We noticed our 4 year old Lab/Rottweiler mix limping on her right hind leg recently, and we took her to the vet to check her out. Our vet diagnosed the problem as a partially torn cranial cruciate ligament, and recommended a $2,500 surgery to fix it. She also mentioned there was a 50% chance our dog would injure her other knee due to the extra stress she's placing on it.
I love my dog, but I'm not willing to shell out $2,500 for surgery that may not even be completely effective. (Our vet made no mention of effectiveness rates, but some Googling seemed to cast doubt on a 100% chance of recovery for the particular type of surgery recommended.)
I also found several websites selling leg braces for dog ACL/CCL injuries that claimed rehabilitation was possible. They had anecdotal evidence that their methods were effective, but I couldn't find any documented research. Is using a leg brace a legitimate alternative to surgery?
