Tibial Plateau Leveling Osteotomy, or TPLO

Tibial Plateau Leveling Osteotomy, or TPLO, is one of the most common repair options for canine cranial cruciate ligament, or ACL, ruptures. This procedure is often preferred for larger or more active dogs because it produces consistent outcomes. It can also be used on small pets as well. This surgery has a high success rate in dogs.

TPLO is performed by:

1. A circular cut (osteotomy) is made into the tibia. The contact surface, the tibial plateau, is rotated until it attains near level orientation, or is positioned approximately 90 degrees relative to the attachment of the quadriceps muscles.

2. A specially made bone plate and screws are then used to secure the osteotomy until it is healed. After the bone is healed, the plate and screws become unnecessary, but they are seldom removed (unless infection and/or irritation occurs).

Advantages and Disadvantages to the TPLO Technique

There are both advantages and disadvantages to choosing the TPLO technique to repair a ruptured cranial cruciate ligament. Here are some of the common advantages and disadvantages:
