California governor Arnold Schwarzenegger had surgery this weekend to repair a knee injury he recently suffered while working out.

The Austrian-American movie star, who was elected into California state office in 2003, was in good spirits following the operation on Saturday - and even attended church the following day, walking without assistance, his representative reports. Spokesperson Matt David says the knee "was just giving him a lot of discomfort," and that the actor had "said the surgery went well".

The arthroscopic operation, which took 45 minutes, is the second time the 61-year-old has been under the doctor's knife in 20 months. He had surgery in December 2006 after fracturing his right femur in a skiing accident.
