Cranial Cruciate Ligament Repair

If your dog suddenly starts limping after exercise/ jumping or falling then then it is highly possible that your dog may have ruptured the anterior cruciate ligament.

After the initial exmination your vet may need sedation and radiographs of your dog to rule out any other possible reasons for lameness.

Once a definitive diagnosis of cranial cruciate ligament rupture has been made then there are different options to fix the problem.

Most commonly used methods for ACL repair are

Non Surgical. for very light weight dogs and cats but your vet will give you the best advice after assesing the circumstances surrounding the injury.

Extracapsular by Sutures, Fibular head advancement and Imbrication
- Suture Repair of the joint is done by replacing the inta-articular ligament with extra-articular substitute like lateral stabilizing suture for dogs under 60-70 lbs and Tight Rope method for dogs above 70 lbs.

Tibial Plateau Leveling Osteotomy; in this method the surgeon changes the slope of the Tibial plateau to stop the slipping of the bones by cutting the bone and then fixing it at different angle by using plates and screws.

Tibial Tuberosity Advancememt; In this method once again the surgeon cut the bone to advance the Tibial tuberosity and fix it with plate and screws at a different angle.

There is no evidence that either of these methods is superior or either of the methods is 100% successful or without complications. But it has been established that after 3-4 months of either procedure the return to normal function is about 85%-90%.

Many factore effect the outcome of the procedure.
