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:
Advantages of TPLO
- Superior outcomes that are related to limb function and athletic mobility compared to older techniques like an extracapsular technique.
- Decreased progression of arthritis
Disadvantages of TPLO
- Need to perform osteotomy which requires healing of the bone
- If bone healing is thwarted for any reason, additional surgeries may be required
