Bethanie Mattek-Sands has announced that she dislocated her kneecap and ruptured a tendon in her sickening Wimbledon fall.
The American will head to New York on Sunday and undergo surgery on the right knee that buckled during her second-round singles match against Sorana Cirstea.
Mattek-Sands has been undergoing scans and receiving treatment at the Parkside Hospital in Wimbledon, a short distance from the All England Club.
The 32-year-old says she has avoided watching replays of her fall and is facing up to a long period of rehabilitation before returning to the game.
"I'm going to be heading to New York City tomorrow to see some more doctors to see what's really going on with my knee," she said on Saturday.
"I dislocated my patella out on the court, that's what the pain was coming from, and I ruptured my patellar tendon and I'm going to be needing surgery.
"So, I'll be out for a while."
The harrowing incident occurred on Court 17 on Thursday, Mattek-Sands collapsing as she rushed towards the net in anticipation of playing a volley.
She was taken from the court on a stretcher and rushed to hospital by ambulance.
She spoke in a Facebook Live video on Saturday and said: "It's obviously been kind of an emotional and painful rollercoaster, the last couple of days.
"I know you've seen the video of the replay and I, for obvious reasons, have not looked at it. I hate watching sports injuries, let alone myself.
"But I was in the middle of my match and playing that last point I was coming to the net, and all I remember is hearing this pop in my leg. Everything was slow after that, it was just this loud pop.
"I have had lots of injuries in my career but this is definitely the worst."
Mattek-Sands is ranked 103 in singles but is one of the world's top doubles players and has teamed up with Lucie Safarova to win the last three Grand Slam titles.
