“I think in that moment Sorana was there as my friend,” Mattek-Sands said. “It doesn’t matter that it was in the middle of the match. It means a lot to me—she’s an amazing person.”

She added: “I was out there for a while. It felt like an eternity to me. I juust remember everybody getting ready to straighten my leg and I kept telling [my husband], I said if anybody straightens my leg I’m going to kill you.”

Mattek-Sands said she dislocated her patella and ruptured her patella tendon. She said she will need surgery and will be out for a while.

Surgery from a torn patella tendon usually takes a rehab period of 4-6 months.

“All the support has really been getting me through this,” she said. “So thank you, I’ll get back out there.”
