"Stem cell therapy involves taking a pet's own adipose tissue from a ligament above the rib cage and rebuilding the joint, and so far, it's very promising," Becker said.
Lascelles added that it's also possible to perform total joint replacements, mostly of the hip, knee and elbow, in larger animals. In cats and small dogs, only the hip can be replaced.
"We can also create custom-built new joints for almost any size animal," he said.
There are also certain comfort measures people can take at home to ease their pet's pain.
"Heated orthopedic beds, stair or bed ramps and carpet runners can help alleviate the stress on the joints," Becker said.
And since one of the biggest problems contributing to arthritis pain is obesity, he added that people should make sure their pets maintain a healthy weight and stay active.
"Keeping a pet near its ideal body weight is the most important thing you can do to improve quality of life overall," Becker said.
