Can a torn knee ligament of dog be healed without surgery?

In most instances, the answer to this question is no, a torn knee ligament of a dog cannot be healed without surgery. The only possible exception to this rule may be if the dog has a very small partial tear of the ligament, and the dog is kept completely immobile for a period of several weeks while the ligament heals. Even then, surgical repair is often necessary to ensure that the ligament heals properly and the dog does not suffer from long-term lameness or instability.
