Cruciate ligament surgery query

My 5 year old Bichon frise fell and has a limp. I took him to vet whom said he needed surgery for a cruciate ligament. One is half of the other in price. Does anyone have should I go with the cheaper option which is surgery without going through bone and putting a bandage type thing under skin or other is through bone or something. Has anyone tell me which is best?

Hello!  You are in luck with this question - top surgeon Rachel Kenvyn has already written an article all about it for Vet Help Direct.  If you go to the blog and put Cruciate ligament into the search bar, you will find a far superior explanation to any I could give you.  Best of luck.
