Tibial Plateau Leveling Osteotomies (TPLO)

Tibial Plateau Leveling Osteotomies—or TPLOs—are the most common orthopedic surgery in dogs today.  The procedure is used to treat canine cranial cruciate ligament deficiency, to stabilize the stifle joint after the cranial cruciate ligament ruptures, similar to an ACL tear in humans.  Dr. McAbee has been performing TPLOs since 2005 and has performed this procedure thousands of times..

The procedure utilizes a circular osteotomy (cut in the bone) in the top part of the tibia. The top segment of the tibia is then rotated to a more horizontal position relative to the ground and then held in place using a bone plate and screws. This results in a much more stable knee when the patient bears weight on its leg.

In the majority of dogs, the ligament ruptures as a result of long-term degeneration.  Though we do not know exactly why, certain breeds such as Labradors, Rottweilers, Boxers, West Highland White Terriers and Newfoundlands are predisposed to the condition.  Limping is the most common symptom and may begin after playing or other vigorous activity. If you suspect your dog has suffered an injury to their cranial cruciate ligament (CCL), have your veterinarian evaluate your pet as soon as possible. If your veterinarian diagnoses a CCL injury in your dog your family member may be a candidate for a TPLO.
