' sixth straight loss, Bryant expressed concern for Hill amidst the team's turmoil.
"I'm just more disappointed for Jordan," Bryant said. "He's really worked hard. He played well for us last year, he's been playing well for us this year. I'm just really disappointed for him."
Hill doubted the second opinion would change his course of action to undergo a procedure.
"I definitely need surgery," Hill said. "It's definitely mandatory. They said I have fragments floating around that need to be out. It definitely needs to get done."
The Lakers entered Friday ranked 26th in the NBA in bench scoring at 26.2 points per game, and Hill was a big reason that ranking wasn't worse. The four-year veteran is averaging 6.7 points and 5.7 rebounds in 15.8 minutes per game.
Hill, 25, signed a two-year deal worth approximately $7 million with the Lakers in the offseason.
"It took a while to process; I've never been out this long," Hill said about hearing the news of how long he will be sidelined following surgery. "It hit me hard, and it's still hitting me."
