Sania Mirza undergoes a successful knee surgery

India's top women tennis player Sania Mirza Saturday underwent a "successful" surgery on her left knee, which she injured during the last month's US Open.

Her father, Imran Mirza informed IANS that Sania had torn her meniscus at the Flushing Meadows. She is expected to resume practice in four weeks' time.

The 24-year-old had the surgery in the Apollo Hospital in Hyderabad Saturday morning. "She underwent a successful knee surgery this morning. She will be going through a rehab, which will begin after a week of complete rest," Imran Mirza told IANS. "If all goes well, she should be able to resume practice in four weeks' time."

Sania had broken into the women's doubles top-10 ranking for the first time after the US Open but has been out of action since.
