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).
