India's top women tennis player Sania Mirza on Saturday underwent a 'successful' surgery on her left knee, which she injured during October's US Open, her father Imran Mirza said.

Imran informed that Sania had torn her meniscus during the US Open Grand Slam tournament in Flushing Meadows last month.

"The surgery was performed by the Orthopaedic Surgeon, Dr. K.J. Reddy. Her Pakistani cricketer husband, Shoaib Malik was present at the hospital when the operation was performed," Imran said.

It may be recalled here that Sania had earlier undergone an arthroscopy after damaging her ACL on the right knee in 2006 and a right wrist surgery to repair a torn lunate capsule in 2007.

Sania Mirza had broken into the top-10 of the world in women's doubles for the first time in her career when she was struck down with the knee injury during the year's last Grand Slam
