Triple Tibial Osteotomy

Cruciate Ligament Rupture

latThe cruciate ligament in the dog is prone to rupture, just as it is in humans. The cruciate ligament attaches between the femur and tibia in the dogs stifle joint (like our knee). It is most prone to rupture in large breed dogs, such as Labradors, Rottweilers and Golden Retrievers, but we do see the problem in every dog breed.

Dogs that rupture their cruciate ligament experience pain and are prone to getting severe arthritic changes in the joint. The unstable joint can also put extra pressure on the cartilaginous cushions within the joint (menisci) which are prone to tearing.

We recommend surgical stabilisation of the stifle joint in dogs with cruciate rupture. In small dogs (less than 10 kilograms) this is achieved by placing a strong nylon suture around the joint, through a hole drill in the tibia and attached to the back of the femur.

In larger dogs this method of stabilisation has been found to be less than perfect and we recommend alteration of the joint angles to stop the shearing forces created within the stifle that no longer has a cruciate ligament.

There are several procedures that achieve this result in dogs, the TPLO (Tibial Plateau Levelling Osteotomy) is a specialist procedure performed by specialist surgeons for the last 15 years or so with very good results. More recently a similar procedure was developed that has been adopted by the Gippsland Veterinary Hospital that gives comparable results to the TPLO, but can be performed in Maffra. The procedure called a TTO (Triple Tibial Osteotomy) is designed to alter the joint angles in an operation that involves cutting the tibia and removing a wedge of bone then securing it with a stainless steel plate.

Dr Duncan Runciman has now performed over 100 TTO’s and takes referrals from other veterinarians across Gippsland. The results are generally excellent and most dogs return to normal function within 3 months of surgery.
