Rehabilitation prognosis positive after TPLO surgery in an agility dog
Signalment Kahlar, 8-year-old, spayed female, mixed breed weighing approximately 40 pounds.
History Kahlar began training agility at the age of 7. She competed in North American Dog Agility Council (NADAC) Veteran's classes. This is a class for dogs 7 years and older. The dog is allowed to jump 4 inches lower and is given an additional 10 percent time allowance to complete the course. She was awarded with the Superior Novice Agility Certificate, Superior Novice Gambler Certificate and the Superior Novice Jumpers Certificate.Injury On Sept. 13, 2001, Kahlar came up lame after chasing a ball in the back- yard six days before NADAC Agility Championships for which she had qualified. She was diagnosed with a right craninal cruciate ligament injury and severe bilateral hip dysplasia. She had functioned at a high level with the dysplasia prior to the acute right pelvic limb lameness.
She was placed on Rimadyl® for two weeks. A tibial plateau leveling osteotomy (TPLO) was performed on Sept. 26. Physical therapy began two weeks later after suture removal.
Physical therapy assessment Kahlar had significant rear limb atrophy. Left proximal thigh circumference was 36 cm, right 29 cm. She was about 70 percent weight bearing. The goals of physical therapy were to improve weight bearing to normalize gait and decrease atrophy. The ultimate goal was returning this animal to agility competition. Kahlar attended therapy once a week for five weeks, and her owner followed through with home exercises consistently.
On Kahlar's second visit, sit-to-stand and weight bearing on rear limbs using a 55 cm therapy ball were added. Swim time was increased to 10 minutes. Sit- to-stand was added to the dog's home exercise program (HEP).
During the third session, the stretches were discontinued. Walking in circles, high-stepping over obstacles, and crawling was added to the rest of the previous exercises. Swimming increased to 15 minutes. Dancing was added to HEP.
Inclines were added in the fourth session and swimming was increased to 20 minutes.
In the fifth and final treatment, swimming was increased to 25 minutes.
At discharge, after five visits, weight bearing on the right was 80 percent of the left and thigh atrophy had decreased to only a 2.5 cm. difference in circumference.
Radiographs on Nov. 19 showed bony healing was progressing, Kahlar had minimal to no lameness. In January 2002, Kahlar was released to increase exercise.
Four months after surgery Kahlar returned to agility training. By late March 2002, she was competing. Since surgery, Kahlar has been awarded Outstanding Open Agility Certificate, Outstanding Open Gamblers Certificate, and Veteran's Open Jumpers. She also earned sufficient points to qualify for the 2002 NADAC Championships.
Kahlar's owners report that since physical therapy, Kahlar's unique rear movement, affectionately referred to as her "funky back end," has been significantly reduced. Her jumping and running ability is improved from the strength she has gained.
