This is a surgery that’s weighted down in acronyms, so let’s first clear the air by defining some of those acronyms that may cause confusion. CBLO stands for CORA Based Leveling Osteotomy. CORA stands for Center Of Rotation of Angulation. This just refers to the intersection between the axis of two bones, basically how they rotate in relation to each other. This is a surgery that was created to fix injured CCL’s (there’s another one!). CCL stands for cranial cruciate ligament.
Now that we’re hopefully on the same page, the CBLO method for CCL repair is similar to a TPLO and a TTA in that it involves cutting bone in order to decrease the angle of, and sort of flatten, the knee joint in dogs with a torn CCL.
The idea with any of the above three surgeries is to change the basic shape of the knee joint so that the CCL isn’t needed anymore to prevent abnormal movement in the joint.
