Suggest Treatment Other Than Surgery For Chronic Rupture In The ACL Of Knee

Dear Sir, I found your email address from the website. I need a small bit of advise. My wife is having problem with her knee for over a year now. In the month of June 2011, after doing MRI, it was detected that there is a chronic rupture in the ACL of right knee. Having understood that surgical reconstruction is the only option available in Allopathy, we started Ayurvedic treatment. But even after 3 months, there seems to be no improvement. Sir, I want to know 1) Is there any other option in Allopathy, apart from surgical replacement ( aged 31 yrs, 155 cm, 58 kgs, she is a school teacher, involves climbing up and down the steps at least 4 to 5 times a day) 2) If no, then are there any risks / after affects involved in surgical method. In anticipation of positive response
