Kvitova faces a lengthy rehabilitation process but she received positive news from her surgeon, who told her she had a chance of resuming playing in six months after the operation went without complications.
The intruder posed as a utility man seeking to read a meter to gain access to the apartment in Prostejov before a struggle ensued.
It is understood the knife was put to Kvitova's throat and her left hand was injured as she pulled the weapon away.
Czech police are still searching for the attacker. The incident has been described as a random act with Kvitova not specifically targeted.
