Active Young Dog With One Torn and One Partly Torn Cruciate Ligament

Reader Question
My dog is 2 years old. The other day he tore his cruciate ligament in his right knee and while having x rays they determined his left one was also partially torn. He is an extremely active dog. I've had one vet tell me that surgery is the only option but if they plate the knee then he can't bend it anymore. And another vet told me that sometimes its better to let it scar up and heal with no surgical intervention. I don't know the right way to go. Is it true that the knee can heal itself? I don't want my dog to not be able to bend his knee again. Like I said he is extremely active.


Answer from Our Team

TPLO, the plate-based surgery, doesn't stop the knee bending. The plate holds a cut in the shin bone while it heals, and the knee still bends afterward; most dogs regain good, active use of the leg. In a randomized trial of 80 dogs, 93% of TPLO owners rated their satisfaction 9 or 10 out of 10.

A torn cruciate ligament doesn't heal back together. Some small dogs stabilize with scar tissue, but in a young, very active medium or large dog, surgery usually gives the best long-term function. Partial tears usually progress to full tears, so ask a surgeon about treating both knees, often in stages.
