This procedure uses a fresh approach to the biomechanics of the knee joint and was developed with larger breed dogs in mind. The idea is to change the angle at which the femur bears weight on the flat “plateau” of the tibia. The tibia is cut and rotated in such a way that the natural weight-bearing of the dog stabilizes the knee joint. The knee joint still must be opened and damaged meniscus removed. The cruciate ligament remnants may or may not be removed depending on the degree of damage.
This surgery is complex and involves special training in this specific technique. Many radiographs are necessary to calculate the angle of the osteotomy (the cut in the tibia). This procedure typically costs substantially more than other techniques.
• Typically, most dogs are touching their toes to the ground by first day after surgery although it can take up to 3 days.
• As with other techniques, 8-12 weeks of exercise restriction are needed.
• Full function is generally achieved 3 to 4 months after surgery and the dog may return to normal activity.
• There is enough evidence that a partial ruptured cruciate ligament can repair itself after a year post TPLO surgery.
