The Cruciate Ligament is an integral part of the knee joint, and often one that ruptures with sudden movement, stopping, twisting or jumping.


Both cats and dogs can rupture the Cruciate Ligament, however dogs (especially active dogs) are the most likely to present to us with this form of injury.


Surgical repair is crucial - without repair, the animal suffers from pain, lameness, and often ruptures the Cruciate Ligament of the other leg.


There are two techniques for Cruciate Repair that we use, each suitable for different sizes of dogs.


Tibial Tuberosity Repair Technique

The Tibial Tuberosity Technique, or TTA, is a new generation for the surgical repair of a Cruciate Rupture in dogs, especially medium to large breed dogs. The TTA technique involves changing the angle of the Tibia, which in turn removes the knee's reliance on the damaged Cruciate Ligament. To do this we make an incision into the bone, change the angle of the front section and secure it with Titanium Screws and a Titanium Plate. We then fill the new area with Bone putty, to stimulate healing and the generation of the new, bony substance which will fill the gap as the body heals. Depending on the case, we may also go into the joint capsule to clean any remaining debris.


Extra Capsular Cruciate Repair

The Extra Cranial Cruciate Technique involves creating a new, synthetic Cruciate Technique to take the place of the repaired ligament. To do this, we go into the knee joint and clear the joint of debris. We then use a Cruciate tie, which is implanted, along with crimps to hold it in place. This technique to suitable for medium and small breed dogs and cats.



With proper rest, rehabilitation and a slow introduction back to physical activity, which our Vet will take you through, animals make an excellent recovery. The joint is more prone to earlier arthritis in future years, so many people consider Stem Cell Therapy or arthritis support as an excellent option to repair the joint's cartilage.
