Experts in minimally invasive surgery

In addition, our surgeons are experts in minimally invasive techniques, the approach we take whenever possible. As a result, your pet experiences less pain, shorter hospitalization and a faster recovery.

Stem cell therapy involves three key steps:

The veterinary surgeon collects a small fat sample from your pet during a short procedure and the sample is shipped overnight to the stem cell laboratory

The stem cell laboratory processes the fat sample to concentrate the stem cells, and the stem cells are shipped overnight back to LIVS

The veterinary surgeon injects the stem cells into your pet at the site of injury or degeneration

Stem cell therapy for arthritis

LIVS surgeons also are on the leading edge in their use of stem cell therapy for treating chronic arthritis in pets. Stem cell therapy uses an animal’s own stem cells, which are capable of dividing and differentiating into a variety of cell types (such as cartilage, bone, or muscle). When injected into injured or degenerated joints, the stem cells allow healing and promote regeneration of injured tissues.
