In the April 11, 2006 Wall Street Journal, there was a fascinating article on knee problems in dogs also known as a ruptured cruciate ligament. ("This Joint Problem Makes Dogs, Owners, Weak In the Knees: A Human Jock's Ailment Also Plagues Pooches; An $80 Pet's $6,000 Bill" By Kevin Helliker - subscription required)
I keep coming across this issue a lot in my investigation of pet insurance but I have to admit, I didn't know much about it until I read this article.
Being an athlete is a well-known risk factor for cruciate-ligament injury. A larger -- but lesser-known -- risk factor is being a dog. The number of dog knees undergoing cruciate-ligament repair each year in America is estimated to now exceed 1.2 million. That's about five times the number of human procedures -- even though humans outnumber dogs in the U.S. by nearly five to one. And it's not as though dogs have more knees: The joint on their front legs are elbows that aren't vulnerable to the problem.
Even more interesting is that the treatment is quite controversial...
Today, cruciate-ligament repairs are the most common surgical procedures for injured or diseased dogs. And inside veterinary medicine, controversy is raging over the best treatments.
A relatively new technique, called tibial plateau leveling osteotomy, or TPLO, involves breaking and resetting the tibia, the long bone below the knee, in such a way as to obviate the need for a cruciate ligament. The surgery costs from about $2,500 to $5,000 per knee. That's about twice the cost of the conventional procedure, which like the human equivalent involves constructing a replacement ligament.
Many respected academic veterinary experts believe that TPLO offers a faster and fuller return of function. But published proof of that theory is lacking, prompting some to avoid the procedure. For instance, surgeons don't perform it at the University of Pennsylvania School of Veterinary Medicine, says Gail Smith, chairman of the department of clinical research. He calls TPLO "a fashionable procedure."
Still, TPLO now is used for an estimated 50% of cruciate-ligament procedures in the U.S., and by all accounts that percentage is growing.
That's a lot of surgeries and a lot of what people would wish they had pet insurance for.
