Mumbai, July 25 (IANS) After attending the trust vote in parliament, veteran actor and Bharatiya Janata Party (BJP) MP Dharmendra is recuperating at his home here before he leaves for Los Angeles where he underwent a knee surgery.

According to a close friend, the actor's knee problem is a consequence of the dare-devil stunts he used to do in films in his heydays.

The BJP MP from Bikaner in Rajasthan had to rush to India from Los Angeles early this week to attend the crucial trust vote faced by the Manmohan Singh government. He flew down to New Delhi July 22 to cast his vote against the government, according to the party diktat.

'The actor's advancing age is also a factor, but the disorder in his knees aggravated mainly as a consequence of the dare-devil stunts he used to do in films. He used to do his stunts like falling off a running horse, jumping out of a speeding vehicle himself. Only later he started using a body double,' said the family friend.

Dharmendra had knee transplants on both his legs and is still on a wheel chair. His doctor had accompanied him from the US.

His eldest son, Sunny Deol, who is now in London, will join his father in Los Angeles, where he will take further treatment for his knees.
