One of the most common knee injuries in dogs is a torn anterior cruciate ligament (ACL). Not only is this injury very painful, but it's also a well-known cause of knee arthritis in dogs, which is why many pet parents choose to have it surgically repaired. Proper torn ACL home treatment is as important to a good recovery as the surgery itself. If you find yourself in this situation, here is what you can expect from dog ACL surgery recovery.
What Is ACL Surgery?
Dogs have cruciate ligaments inside their knees that help with stabilization. If your dog starts limping on one hind leg, it's possible that they've torn the cranial cruciate ligament (CCL), which is very similar to the anterior cruciate ligament (ACL) in human beings. An unstable knee creates inflammation, which leads to pain, reduced mobility and early onset arthritis.

Surgery for torn ACLs in dogs is aimed toward stabilizing the knee to reduce pain and slow down the development of arthritis in the knee. There are a couple of different surgical procedures used to repair ACLs in dogs, some of which can only be performed by a board certified veterinary surgeon. Your veterinarian will advise you on what is best for your dog.
Dog ACL Surgery Recovery Tips
Helping your dog through the recovery period is as important to successful healing as the actual surgery. In general, dog ACL surgery recovery takes about six months. During that time, it's vital to keep the following action items in mind.
1. Restrict Exercise
Restricting your pup's movements is critical to dog ACL surgery recovery. You will likely get a couple of pages of discharge instructions from your surgeon that give you specifics, some of which may include:
- Resting as much as possible following surgery for a minimum of four weeks.
- Leashed walking for ten to fifteen minutes and for bathroom breaks only.
- No running, jumping or climbing stairs. Some dogs may need support to get up. You can use a towel as a sling under your dog's belly to help them up.
- Lengthening walks by adding five minutes after four weeks. Just remember to keep your dog away from stairs or hills.
- Extending walks to 30 minutes after six weeks, and incorporating gentle inclines — still no running, jumping or unleashed walks.
Adjustments in exercise restriction will be determined by periodic checkup appointments after surgery to assess how your dog's knee is healing. If your pup is healing quickly they may be able to increase their activity level sooner. If, on the other hand, your pup is taking a little extra time to heal up your vet may advise taking things slower to try reduce the risk of post-operative complications. Regardless, your vet will advise you on how to safely add more exercise to your dog's routine. If you have a hard time keeping your dog quiet during recovery, ask your vet for sedative or calming medications.
2. Monitor Implants
All ACL surgeries require some sort of implant in the knee, and it's important to monitor your dog's surgical site for any signs of implant complications. Signs that there is a complication include:
- Excessive swelling
- Redness
- Pain
- Heat
- Discharge or odor from the surgical site
Dogs are usually sent home with a bandage after surgery to provide compression and support to the knee. It's also important that they wear an E-collar at all times to prevent them from licking the surgical site.
3. Keep All Follow-Up Appointments
Your vet will want to see your dog for follow-up appointments, usually two weeks after surgery, four weeks after surgery and eight weeks after surgery. During these appointments your vet will examine the surgical site, ask you questions about how your dog is doing, remove stitches or staples and take follow-up X-rays to make sure the knee is healing well. Make sure to keep all your dog's follow-up appointments to ensure successful healing and return to function.
