Prevent Your Dog from Tearing the “Good” Knee Ligament After Surgery

Prevent your dog from tearing the "good" knee ligament after surgeryNothing can be more frustrating and depressing than having surgery on your dog’s knee, paying a lot of money, going through the rehab and ending up exactly where you started. Unfortunately, this situation is fairly common. So how do you prevent your dog from tearing the “good” knee ligament after surgery?

The following scenario is typical in my practice. Your dog has cruciate ligament disease with the recommended treatment being surgery. You are trying to decide what to do! You ask yourself: What surgical technique is best? Should I go to a specialist? How am I going to afford this? All these questions race through your mind. The next, maybe most important and least forgiving question is the following: How do I prevent this from happening in the other “good” knee?


50% of dogs that tear the one cruciate ligament will tear the opposite side sometime in their lifetime. This is the reported statistic. However, it is probably actually more like 70%.

Frequently, just after surgery, the “good” knee is overloaded. This overload or excessive weight-bearing can initiate tearing of the ligament in the “good” knee. At this point and in order to avoid another knee surgery, you must be proactive and aggressive in preventing your dog from tearing the overloaded “good” knee ligament.

Steps in Prevention

1. Prolotherapy- great for this; Read this article!

2. Correct Dietary Issues! Supplementation with vitamins and minerals that aid collagen formation.

3. Pain control and physical therapy in operated leg.

4. Consider hormonal supplementation depending on the individual animal (i.e. testosterone and estrogen).

5. Eastern Herbal- Tendon/Ligament formula by Jing Tang Herbal.

In my practice, I often see both knees having slightly torn ligaments or one knee normal and the other fully or partially torn. However, when both knees are torn, one knee tends to be more clinically significant than the other. These are all unique, different situations and the previously mentioned therapies may still apply. Good Luck!

    My dog tore his ACL awhile back and I’ve been fearful of the day that he might re-injure his leg or tear the other one. Although I didn’t put him through surgery (I used a WoundWear brace) the recovery was still a process. I put the brace on him from time to time when we’re outside because I’m paranoid now. But I’ve not heard of Prolotherapy, the use of hormones or the Eastern herbal medicine as a precautionary measure, so that’s good to know! Thank you for sharing the info!
