Treating Knee Injury and Disease
Knee injury and disease is a common orthopedic condition for pets, and veterinary surgeons have been developing and refining surgical treatment options for decades.

Cranial cruciate ligament rupture is considered the most common cause of hind limb lameness in dogs.
The cranial cruciate ligament (CrCL) is like the anterior cruciate ligament, or ACL, in people. For humans, a traumatic injury is the typical cause of this ligament tear. For dogs, weakening of the ligament over time is another common reason, with genetics, breed predisposition, obesity, or other factors causing the ligament to degenerate.
TPLO, or Tibial Plateau Leveling Osteotomy, is a surgery performed on dogs to stabilize the stifle (knee) joint after a rupture to the Cranial Cruciate Ligament.
TPLO surgery adjusts the biomechanics of the dog’s knee joint to stabilize it and eliminate pain. The procedure changes the way a dog’s knee works.
The goal is to modify the geometry of the surfaces of the knee, neutralizing the forces that caused the torn ligament and instability of the knee joint.
CBLO, or CORA-Based Leveling Osteotomy, is a surgery performed on dogs to stabilize the stifle (knee) joint after a rupture to the Cranial Cruciate Ligament.
CBLO surgery is a variation of TPLO that also adjusts the biomechanics of the dog’s knee joint to stabilize it and eliminate pain. The procedure changes the way a dog’s knee works and is suitable for younger patients than conventional TPLO because it does not affect the growth plate of the bone.
The goal is to modify the geometry of the surfaces of the knee, neutralizing the forces that caused the torn ligament and instability of the knee joint.
Extracapsular lateral suture stabilization (ELSS) is a long-established surgical technique for addressing canine knee instability.
By placing a supportive suture of monofilament or woven tape outside the knee joint capsule, the procedure restores the mechanical support lost when a ligament tears. This surgical implant helps patients regain some or all of their mobility.
This support and stabilization can provide, particularly for smaller patients, restored normal or near-normal joint function.

Dr. Kim Tong, a board-certified veterinary surgeon based in the San Francisco Bay Area, frequently advises pet parents on what to expect when their dog (or cat) has hind-leg lameness and the cause is a torn or diseased knee ligament. Here are the top questions he hears, along with the key points he discusses with pet parents and vets when considering surgery.

Did you know pets have knee replacement options? Total Knee Replacement with the BioMedtrix Total Knee System can restore pain-free function!
Osteoarthritis of the knee is a degenerative joint disease that occurs when the protective cartilage within the knee breaks down due to inflammation. Its most common root cause is a primary injury or disease, such as cranial cruciate ligament rupture, osteochondrosis, or trauma.
Damaged joint surfaces will be replaced with a prosthetic joint designed to restore pain-free knee function.
The replacement knee consists of a metal component attached to the end of the femur (thigh bone) and a polyethylene component attached to the tibia (shin bone). Together, the components move like a normal, healthy knee joint.
